The rise of quantum computing and its implications for current encryption standards are well known. But why exactly should quantum computers be especially adept at breaking encryption? The answer is a nifty bit of mathematical juggling called Shor’s algorithm. The question that still leaves is: What is it that this algorithm does that causes quantum computers to be so much better at cracking encryption? In this video, YouTuber minutephysics explains it in his traditional whiteboard cartoon style.

“Quantum computation has the potential to make it super, super easy to access encrypted data — like having a lightsaber you can use to cut through any lock or barrier, no matter how strong,” minutephysics says. “Shor’s algorithm is that lightsaber.”

Three scientists who laid the groundwork for the understanding of the odd “entangling” behavior of quantum particles have received the 2022 Nobel Prize in Physics.

French physicist Alain Aspect, Austria’s Anton Zeilinger and American John Clauser were honored for their experiments exploring the nature of entangled quantum particles.

A NASA X-ray spacecraft delivers new dimensions to the first images from the Webb telescope.

Images touch people in a way that words cannot. The unprecedented clarity of the Webb telescope’s first scientific images dazzled people across the world when they became public on July 12, 2022. Three months later, the team working on NASA’s Chandra X-Ray Observatory released new images of the same target objects: Stephan’s Quintet, galaxy cluster SMACS 0723.3–7327, and the “Cosmic Cliffs” of the Carina Nebula. An image that Webb later took of the Cartwheel Galaxy also got an update. All these visuals add more “turbulent” information about these structures and give the originals a whole new dimension.

Electronic computing and communications have advanced significantly since the days of radio telegraphy and vacuum tubes. In fact, consumer devices now contain levels of processing power and memory that would be unimaginable just a few decades ago.

But as computing and information processing microdevices get ever smaller and more powerful, they are running into some fundamental limits imposed by the laws of quantum physics. Because of this, the future of the field may lie in photonics—the light-based parallel to electronics. Photonics is theoretically similar to electronics but substitutes photons for electrons. They have a huge potential advantage in that photonic devices may be capable of processing data much faster than their electronic counterparts, including for quantum computers.

STOCKHOLM — Three scientists jointly won this year’s Nobel Prize in physics Tuesday for proving that tiny particles could retain a connection with each other even when separated, a phenomenon once doubted but now being explored for potential real-world applications such as encrypting information.

Frenchman Alain Aspect, American John F. Clauser and Austrian Anton Zeilinger were cited by the Royal Swedish Academy of Sciences for experiments proving the “totally crazy” field of quantum entanglements to be all too real. They demonstrated that unseen particles, such as photons, can be linked, or “entangled,” with each other even when they are separated by large distances.

It all goes back to a feature of the universe that even baffled Albert Einstein and connects matter and light in a tangled, chaotic way.

Our universe is a ridiculous place. It’s where all the silliest things we’re aware of happen. And chief among the silliness is the wacky idea of…

This is pioneering work for quantum teleportation as well making entanglement the main way for quantum teleportation communications in the future.

Award goes to three experimental physicists whose pioneering research has laid the groundwork for quantum information science.

Aspect, Clauser, and Zeilinger won the prize for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science.

The Nobel Prize in Physics has recently been announced.

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2022 to Alain Aspect, John Clauser, and Anton Zeilinger for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science.

They say that nobody understands quantum mechanics. But thanks to these three pioneers in quantum entanglement, perhaps we do.
