Quantum Teleportation Goes the Distance

• October, 2012

Record-Breaking Distance of 143 Kilometers Through Free Space An international research team including several scientists from the University of Waterloo has achieved quantum teleportation over a record-breaking distance of 143 kilometres through free space. The experiment saw the successful teleportation of quantum information — in this case, the states of light particles, or photons — between the Canary Islands of La Palma and Tenerife. The breakthrough is a crucial step toward quantum communications via satellite. Unlike the teleportation of solid objects popularized in science fiction,

Making sense of a visible quantum object – Aaron O’Connell

• June, 2012

Physicists are used to the idea that subatomic particles behave according to the bizarre rules of quantum mechanics, completely different to human-scale objects. In a breakthrough experiment, Aaron O’Connell has blurred that distinction by creating an object that is visible to the unaided eye, but provably in two places at the same time. In this talk he suggests an intriguing way of thinking about the result.

Quantum Computer Built Inside a Diamond

• April, 2012

Diamonds are forever — or, at least, the effects of this diamond on quantum computing may be. A team that includes scientists from USC has built a quantum computer in a diamond, the first of its kind to include protection against “decoherence” — noise that prevents the computer from functioning properly. The demonstration shows the viability of solid-state quantum computers, which — unlike earlier gas- and liquid-state systems — may represent the future of quantum computing because they can be easily scaled up in size.

Light Created from a Vacuum

• December, 2011

The Casimir Effect Observed in Superconducting Circuit Scientists at Chalmers have succeeded in creating light from vacuum — observing an effect first predicted over 40 years ago. In an innovative experiment, the scientists have managed to capture some of the photons that are constantly appearing and disappearing in the vacuum. The experiment is based on one of the most counterintuitive, yet, one of the most important principles in quantum mechanics: that vacuum is by no means empty nothingness. In fact, the vacuum is full of

Computer Virus Hits U.S. Drone Fleet

• October, 2011

A computer virus has infected the cockpits of America’s Predator and Reaper drones, logging pilots’ every keystroke as they remotely fly missions over Afghanistan and other warzones. The virus, first detected nearly two weeks ago by the military’s Host-Based Security System, has not prevented pilots at Creech Air Force Base in Nevada from flying their missions overseas. Nor have there been any confirmed incidents of classified information being lost or sent to an outside source. But the virus has resisted multiple efforts to remove it

Mike Biddle: We can recycle plastic

• October, 2011

Get sustainable! Share this video with everyone who might be interested in changing their environment. Less dependence on oil for plastic goods Less weight on the shoulders of third world countries Less CO2 emission More closed cycles Of course one doesn’t change the world by only this, we have to keep in mind to: Change the way we live Consume only what we need Remember we can achieve anything we want when we put our minds together

Faster-than-light neutrino claim bolstered

• September, 2011

Representatives from the OPERA collaboration spoke in a seminar at CERN today, supporting their astonishing claim that neutrinos can travel faster than the speed of light. The result is conceptually simple: neutrinos travelling from a particle accelerator at CERN in Switzerland arrived 60 nanoseconds too early at a detector in the Gran Sasso cavern in Italy. And it relies on three conceptually simple measurements, explained Dario Autiero of the Institute of Nuclear Physics in Lyon: the distance between the labs, the time the neutrinos left
