"Time and frequency (TF) encoding in quantum states of light is a promising paradigm for quantum information networks in the near future. This is largely due to the high information capacity provided by TF modes of light, and their compatibility with both… Read More
OMQ Seminar: Proof-of-Principle Laboratory Demonstration of Long-Baseline Interferometric Imaging Using Distributed Single-Photons as a Non-local Oscillator
