Quantum cryptography; an untangled guide to the future of cybersecurity

As our lives become increasingly more digital, new opportunities for hacking, impersonating, and thefts arise. Current encryption techniques are far from perfect and might soon prove obsolete at the hands of phenomena we do not fully understand.

Step into the unknown

From wristwatches to the supercomputers that run the Large Hadron Collider, all modern electronic devices use binary code, a two-symbol system consisting of 0s and 1s. The vision for new technology, however, is founded on quantum bits, widely known as qubits. Typically taking the form of photons and electrons, qubits are units of encoded quantum information. When harnessed, these subatomic particles will offer the raw processing power and security, the likes of which we’ve never experienced. But how? In order to dive deeper into the abstract, we must first take a look at the history of quantum physics.

A short history lesson on Quantum cryptography

Quantum cryptography; an untangled guide to the future of cybersecurity
Today’s available encryption techniques are still in working mode but might soon prove to be obsolete. Quantum cryptography offers an untangled guide to the future of cybersecurity and we might be living in heaven already with it!

The year was 1900, and physicist Max Planck had just presented his quantum theory to the German Physical Society. Planck proposed that energy, just like matter, was made up of individual units. 5 years later, Albert Einstein theorized that radiation could also be observed in a similar manner. This eventually led to the proposition in 1924 that particles can behave like waves and vice versa – known as Louis de Broglie’s principle of wave-particle duality.

No more than 3 years later, Werner Heisenberg came up with what became known as the uncertainty principle, where he proposed that a precise measurement of two complementary values was impossible, e.g. the position and momentum of a subatomic particle. Its notion defied the mathematical laws of nature, prompting one of Einstein’s most famous quotes,

God does not play dice with the universe”.

What do a cat and a physicist have in common?

Over the years, the most powerful theoretical minds have contributed to our understanding of quantum theory – a process that is still ongoing. To this day, however, one of the most commonly taught interpretations of quantum mechanics is that of Niels Bohr and Werner Heisenberg, devised from 1925 to 1927. Known as the Copenhagen interpretation, their work claimed that no object in the universe can be assumed to have specific properties until it is measured. This concept became known as superposition.

Superposition is best explained through the paradox of Schrodinger’s Cat, named after physicist Erwin Schrodinger. To visualize the concept, imagine a cat in a sealed box with a vial of poison inside. We cannot know whether the animal is dead or alive until we open the box, so during this period of uncertainty, it is both dead and alive. By the same token, a qubit can exist in all possible states until it is measured.

Brothers in arms

Described by Einstein as “spooky action at a distance’, entanglement is a key phenomenon in quantum physics that signifies a shared, quantum state between a pair or group of qubits that makes each member of the pair or group inherently dependent on the others. In entanglement, a change in the state of one qubit immediately affects the others in a predictable way, for instance, in a pair of qubits with a measured total spin of zero, when one is known to have a clockwise spin, the other qubit must then have a relative counter-clockwise spin. What is interesting about entanglement is that so far no one has been able to explain exactly how or why it occurs. Spooky.

Absolute power

The practical application of quantum theory is a tantalizing prospect for technological breakthroughs, particularly in computing. Thanks to superposition, quantum computers can perform calculations for multiple possibilities simultaneously, as opposed to the one-at-a-time nature of digital machines. Furthermore, while conventional computers require additional bits to increase their processing capabilities, quantum computers use entangled qubits to provide unparalleled efficiency and raw power. The implications are colossal, spanning across fields and industries. From molecular modeling to forecasting in weather and finance, from machine learning in the automotive and medicine to particle physics, the future does look bright.

What’s the catch?

China is one of the main players in quantum research, having recently used its Micius satellite to successfully beam entangled pairs of photons to three optical telescopes over a record 1,203 kilometers, besting the previous record by almost 1,100 kilometers. Unfortunately, only one pair of photons out of the 6 million beamed each second survived the journey through our atmosphere. This is because even the smallest change in the environment, like a loud noise, can destroy quantum properties and result in computational errors – an occurrence known as decoherence.

To maintain their unique properties, qubits should be kept inside vacuum chambers at all times, having limited to no interaction with outside stimuli, which isn’t always possible. Decoherence is one of the biggest challenges to unlocking the full potential of quantum mechanics, but the prize for overcoming it is everything. The global leader in quantum computing is going to have an unthinkable advantage over the rest of the world. It’s a sprint, not a marathon.

What if I told you…

The world’s most popular encryption technique has many flaws that make it prone to interception and decryption. The effectiveness of RSA encryption relies on the difficulty of solving multi-factor problems involving large prime numbers. RSA keys, needed to access the encrypted message, are constantly at risk of factoring attacks, making them an easy target for quantum computers thanks to their multi-problem solving properties. The solution? Quantum networks. When operational, these will most likely be a specialized branch of the world wide web, offering secure data transfer, and more, to future you.

The knight in shining armour

But we do not have to wait 10 years for our data to be secure. Quantum cryptography is already here in the form of Quantum Key Distribution or QKD for short. QKD uses the principles of superposition to create an encryption system based on physics rather than, traditionally, mathematics. In order to relay information securely, the sender creates an encryption key using qubits, which are sent to the recipient. The sender and recipient then use key sifting to determine whether the operation was successful. Had the encoded qubit been measured by a third-party, the sender and recipient of the data would both be alerted by the collapse of the entire operation due to decoherence. The security of this encryption technology combined with the ability to sound an alarm when jeopardized is revolutionary for cybersecurity.


In a perfect world, the new ceiling in cybersecurity would make our planet an objectively better place. Quantum communication would provide freedom and security for those under suppressive governments. The safety of financial transactions would be at an all-time high thanks to quantum cryptography. We would be able to get in touch with our friends and family in total privacy via quantum networks. The subsequent developments in artificial intelligence would bring us closer to technological singularity, where miraculous advances would happen on an almost daily basis. Our grandchildren might even call it the “quantum age”. Sounds great, doesn’t it?

How to Delete Duplicate Contacts in Lotus Notes?

Today, we are going to run another How to guide as we normally do on TechAtLast. The focus is on how to remove or delete duplicate contacts in Lotus Notes.

IBM Lotus Notes is an email client that uses the NSF file format as its storage pool where all the information associated with a Notes account gets stored. NSF is an acronym for Notes Storage Facility and it stores its data in a unit refers to as notes. The file names.nsf consists of personal address book information of each account like phone contacts, locations, email addresses, connections, etc.

Many times, duplicate contacts are generated in NSF files of multiple Notes accounts of the employees working in the same organization consuming the unnecessary space of Lotus notes Storage. It is a daunting task to remove duplicate contacts in lotus notes, especially when you are dealing with bulk contacts.

In this tutorial, we are going to discuss different methods and techniques on how to remove duplicate contacts in Lotus Notes. But before moving towards that, let’s understand how duplicate contacts are generated.

How to Delete Duplicate Contacts in Lotus Notes (How to remove duplicate contacts in Lotus notes)
Lotus Notes is an email client designed by IBM for organizations that helps facilitates communication and storage of important data. If you want to remove duplicate contacts in Lotus notes, worry not. In in this guide, you are going to learn how to delete duplicate contacts in Lotus Notes for free and with ease.

How duplicate contacts are generated?

Most of the Lotus Notes user faces problems when their duplicate contacts are generated in the address book. Some causes that lead to the generation of duplicate contacts are listed below:

  • When two or more (names.nsf) files of a single account of Lotus Notes are merged to create a single file, then it may generate duplicate contacts.
  • When the address book of ex-employee is imported to another employee’s address book working in the same organization, duplicate contacts may be created.
  • When the names.nsf file, which is downloaded as an attachment in the Lotus Notes account is synchronized with the contacts already present in the address book, duplicity is likely to occur.

Why Remove Duplicate Contacts in Lotus Notes?

There are many reasons to delete duplicate and identicall contacts that are auto-generated inside IBM Lotus Notes. Some of them are:

  • When the contact file size is larger what could be managed. For example, a 20,000 contact list is a headache for the owner.
  • Reduction in the speed of the system due to overused storage space.
  • Just like the PST file, or Microsoft Outlook data file, the NSF database has a storage limit of 64GB and once this allocation gets filled up, the system begins to malfunction. You can experience data loss as a result of too many files struggling for a limited space.

How to Delete Duplicate Contacts in Lotus Notes

Managing the address book of a Lotus Notes account is a tedious task if the contacts file is large. In addition, duplicate contacts that are generated unintentionally use lots of space that may cause the performance rate of Lotus Notes to slow. Some of the workarounds to remove duplicate contacts in Lotus Notes account are:

Workaround to Remove Duplicate Contacts in Lotus Notes

Step 1. One of the workarounds is to select the duplicate contact individually and delete them to save space. This option is not feasible when there is a large number of contacts present in a single account as it may consume a lot of time.

Step 2. Another method to find the duplicate contacts and delete them is by running Lotus scripts in the Domino agent written by Purna. However, these manual methods do not give satisfactory results and it is very difficult for non-technical people to use the scripts.

Professional Tool for Removing Duplicate Contacts From Lotus Notes

The most effective way to remove the redundant contacts easily from the NSF files is by using a third-party software tool like NSF duplicate remover. The software combine duplicate names.NSF files and generates a single NSF file after comparing the duplicate contact within the files and removing the same contacts. In case of emails also, the tool removes the duplicate emails from Lotus Notes NSF Files.

The software can merge several NSF files of many Lotus Notes accounts at a time, search for duplicate contacts among them, and generate a new NSF file removing the duplicate contacts. The software will first give priority to add the NSF file either by file or folder. The user needs to check the box for Remove duplicate if he/she wants the duplicate contacts to be removed among the multiple NSF files. The saving location where the result will be stored is specified by the user. The tool will provide the new Lotus Notes file where all the contacts from different names.nsf files will be stored without any duplicate contacts. And an additional benefit is you can remove duplicate email in Lotus Notes.

Final Verdict!!

This technical guide focused on How to Delete Duplicate Contacts in Lotus Notes. Both manual methods and professional tools are prescribed. Now it up to to you to choose any of them. Thanks for Reading.

Recycle VHS Tapes: How to Recycle Old VHS Tapes [3 Practical Steps To Follow]

In their heyday, VHS tapes were the most popular way to record videos and watch movies, but in just a couple of decades, the technology that once seemed so advanced has become obsolete and unpopular.

However, even though VHS cassettes can’t compete with the digital video technology available today, the fact remains that there are still millions upon millions of tapes in people’s closets, attics, or storage units, never to be used again.

And that raises the question – is there any way to recycle these tapes and ensure that they don’t end up polluting the earth for hundreds or even thousands of years?

Well, to answer that question, let’s look at some of the possible ways how you could recycle your old VHS tapes, as well as how to save their contents.

Here are the steps on how to recycle old VHS tapes;

OLD VHS TAPES RECYCLING - This Is How to Recycle VHS Tapes
In their heyday, VHS tapes were the most popular way to keep memories, here are possible ways to recycle VHS tapes, and save their contents. To do that, we have outlined below step by step guidelines for recycling old VHS tapes.

1. Put Them Up for Sale

When you find an old box of VHS tapes in your garage or storage unit, they may not look like much.

Covered in dust and worn down, these tapes may not seem valuable, so most people just assume that no one would be interested in buying them and end up keeping them where they are or throwing them away.

However, in some instances, you may be surprised to find that some items in your collection have aged quite well and may actually be worth a significant amount of money.

Some collectible and rare old VHS tapes can be worth thousands of dollars – for instance, if you have an original tape of the 1978 movie Halloween, you could sell it for as much as around $13,000!

Obviously, these types of situations aren’t common, but you may find that you accidentally held on to an item that now has immense collectible value, so it’s always a good idea to check before throwing them out or giving them away.

Even if you only get a few bucks for the tapes it’s still better than nothing and that way you’d at least be ensuring that the tapes remain used and valued.

While tapes haven’t yet become widely accepted as a vintage format, there are collectors all over the world who value old VHS tapes and are willing to pay a premium for the right ones, so you should make sure to take advantage of this opportunity if your collection has valuable and rare items.

2. Send the Old VHS Tapes to a Specialized Recycling Company

Now, if you go through your VHS tape collection and don’t find anything of value, or if your collection mainly consists of home videos that are only valuable to you and your family, you will need to find other ways of recycling your collection besides selling it off.

Luckily, today there are plenty of recycling companies that accept old VHS tapes and know how to recycle them effectively so that they don’t end up in a landfill.

To get started, simply get on Google and type in “VHS tape recycling near me” and go through some of the main options, looking at the conditions that the company has, its policy, as well as the location so that you know that the option convenient for you.

Some companies will accept a certain amount of tapes for free, while others may charge a few for taking and processing them, but when you’re using a certified recycling company, you at least know that the tapes won’t become a burden for the environment.

What’s more, when using these types of services, you can sometimes even arrange for them to pick up the tapes from your home, saving you time and effort of having to drive the tapes to the recycling location yourself.

3. Repurpose Them

Sometimes, you may find that your collection of old tapes doesn’t have to go in the trash at all and that you may be able to repurpose your collection to serve you for many years to come.

Even if you don’t need the tapes for their contents, they are interesting and versatile objects that can be used in a variety of ways, depending on how much effort you are willing to put in and how creative you can be.

Today, many interior designers end up using vintage items to create exciting furniture or decorations, so you could use your tapes as a basis or a detail for anything from tables, shelves, clocks, or even wall decorations.

You can also repurpose the cassette tape into a storage box for smaller items such as jewelry or small accessories.

And if you’re feeling particularly creative, you can even use VHS tapes to create art, repurposing and remaking the tapes into something completely new and unique.

Point to Consider: Digitize Your Memories

When you’re trying to decide how to get rid of the old VHS tapes that are taking up space in your closet, you may be overlooking one of the most important considerations – how valuable is the content contained on the tapes, and can you allow yourself to get rid of them?

If the tapes contain old movies, they may not have too much sentimental value, as you can get the same movies in digital formats that provide much better quality.

However, if your tapes contain personal moments and home videos, they are irreplaceable, so while the format in which they are stored may be inconvenient and outdated.  This is why you must make an effort to preserve the captured memories residing in your old VHS tapes.

Luckily, that process doesn’t have to be complicated – there are many tape conversion service providers that have the experience and the equipment necessary to convert your tapes into a digital format.

What’s more, when you use a convert VHS to digital service, the quality of the tapes can be restored and sometimes even improved, which will allow you to enjoy seeing your memories in better quality that will not decay over time.

Instead of having to deal with VHS tapes that take up space and continually decay year after year, you can have all of your videos stored in a digital format and ensure that the memories will be preserved for future generations to enjoy.

How to Protect Your Privacy in Windows 10 – Follow These 5 Steps

If you are familiar with search engine service providers such as Google, DuckDuckGo, or Bing, you’ll agree with me that “how to protect your privacy“, or “how do I protect my privacy“, or “how to stay secured online” are top search phrases that comes higher amongst the list of things people search for on a daily basis.

Privacy is one of the most debatable topics nowadays. Everyone wish to have their privacy intact and for this, they are ready to spend any amount of money. However, spending the money on unnecessary instruments is not a full proof solution to keep your privacy protected. But if we remain a bit alert and follow some common tweaks then we can ourselves protect our privacy. Now when it comes to the Windows 10, Microsoft is criticized for some of its features that don’t seem to be in accordance with the privacy rules and policies that one needs to follow. But guys do believe that it’s not that much difficult to protect your privacy in Windows 10. In this article, we will discuss how following some simple tips will protect your privacy in Windows 10.

Expert’s Guide on How to Protect Your Privacy in Windows 10

How to Protect Your Privacy in Windows 10 PC
If protecting your privacy is all that matters to you right now, using Windows 10 won’t directly help except you follow these tips for staying safe.

Turn Off Location Access

This is one of the most basic features that we never turn off, and in turn, we let our current location known to others. This means if you have turned on your location service then Windows, services and other apps can use your location by sending location-specific offers or ads to you. If you are ordering some food from the nearby restaurant then turning on the location access is ok but turning on your location access all the time doesn’t make any sense. Therefore, we advise you to disable your location access by following the steps below:

      •    Click on Windows Start button and select Settings (gear icon) > Privacy > Location.Turn Off Location Access to protect your privacy
      •    Now click on Change button to toggle off location service for the device.
      •    That’s it now your location service is disabled

Moreover, you can also give your location access to some of the apps, instead of allowing it for every app.

Stop Notification to Show on Lock Screen:

It is a common practice followed by every user to lock his screen while moving away from it. But if you have let the notifications to pop up even on the lock screen then it’s a serious concern to your privacy. Therefore, it is highly recommended to turn off your notification while your computer is locked. To turn off notifications appearing on lock screen follow the below steps:

      •    Click on Windows Start button and select Settings (gear icon) > System > Notifications & actions.Stop Notification to Show on Lock Screen
      •    Now toggle off the option, Show notifications on the lock screen.
      •    This will stop all the notifications from appearing on the lock screen.

If you are more concerned about your privacy, then you can also disable other types of notifications as well.

Never Make your Account Information Public:

Keeping your account info private is another method to not only protect your id but also privacy in Windows 10. This is because if you allow apps to access your account information then they can view your name, picture, and other account details. But once denied none of the apps can view your account information keeping your privacy intact. To do so all you need is to follow the steps below:

      •    Click on Windows Start button and select Settings (gear icon) > Privacy > Account Info.Never Make your Account Information Public
      •    Now click on Change to turn off the account info access.
      •    Also, toggle off the option that allows an app to access your account info.

Manage your Privacy using Privacy Dashboard of Microsoft:

Microsoft Privacy Dashboard is a less known tool that helps you to manage your privacy. By logging into this dashboard, you can not only view but also delete the data at once, that is gathered by Microsoft. To get started all you need to do is to visit the following link and sign in with your Microsoft account. Once signed in you can view and delete all your browsing history collected while using Microsoft Edge and Cortana, clear your search history, clear all your location information, manage apps and services that access your data and much more. And still, if you have some other privacy questions and concerns then you can also contact Microsoft privacy team.

Turn Off Timeline to Protect Your Privacy:

While for many users Windows Timeline feature is one of the most loved features, on the other side it is a matter of concern for others. This smart feature helps you to resume your activities from where you have left not only on the current PC but also from all the PC where you have signed in. Now, in order to make that possible Windows do gather information about your activities from all the PC, you are signed in. So, if you too feel this as a privacy threat then you can easily turn this off. To do so, please follow the below steps:

      •    Click on Windows Start button and select Settings (gear icon) > Privacy > Activity history.Turn off timeline on Windows 10 if you want to be secured.
      •    Now uncheck the option, Store my activity history on this device.
      •    Also, uncheck the option, Send my activity history to Microsoft.

Now Windows 10 will not gather information about your activities.

So, readers, now you can yourself realize that protecting your privacy in Windows 10 is not an uphill task. You have to follow just the above-discussed tweaks and keep your privacy intact.
