(Phys.org) -- A team of Chinese physicists has broken the distance record for teleporting qubits, extending it from 16 to 97 kilometers. They did so, as they explain in their paper uploaded to the preprint server arXiv, using the phenomenon known as entanglement.

Feed SubscriptionResearchers create computer simulations of primordial black holes striking the Earth
(PhysOrg.com) -- Black holes have captured the imagination of scientists and amateur enthusiasts for years. The idea of some dark entity out there in the far reaches of space sucking up anything and everything that ventures near with such power and force that even light can’t escape it’s clutches, both enthralls and terrifies. Thus, the idea of one moving close enough to our planet would seem good reason to hit the panic button

(PhysOrg.com) -- Imagine sitting around a conference table with several of your colleagues as you hold an important meeting. Now imagine your boss pulling out what looks like a radar gun for catching speeding motorists and aiming at any of you that speak to long, very nearly instantly causing whoever is speaking to start stuttering then mumbling and then to stop speaking at all

(PhysOrg.com) -- Geraldo Barbosa, professor of electrical engineering and computer science at Northwestern University has posed an interesting challenge. He wonders if the human eye and brain together are capable of actually seeing entangled images. This is not a philosophical question, as he has phrased the query as part of a practical experiment that someone with the proper lab could actually carry out.

(PhysOrg.com) -- Scientists have long been enamored by the gecko’s gravity defying ability to cling to walls and to let go at will, allowing it to walk around sideways, as have Spiderman enthusiasts.

(PhysOrg.com) -- Researchers at D-Wave Systems have carried out a calculation involving 84 qubits on an experimental quantum computer, giving some credence to the plausibility of true quantum computers being created that could vastly surpass the abilities of all those that currently rely on existing technology.

By Eugenie Samuel Reich of Nature magazine The claim that neutrinos can travel faster than light has been given a knock by an independent experiment. On 17 October, the Imaging Cosmic and Rare Underground Signals (ICARUS) collaboration submitted a paper to the preprint server arXiv.org, in which it offered a rebuttal of claims to have clocked subatomic particles called neutrinos traveling faster than the speed of light.

(PhysOrg.com) -- It's been just two weeks since the Oscillation Project with Emulsion-tRacking Apparatus (OPERA) team released its announcement claiming that they have been measuring muon neutrinos moving faster than the speed of light, causing an uproar in the physics community.
