A practical polariton laser - Nature Photonics - 2 views

  •  
    One overview about a recent publication (10/06/2014 http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.112.236802) showing room temperature operation of a new type of laser 'discovered' in 2013, the polariton laser. This new type of laser shows extremely low threshold current density - 2 orders of magnitude below Vertical Cavity Surface Emitting Lasers (VCSEL) - and it is believed to become one important component of nanophotonic integrated components.

Why Quantum "Clippers" Will Distribute Entanglement Across The Oceans - 0 views

  •  
    Quantum internet will enable perfectly secure communications, but the technology and means to build the required quantum memories and routers are still many years distant. The proposal here is to store qubits and send them in containers over the oceans. Researchers claim that it is possible to send information at bandwidths measured in teraahertz outperforming the predictions of a quantum router internet. It can be thought in space systems as well. Then the problem is still for how long are we able to store a qubit, without dephasing... PS: As a curiosity, you can find a very interesting book about containers and how in some way they changed our world: Mark Levinson's book 'The Box' http://press.princeton.edu/titles/9383.html Maybe they will do it again

Oculus Rift users to see Moon live through robot - 2 views

  •  
    A group from Carnegie Mellon wants to send a robot to the Moon to beam live pictures of the Moon to Oculus Rift headset users, reported technology reporter Jane Wakefield of the BBC. Andy the robot is intended to swing into action as a robot on a mission to transform education about space.
