Quantum ghost imaging using asynchronous detection

Carsten Pitsch, Dominik Walter, Simon Grosse +3 more

We present first results of a novel type of setup for quantum ghost imaging based on asynchronous single photon timing using single photon avalanche diode (SPAD) detectors. This scheme enables photon pairing with arbitrary path length difference and does, therefore, obviate the dependence on optical delay lines of current quantum ghost imaging setups [Nat. Commun.6, 5913 (2015)NCAOBW2041-172310.1038/ncomms6913]. It is also, to our knowledge, the first quantum ghost imaging setup to allow three-dimensional imaging.We present first results of a novel type of setup for quantum ghost imaging based on asynchronous single photon timing using single photon avalanche diode (SPAD) detectors.

3D quantum ghost imaging

Carsten Pitsch, Dominik Walter, Leonardo Gasparini +2 more

We present current results of a novel, to the best of our knowledge, type of setup for quantum ghost imaging based on asynchronous single photon timing using single photon avalanche diode (SPAD) detectors, first presented in [Appl. Opt.60, F66 (2021)APOPAI0003-693510.1364/AO.423634]. The scheme enables photon pairing without fixed delays and, thus, overcomes some limitations of the widely used heralded setups for quantum ghost imaging [Nat. Commun.6, 5913 (2015)NCAOBW2041-172310.1038/ncomms6913]. It especially allows three-dimensional (3D) imaging by direct time of flight methods, the first demonstration of which will be shown here. To our knowledge, it is also the first demonstration of 3D quantum ghost imaging at all.We present current results of a novel, to the best of our knowledge, type of setup for quantum ghost imaging based on asynchronous single photon timing using single photon avalanche diode (SPAD) detectors, first presented in [Appl.

Quantum Ghost Imaging for Remote Sensing

Dominik Walter, Carsten Pitsch, Helge Bürsing

An advanced setup for quantum ghost imaging that features asynchronous detection enables low-noise 3D imaging of distant objects. Recent experimental results show the potential of the setup to outperform classical systems in many aspects.

Quantum secure ghost imaging

Xin Yao, Xu Liu, Wei Zhang +1 more

We propose and experimentally demonstrate a scheme of quantum secure ghost imaging. It realizes information transmission over optical fibers by temporal ghost imaging, and performs the security test by monitoring the entanglement in photon pairs.

Quantum Ghost Image Discrimination with a Single Photon Pair

Mehul Malik, Heedeuk Shin, Petros Zerom +1 more

A quantum ghost imaging scheme is modified to discriminate between two spatially non-overlapping objects using a single pair of entangled photons. The “ghost” image information is extracted by means of holographic filtering and coincidence detection.

Applications of Quantum Entanglement Towards “Ghost” Imaging

Weronika Pach

In this work, pairs of entangled photons are aimed at two spatially separated detectors: the path to one detector contains a physical object, while the path to the second detector does not. Yet, the second detector can be used to create an image of the object, even though none of the photons arriving at that detector have ever interacted with the object! This “ghost” imaging takes advantage of information that is shared between entangled photon pairs. This work aims to explore the underlying principles in a ghost imaging system that utilizes spontaneous parametric down-conversion (SPDC) as the source of entangled photons, with the larger goal of understanding the principles and operation of key parts of the system.In this work, pairs of entangled photons are aimed at two spatially separated detectors: the path to one detector contains a physical object, while the path to the second detector does not.
