“One of the fundamental issues in physics right now – and for the past many years – is whether or not bosons can form a supersolid phase,” Frédéric Mila tells PhysOrg.com. Mila is a scientist at the Institute of Theoretical ... | |
Classical communication problem solved using quantum entanglement March 11, 2008 | User rating: 4 / 5 after 47 vote(s)
| User comments: 3
One of the problems plaguing classical communication is associated with what is known as the Byzantine agreement. In this problem, messages between three different parties are subject to faulty information. Quantum communication, ... | |
 Weird wave behavior may explain why the whirligig walks in circles March 04, 2008 | User rating: 4.5 / 5 after 56 vote(s)
| User comments: 2
The whirligig beetle is named for its trademark of walking in circles on the surface of water. Upon investigating a new phenomenon of water wave generation, scientists might now understand why. | |

The most recent results from the Antarctic Muon and Neutrino Detector Array, or AMANDA, located a mile under the ice at the South Pole, have yielded the most stringent prediction yet for the highest possible ... | |
Physicists Demonstrate Qubit-Qutrit Entanglement February 26, 2008 | User rating: 4.7 / 5 after 89 vote(s)
| User comments: 2
For the first time, physicists have entangled a qubit with a “qutrit” – the 3D version of the 2D qubit. Qubit-qutrit entanglement could lead to advantages in quantum computing, such as increased security and more efficient ... | |
 Moth eyes may hold key to more efficient solar cells February 22, 2008 | User rating: 4.7 / 5 after 111 vote(s)
| User comments: 4
One of the difficulties with solar power is that solar cells are notoriously inefficient. Some of that inefficiency, says Peng Jiang, is due to the fact that silicon is reflective. Jiang, an assistant professor ... | |
 The Dark Side of Light February 19, 2008 | User rating: 4.5 / 5 after 193 vote(s)
| User comments: 23
Light may not seem very interesting in our everyday lives. But to scientists, light’s properties are a constant source of intrigue. The nature of light as both wave and particle, light as the universal speed ... | |
A 'Golden Channel' for New Physics February 15, 2008 | User rating: 4.1 / 5 after 60 vote(s)
