New Quantum-Powered AI Exoskeleton Lets One Person Do the Work of Four

Posted by in categories: computing, cyborgs, quantum physics, robotics/AI, wearables

As the saying goes, “If you want something done right, you gotta do it yourself,” and it seems that you’ll soon be able to get a lot more done using artificially intelligent, high-tech exoskeleton Kindred. It’s the product of a startup created by quantum computing company D-Wave’s founder Geordie Rose, and according to the venture capital firm funding Kindred, the device “uses AI-driven robotics so that one human worker can do the work of four.”

Based on a patent application, the wearable system is envisioned as a 1.2-meter tall humanoid that may be covered with synthetic skin. It will include a head-mounted display and an exo-suit of sensors and actuators that carries out everyday tasks.

Essentially, it looks something like Spider-Man’s Doctor Octopus on the outside, but on the inside, Kindred utilizes quantum computation, a way of information processing and storage that is much faster and more powerful than that used by conventional computers. Data “learned” by the suit can be taught to other robots, allowing those robots to then perform the tasks autonomously.

First ever scalable quantum computer developed by scientists

Posted by in categories: business, quantum physics, supercomputing

Scientists all around the world are working towards making the quantum computing a reality for past few years as it will bring another revolution in the world of technology. Quantam computers are thousands of times faster and way smaller than the conventional computing devices as they use photons to do computing and are also compatible with fibre optics.

A team of researchers from the University of Innsbruck in Austria claims that they have invented world’s first scalable quantum computer. Although the device is still several years behind coming to reality but still scientists consider it as a giant leap towards bringing quantum computers into people’s hands.

From hypothetical models in last decade to practical models now is promising. Former Microsoft CEO Bill Gates believes that we will make quantum computers by next decade. This promising, complex technology may soon amplify the capabilities of today’s computers, which will greatly benefit science and business organizations by helping them work faster and more efficiently. Quantum computers are next step of computers and they can solve problems with ease which are nearly impossible for computers and supercomputers of current generation.

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.

D-Wave Systems previews 2000-qubit quantum processor

D-Wave 2000-qubit processor (credit: D-Wave Systems)

D-Wave Systems announced Tuesday (Sept. 28, 2016) a new 2000-qubit processor, doubling the number of qubits over the previous-generation D-Wave 2X system. The new system will enable larger problems to be solved and performance improvements of up to 1000 times.

D-Wave’s quantum system runs a quantum-annealing algorithm to find the lowest points in a virtual energy landscape representing a computational problem to be solved. The lowest points in the landscape correspond to optimal or near-optimal solutions to the problem. The increase in qubit count enables larger and more difficult problems to be solved, and the ability to tune the rate of annealing of individual qubits will enhance application performance.

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.
