Heralded Single Photons for Holography

Abstract

We introduce holographic concept based on heralded single photons. The developed quantum approach can extract holographic information even in situations when classical approach fails to detect the information.

Holography of a Photon Without its Detection

Single photon holographic methods would aid several applications that raised with recent advances in quantum technologies. Our method records single photon holograms without detecting the photon itself thanks to the concept of induced coherence.

Quantum Holography with Heralded Single-Photon Source

Denis Abramović, Nazif Demoli, Mario Stipčević +1 more

Quantum imaging usually refers to imaging that takes advantage of quantum entanglement to obtain results beyond the classically achievable limits [1]. Various complex experimental setups are used to obtain quantum images, and even more complex experimental setups are used when the goal is to record and retrieve the phase information of the object. Classical holography offers the possibility to record and retrieve phase information from a hologram [2]. However, in low-light conditions, a major challenge is to record images with a high signal-to-noise ratio. Classical schemes [3]–[5], of course, do not aim to demonstrate the quantum properties of the experiments, and quantum schemes [6]–[8] rely on complex preparation of the light beam and do not necessarily provide an advantage for holographic imaging. To date, no simple quantum scheme with quantum advantage has been developed for low-light holographic imaging.

Quantum holography with single-photon states

Denis Abramović, Nazif Demoli, Mario Stipčević +1 more

The retrieval of the phase with single-photon states is a fundamentally and technically challenging endeavor. Here we report an experimental realization of hologram recordings with heralded single-photon illumination and continuous observation of photon statistics. Thereby, we demonstrate the basic principle of holography with single-photon states which cannot be described with the classical wave theory. Under conditions with illumination more than 200 times weaker than the noise of the detector, a hologram (interferogram) recorded with a heralded single-photon source revealed an object not visible with nonheralded illumination and slightly higher intensity. The dramatic improvement in retrieval of amplitude and phase information achieved with the heralded single-photon source can be explained by the strong suppression of noise due to the nonclassical temporal correlation between twin photons and the small coincidence time window. The method could be useful for recording and retrieving amplitude and phase information in the presence of strong noise, for covert imaging, and for imaging of photosensitive biological and material samples.

Entanglement-enabled quantum holography

Hugo Defienne, Bienvenu I. Ndagano, Ashley Lyons +1 more

We introduce a holographic imaging concept that is conditioned on photonic entanglement. We show that entanglement-encoded phase images can be retrieved through dynamic phase disorder and in the presence of classical noise, with practical advantage over classical holography.

Quantum holography

Ayman F. Abouraddy, Bahaa E. A. Saleh, Alexander V. Sergienko +1 more

We propose to make use of quantum entanglement for extracting holographic information about a remote 3-D object in a confined space which light enters, but from which it cannot escape. Light scattered from the object is detected in this confined space entirely without the benefit of spatial resolution. Quantum holography offers this possibility by virtue of the fourth-order quantum coherence inherent in entangled beams.

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.
