摘要

Abstract

Quantum channels in free-space

an essential prerequisite for fundamental tests of quantum mechanics and quantum technologies in open space

have so far been based on direct line-of-sight because the predominant approaches for photon-encoding

including polarization and spatial modes

are not compatible with randomly scattered photons. Here we demonstrate a novel approach to transfer and recover quantum coherence from scattered

non-line-of-sight photons analyzed in a multimode and imaging interferometer for time-bins

combined with photon detection based on a 8 × 8 single-photon-detector-array. The observed time-bin visibility for scattered photons remained at a high 95% over a wide scattering angle range of −45

to +45

while the individual pixels in the detector array resolve or track an image in its field of view of ca. 0.5°. Using our method

we demonstrate the viability of two novel applications. Firstly

using scattered photons as an indirect channel for quantum communication thereby enabling non-line-of-sight quantum communication with background suppression

and secondly

using the combined arrival time and quantum coherence to enhance the contrast of low-light imaging and laser ranging under high background light. We believe our method will instigate new lines for research and development on applying photon coherence from scattered signals to quantum sensing

imaging

and communication in free-space environments.
