Quantcast

Researchers at the Georgia Institute of Technology have made advances in three key elements needed for quantum information systems and reported the findings Sept. 26 in the journal Nature Physics, and in a manuscript submitted for publication in the journal Physical Review Letters. The research was sponsored by the Air Force Office of Scientific Research, the Office of Naval Research and the National Science Foundation. The advances include:

• Development of an efficient, low-noise system for converting photons carrying quantum information at infrared wavelengths to longer wavelengths suitable for transmission on conventional telecommunications systems.

• A significant improvement in the length of time that a quantum repeater – which would be necessary to transmit the information – can maintain the information in memory.

• An efficient, low-noise system able to convert photons of telecom wavelengths back to infrared wavelengths. Such a system would be necessary for detecting entangled photons transmitted by a quantum information system.
