Quantum 'paparazzi' film photons in the act of pairing up

April 22, 2015 2:30 pm | by Faculty of Physics University of Warsaw | News | Comments

In the quantum world of light, being distinguishable means staying lonely. Only those photons that are indistinguishable can wind up in a pair, through what is called Hong-Ou-Mandel interference. This subtle quantum effect has been successfully imaged for the first time by ...

Drexel materials scientists putting a new spin on computing memory

April 22, 2015 2:22 pm | by Drexel University | News | Comments

Ever since computers have been small enough to be fixtures on desks and laps, their central processing has functioned something like an atomic Etch A Sketch, with electromagnetic fields pushing data bits into place to encode data. Unfortunately, the same drawbacks ...

Vehicle cost, lack of consumer information hinder purchases of plug-in electric vehicles
