Query: Quantum Light Detection and Ranging   Single-photon light detection and ranging (LiDAR) is a key technology for
depth imaging through complex environments. Despite recent advances, an open
challenge is the ability to isolate the LiDAR signal from other spurious
sources including background light and jamming signals. Here we show that a
time-resolved coincidence scheme can address these challenges by exploiting
spatiotemporal correlations between entangled photon pairs. We demonstrate that
a photon-pair-based LiDAR can distill desired depth information in the presence
of both synchronous and asynchronous spurious signals without prior knowledge
of the scene and the target object. This result enables the development of
robust and secure quantum LiDAR systems and paves the way to time-resolved
quantum imaging applications.
