Abstract:
We present an advanced quantum ghost imaging (QGI) setup that enables low-noise, three-dimensional imaging and ranging of distant objects. A key technical innovation is asynchronous detection by independent single photon detectors, which significantly simplifies existing setups and allows imaging at arbitrary distances. Recent experimental results demonstrate low-noise imaging and efficient object ranging. An important quantum advantage with regard to secure active sensing is indistinguishability from background noise for external parties.
