Abstract

Single-photon quantum computing Single photons are excellent quantum information carriers, but current schemes for preparing, processing and measuring them are inefficient. This paper introduces a process termed coherent photon conversion that could provide a new way to generate and process complex multiquanta states for photonic quantum information applications. The new scheme is not restricted to optical systems, and could also function in optomechanical, electromechanical and superconducting systems that exhibit even stronger intrinsic nonlinearities.
