Abstract
Section titled āAbstractāIt is proposed that the ground-state manifold of the neutral nitrogen-vacancy\ncenter in diamond could be used as a quantum two-level system in a\nsolid-state-based implementation of a broadband, noise-free quantum optical\nmemory. The proposal is based on the same-spin $\Lambda$-type three-level\nsystem created between the two E orbital ground states and the A$_1$ orbital\nexcited state of the center, and the cross-linear polarization selection rules\nobtained with the application of transverse electric field or uniaxial stress.\nPossible decay and decoherence mechanisms of this system are discussed, and it\nis shown that high-efficiency, noise-free storage of photons as short as a few\ntens of picoseconds for at least a few nanoseconds could be possible at low\ntemperature.\n
