Jedi scientists freeze light in midair to bring quantum computers a step closer to reality
Posted by Shane Hinshaw 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.

Robotic surgery tech provides users with a sense of touch
Posted by Shane Hinshaw in categories: biotech/medical, robotics/AI
A new system called HeroSurg, developed by researchers at Deakin and Harvard Universities, is set to increase what surgeons can achieve via robotic surgery, using a haptic feedback system to provide a sense of touch. It also brings other improvements over existing tech, such as collision avoidance, to make robotic surgery safer and more accurate.
Robotic surgery, wherein human-controlled robots perform delicate surgical tasks, has been around for a while. One great example of the tech is the da Vinci robotic surgical system from Intuitive Surgical – a setup made up of numerous robotic arms, a console to operate the instruments, and an imaging system that shows the surgeon what’s happening in real time. In 2008, Professor Suren Krishnan, a member of the team behind HeroSurg, became the first surgeon to perform ear, throat and nose operations using the da Vinci robotic surgical system.
Since then, we’ve seen numerous breakthroughs, including improvements to the original da Vinci system, and other robots emerging capable of achieving impressive tasks, such as performing surgery on a beating heart, or successfully stitching soft tissue.

D-Wave Systems previews 2000-qubit quantum processor
Posted by Sean Brazell in categories: energy, information science, quantum physics
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.

Massive Earthquake Along the San Andreas Fault Is Disturbingly Imminent
Posted by Sean Brazell in category: futurism
Anyone who is, or will be, anywhere near these potentially severe earthquake damage zones, be safe!
A series of quakes under the Salton Sea may be a signal that the San Andreas Fault is on the verge of buckling. For the next few days, the risk of a major earthquake along the fault is as high as 1 in 100. Which, holy crap.
