Single atom stores quantum information |
May 03, 2011
A powerful quantum computer could be designed with an incredibly tiny memory. Researchers wrote the quantum state of single photons, i.e. particles of light, into a rubidium atom and read it out again after a certain storage time. This technique can be used in principle to design powerful quantum computers and to network them with each other across large distances.
