Long-distance quantum communication gets closer as physicists increase light storage efficiency by an order of magnitude

Monday, March 1, 2010 - 09:28 in Physics & Chemistry

(PhysOrg.com) -- In a new demonstration of reversible light storage, physicists have achieved storage efficiencies of more than a magnitude greater than those offered by previous techniques. The new method could be useful for designing quantum repeaters, which are necessary for achieving long-distance quantum communication.
