Optical Quantum Memory Designed
From Technology Review, Optical Quantum Memory Designed: "The researchers' quantum transponder design calls for encoding pairs of quantum bits in sets of four photons in such a way that the two qubits can be read even if one of the four photons is lost. Qubits would be sent into a fiber loop and a simple quantum computer would correct for errors caused by photons being absorbed by the fiber. The design includes a device to generate single photons to replace lost photons."
