1. A quantum transduction system configured to transfer individual quantum states, the system including a cryogenically cooled piezoelectric, resonant electro-mechanical interface coupling device configured to operate at a quantum level, such that quantum information can be distinguished from background noise;
and in which the system includes a pulsed drive laser converting between a mechanical mode and a photon mode whilst preserving quantum coherence, in which the drive laser is a red-detuned laser configured to result in anti-Stokes scattering.
