Description

This proposal develops a robust low size weight and power quantum entangled light source based on time-frequency encoded states. This configuration mitigates the phase stabilization requirements inherent in more conventional coherent quantum systems. An important aspect of the source is nonlinear optic conversion from a relatively short wavelength single photon source to a longer wavelength for low loss transmission over fibers or through a free space optical link. These elements typically require tight temperature control and can account for a substantial portion of the size weight and power budget for the source. This proposal integrates highly efficient and temperature tolerant nonlinear conversion components within the light source. Temperature tolerant design has the potential to minimize or even eliminate temperature control requirements, greatly reducing the size weight and power normally associated with tight temperature control.
