Nobel Prize 2022 winners in Physics go to a trio for solving quantum science mysteries

France-born Alain Aspect, American John Clauser and Austrian scientist Anton Zeilinger were on Tuesday awarded the Nobel Prize in Physics "for experiments with entangled photons, establishing the violation of John Stewart Bell inequalities and pioneering quantum information science".

They each conducted groundbreaking experiments using entangled quantum states, where two particles behave like a single unit even when they are separated.

Their results have cleared the way for new technology based upon quantum information.

"The ineffable effects of quantum mechanics are starting to find applications. There is now a large field of research that includes quantum computers, quantum networks, and secure quantum encrypted communication," the Royal Swedish Academy of Sciences said in a statement.

One key factor in this development is how quantum mechanics allows two or more particles to exist in what is called an entangled state.

What happens to one of the particles in an entangled pair determines what happens to the other particle, even if they are far apart.

For a long time, the question was whether the correlation was because the particles in an entangled pair contained hidden variables, instructions that tell them which result they should give in an experiment.

In the 1960s, John Stewart Bell developed the mathematical inequality that is named after him.

This states that if there are hidden variables, the correlation between the results of a large number of measurements will never exceed a certain value.

However, quantum mechanics predicts that a certain type of experiment will violate Bell's inequality, thus resulting in a stronger correlation than would otherwise be possible.

"Clauser developed John Bell's ideas, leading to a practical experiment. When he took the measurements, they supported quantum mechanics by clearly violating a Bell inequality. This means that quantum mechanics cannot be replaced by a theory that uses hidden variables," said the Academy.

Some loopholes, however, remained after Clauser's experiment.

Aspect developed the setup, using it in a way that closed an important loophole. He was able to switch the measurement settings after an entangled pair had left its source, so the setting that existed when they were emitted could not affect the result.

Using refined tools and a long series of experiments, Zeilinger then started to use entangled quantum states. Among other things, his research group has demonstrated a phenomenon called quantum teleportation, which makes it possible to move a quantum state from one particle to one at a distance.

"It has become increasingly clear that a new kind of quantum technology is emerging. We can see that the laureates' work with entangled states is of great importance, even beyond the fundamental questions about the interpretation of quantum mechanics," says Anders Irback, Chair of the Nobel Committee for Physics.

The prize amount of 10 million Swedish kronor will be shared equally between the winners.

Samsung Galaxy S23 case leak reveals camera similarity with Samsung Galaxy Z Fold 4 5G

After the S22 series, Samsung is all set to bring on the new Samsung Galaxy S23 series. The S23 series will include three phones - Galaxy S23, S23 Plus, and S23 Ultra. But, prior to the announcement, tipster Ice Universe, a well-known source for updates relating to Samsung, uploaded images of 2 protective case designs in lavender and bright green.

The leak confirmed a new camera design with triple cutouts, the LED flash placement next to the camera sensors and the power and volume buttons aligned on the right side of the Galaxy S23. The camera arrangement holds similarities with the Samsung Galaxy Z Fold 4 5G, launched early this year.

The S23 Ultra is in line with the S22 Ultra

The design of the S23 series is more or less intact with the S22 series, but the specifications are expected to vary. The Android phone will have a  6.1-inch AMOLED display with a Full HD+ resolution and will run on a Snapdragon 8 Gen 2 SoC or an Exynos 2300 chipset, which currently is an apple of accord because the launch location is still unknown. The series is rumoured to support a 25W fast charging.

While the internet gushed with suggestions and assumptions about the details of the new Samsung Galaxy S23 series, it is yet to be known how Samsung will amaze its users with the recent launch.

Google Messages is rolling out reactions for SMS compatible with Apple iMessage

Google Message is getting the ability to react to SMS texts. While SMS is one of the oldest ways of sending text messages, some users prefer texting with their near and dear ones over SMS. For them and others who occasionally open text messages, they will be able to send an emoji reaction via SMS, which was only possible with RCS.

Some Google Messages users are able to react to SMS with an emoji 

Although the feature is not available to all the users yet, a recent 9to5Google report says that a few Google Message users are "able to react to SMS texts." The way it works is that Google Messages users have to press and hold a text message until they see seven emoji reaction options at the top. Then, they can click on the desired emoji reaction. Now, the reaction shows in two different ways to the recipient. 

If the recipient uses the Google Messages app, the emoji reaction appears at the bottom right corner of the message bubble. However, when the recipient is not using Google Message (or using an iOS device), the emoji reaction appears with a short message, highlighting what it has been sent as a reaction to in quotes. In a nutshell, the feature adds liveliness to the old way of texting others and bridges the gap between Google Messages and Apple's iMessage. 

This feature bridges the gap between Google Messages and Apple’s iMessage

For those who are catching up, the Google Messages app has supported Rich Communication Services, abbreviated as RCS, since 2020. It is a new messaging protocol that lets users share high-quality files, such as videos and photos, over boring text messages supported by SMS. However, Apple sticks to iMessage, a platform that works seamlessly between iOS devices but converts messages from Android phones to SMS and MMS. Google calls these, 'out-of-date technologies from the 90s and 00s' and has been after Apple to adopt RCS for quite some time.

However, Apple is not in the mood to pave the way for RCS. When asked about any plans to add RCS to iMessage at the Code Conference 2022, Apple CEO Tim Cook stated, "I don't hear our users asking that we put a lot of energy on that at this point." Though Apple is not making any efforts to improve cross-platform messaging, the Google Message update will surely enhance users' experience.

WhatsApp screenshot blocking feature appears in the latest beta app for Android: See how it works

WhatsApp is finally getting a feature that should have been a part of it long before. Well, we are discussing the WhatsApp screenshot blocking feature which is currently being tested on the beta versions of the app. More precisely, WaBetaInfo tells us that the WhatsApp beta for Android 2.22.22.3 prevents the recipients of ‘view once’ messages from being screenshotted. He has shared some images of this thing in action. Let’s have a look.

WhatsApp screenshot blocking: How it works

WhatsApp screenshot blocking

According to WaBetaInfo, once this feature is active when you try to take a screenshot of a view-once image or screen recording of a view-once video, all you get is a black screen. WhatsApp will show you a toast message that “can’t take a screenshot due to security policy”.

Apparently, this won’t work even if you use third-party extensions to grab the screenshot. 

Here are some other things you need to know about the WhatsApp screenshot blocking feature:

The other person won’t be notified that somebody is trying to take a screenshot or screen recording. Rather the person attempting the act will get the aforementioned toast message and black screen. At the moment, this blocking restriction is applicable on images and videos only. That means you can still take screenshots of chats and messages even if some of them are of a ‘view-once’ nature. Other limitations include the clamp on forwarding, exporting, or saving disappearing images and videos. All that said, nothing is stopping a person from taking a photo or video of the view once content using another phone or camera. 

The screenshot blocking feature is spotted as part of the WhatsApp beta for Android 2.22.22.3 which is available through the Google Play Beta Program. However, since this is still in beta, you could expect some changes or improvements to its implementation.

iPhone 14s Crash Detection feature fails the collision test: Heres Apples justification

The Crash Detection feature, which is present in iPhone 14 models and an Apple Watch, has undergone a new test that reveals when it correctly fires and when it does not.

In a video from the Wall Street Journal, a demolition derby driver repeatedly rammed two distinct cars. He had a Google Pixel in the vehicle, which can also detect crashes, and an Apple Watch Ultra with an iPhone 14 model, reports AppleInsider.

Next, an iPhone 14 and Google Pixel were also placed side-by-side in each vehicle.

Testing showed that the Apple Watch worn by the driver was successful at detecting crashes. However, the iPhone didn't detect any of the impacts inside the first car, the report said.

The Google Pixel did detect one crash inside the driver's vehicle, but neither phone went off inside the car that got crashed into.

With car number two, the testers drove it around before crashing to make the smartphones think it was legitimate. But again, the crash did not trigger the smartphones.

When WSJ contacted Apple and Google with the results, Apple said a lack of data could be why the iPhone 14 didn't detect the crashes. Perhaps it was because it wasn't connected to CarPlay, or the tester didn't drive around the vehicle long enough.
