(PhysOrg.com) -- Using photons instead of electrons to transmit information could lead to faster and more secure ways to communicate, among other advantages. Now a team of physicists has taken another step toward realizing quantum photonic technologies by demonstrating how to quickly manipulate single photons at the same wavelengths used in existing optical telecommunications networks. The ability to control a photon’s path and polarization in the time of a few nanoseconds could allow photonic circuits to be integrated with existing optical telecom networks, leading to significant improvements.
