Single Photon Image Discrimination

Abstract

We present experimental results demonstrating image discrimination with a single photon. A multiplexed hologram is used to distinguish between two single photon images with confidence of greater than 93.4% without requiring an ensemble.

Quantum Ghost Image Discrimination with a Single Photon Pair

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.

Discriminating orthogonal single-photon images

Curtis J. Broadbent, Petros Zerom, Heedeuk Shin +2 more

We can encode an image from an orthogonal basis set onto a single photon from a downconverted pair via the use of an amplitude mask. We can then discriminate the image imprinted on the photon from other images in the set using holographic-matched filtering techniques. We demonstrate this procedure experimentally for an image space of two objects, and we discuss the possibility of applying this method to a much larger image space. This process could have important implications for the manipulation of images at the quantum level.

Experimental Implementation of Optimum Unambiguous and Maximum-Confidence Discrimination of Two Single Photon Mixed States

Oliver J. Benson, Gesine A. Steudle, Sebastian Knauer +1 more

We introduce experimental implementations of optimum unambiguous and maximum-confidence discrimination of two mixed states. Linear optics and polarization states of single photons from a true single-photon source based on a semiconductor quantum dot are utilized.

Hologram of a single photon

We experimentally show that the complex transversal wavefunction of the unknown photon can be fully recovered from the spatially-resolved coincidence pattern resulting from its two-photon interference with the reference photon.

Quantum holography with undetected photons

Holography is a versatile tool in optical sensing and imaging. We report on a quantum holography approach that allows to record holograms on the single photon level without recording the photons illuminating the object.
