Interference contrast in multisource few-photon optics

Abstract

Many recent experiments employ several parametric down-conversion (PDC) sources to get multiphoton interference. Such interference has applications in quantum information. We study here how effects due to photon statistics, misalignment and partial distinguishability of the PDC pairs originating from different sources may lower the interference contrast in multiphoton experiments.

Multiphoton interferometry

Daniel M. Greenberger

Recent theoretical work has shown that there is an intrinsic difference in the nature of the information one can obtain from one-photon, two-photon, and multi-photon interference experiments. Using parametric down conversion, many laboratories have recently performed two-photon interference experiments. We shall discuss these and some proposals for three-photon interferometers and shall point out the kind of non-classical information one could hope to attain from such devices.

Photon bunching and multiphoton interference in parametric down-conversion

Z. Y. Ou, June‐Koo Kevin Rhee, L. J. Wang

A number of multiphoton interference schemes involving independent fields from parametric down-conversion are analyzed. They include fourth-order (two-photon) interference between two fields from two independent parametric down-conversion processes, interference with two independent single photon Fock states (produced by gated parametric down-conversion), and quantum state teleportation and entanglement swapping. It is shown that the visibility in these interference experiments is related to a quantity that is responsible for the photon bunching effect in one of the fields (signal or idler) from the parametric down-conversion process. Besides the two-photon interference schemes, a four-photon interference scheme is discussed where we consider four-photon partition at a beamsplitter. It is found that probability distribution of the partition is dramatically changed by four-photon interference of six paths and the four-photon effect also depends on the same quantity responsible for photon bunching. We will discuss the difference between two-photon interference and four-photon interference.

Optimizing spontaneous parametric down-conversion photon sources for boson sampling

Reinier van der Meer, Jelmer J. Renema, Benjamin Brecht +2 more

An important open challenge in quantum information processing is to demonstrate a quantum device outperforming a classical computer. One of the most promising ways is by sending single photons through a passive linear-optical network, and sampling their output distribution [1]. However, this requires the nontrivial generation of many spectrally pure (indistinguishable) single photons. Most importantly, -spectral distinguishability reduces the visibility of quantum interference of the photons, but can be mitigated by filtering at the cost of optical losses. Unfortunately, losses are also detrimental to quantum interference. We recently quantified the combined role of spectral imperfections and loss in a multiphoton interference experiment [2]. We now apply these results to the problem of constructing spontaneous parametric down-conversion sources. In particular, we investigate the optimal filter bandwidth for different sources and optimize the down-conversion crystal parameters. Our results show that demonstrating a quantum advantage using photonics is difficult, but possible

Multiphoton etanglement: production and applications

Marek Żukowski

Some new experiments leading to observation of multi-photon entanglement will be presented. They utilize multi-pair emissions in a down-conversion crystal. In configurations that avoid interferometric overlaps this leads to a high visibility multi-photon interference. General theoretical results concerning the influence of photon statistics and distinguishability on the interference effects in such experiments is be given. Methods of detection of entanglement in multi-qubit systems, via Bell's theorem and a non-linear generalization of entanglement witnesses, will be presented. Finally it will be shown that multi-photon entanglement can be applied to reduce of communication complexity of some computational tasks.

MULTI-PHOTON INTERFERENCE AND TEMPORAL DISTINGUISHABILITY OF PHOTONS

Z. Y. Ou

A number of recent interference experiments involving multiple photons are reviewed. These experiments include generalized photon bunching effects, generalized Hong-Ou-Mandel interference effects and multi-photon interferometry for demonstrations of multi-photon de Broglie wavelength. The multi-photon states used in these experiments are from two pairs of photons in parametric down-conversion. We find that the size of the interference effect in these experiments, characterized by the visibility of the interference pattern, is governed by the degree of distinguishability among different pairs of photons. Based on this discovery, we generalize the concept of multi-photon temporal distinguishability and relate it to a number of multi-photon interference effects. Finally, we make an attempt to interpret the coherence theory by multi-photon interference via the concept of temporal distinguishability of photons.

Quantum optics experiments with single photons for undergraduate laboratories

Enrique J. Galvez, M. Beck

We present new results of interference experiments for undergraduates that underscore the quantum nature of the light. The experiments use parametric down-conversion to generate pairs of correlated photons. The experiments involve one- and two-photon interference schemes that rely on first and second-order coherence effects. They can be used as a complement to teaching quantum mechanics or quantum optics.
