Observing quantum coherence from photons scattered in free-space

S. Sajeed and T. Jennewein

This groundbreaking research by Shihan Sajeed and Thomas Jennewein presents a pioneering method to transfer and recover quantum coherence from scattered photons, achieving an impressive 95% time-bin visibility across varied scattering angles. This innovation paves the way for non-line-of-sight quantum communication and improves low-light imaging contrast.

Abstract

This paper demonstrates a novel approach to transfer and recover quantum coherence from scattered photons, overcoming limitations of previous methods that relied on direct line-of-sight. Using a multimode imaging interferometer and a single-photon detector array, the researchers achieved high time-bin visibility (95%) over a wide scattering angle range. This method enables non-line-of-sight quantum communication and enhances low-light imaging contrast.
