Modern Jedi Physicists Freeze Light In Mid-Air: Bringing Quantum Computers Closer To Reality

Posted by in categories: computing, particle physics, quantum physics

“It’s clear that the light is trapped — there are photons circulating around the atoms,” Everett says. “The atoms absorbed some of the trapped light, but a substantial proportion of the photons were frozen inside the atomic cloud.”

Co-researcher Geoff Campbell from ANU explained that while photons commonly pass by each other at the speed of light without any interactions, atoms interact with each other more freely.

“Corralling a crowd of photons in a cloud of ultra-cold atoms creates more opportunities for them to interact,” Campbell says.

Quantum research race lights up the world

Posted by in categories: computing, quantum physics

The race towards quantum computing is heating up. Faster, brighter, more exacting – these are all terms that could be applied as much to the actual science as to the research effort going on in labs around the globe.

Quantum technologies are poised to provide exponentially stronger computational power and secured communications. But the bar is high – advances are hard won and competition is intense.

At the forefront of the candidates to implement such technologies is the field of quantum photonics, particularly light sources that emit photons one at a time to be used as carriers of information.

Jedi scientists freeze light in midair to bring quantum computers a step closer to reality

Posted by in categories: computing, particle physics, quantum physics

Remember that scene in “The Force Awakens” where the dark side warrior Kylo Ren stops a laser blast in mid-air? In a Canberra laboratory, physicists have managed a feat almost as magical: they froze the movement of light in a cloud of ultracold atoms. This discovery could help bring optical quantum computers from the realms of sci-fi to reality.

The experiment, published in a paper this week, was inspired by a computer stimulation run by lead researcher Jesse Everett from the Australian National University. The researchers used a vaporized cloud of ultracold rubidium atoms to create a light trap, into which they shone infrared lasers. The light trap constantly emitted and re-captured the light.

IBM Just Made Artificial Neurons to Help Computers Mimic Our Brains

Posted by in categories: computing, neuroscience

In Brief.

Scientists at IBM achieve another breakthrough by recreation of artificial neurons that successfully respond to phase changes due to electric signals while using very little power, much like the human brain.

Even after all the developments in computers, the human brain remains by far, the most complex, sophisticated, and powerful computer in existence. And for decades, scientists have been looking for ways to translate its processing mechanisms into a system that machines can replicate.

Nanosensors help understand how tumors will respond to therapies

Posted by in categories: biotech/medical, computing, engineering, health

MIT researchers have designed nanosensors that can profile tumors and may yield insight into how they will respond to certain therapies. The system is based on levels of enzymes called proteases, which cancer cells use to remodel their surroundings.

Once adapted for humans, this type of sensor could be used to determine how aggressive a tumor is and help doctors choose the best treatment, says Sangeeta Bhatia, the John and Dorothy Wilson Professor of Health Sciences and Technology and Electrical Engineering and Computer Science and a member of MIT’s Koch Institute for Integrative Cancer Research.

“This approach is exciting because people are developing therapies that are protease-activated,” Bhatia says. “Ideally you’d like to be able to stratify patients based on their protease activity and identify which ones would be good candidates for these therapies.”

Will quantum teleportation defeat quantum decryption?

Posted by in categories: computing, encryption, finance, quantum physics, security

Nice article; however, not sure if the author is aware Los Alamos already has a quantum net as well as some Europe banks have the capabilities and 4 months ago it was announced that a joint effort by various countries from Europe, Asia, etc. have come together to re-engineer the Net infrastructure with QC technology…


Maybe the quantum will giveth what the quantum taketh away… at least when it comes to secure transmissions.

There’s been much speculation that emerging quantum computers will become capable of breaking advanced public key cryptography systems, such as 2048-bit RSA. This might leave encrypted data transmissions exposed to anyone who happens to own such a quantum computer.
