Abstract

Optical quantum information processing requires individual photons prepared in well defined quantum states. For high brightness, the key ingredient is a crystal with suitable nonlinear optical properties. The authors identify a family of four crystal systems that yield single photons of significantly higher spectral purity than those from the familiar PPKTP crystal. Furthermore, the wavelengths of these photons may be tuned in a wide band around 1550 nm, ideally matched to current telecommunication protocols.
