Quantum Interface Based on a Non-Hermitian Magnon-Photon Beamsplitter

Abstract

We report an atom-light beamsplitter-type interface, in which flying photons and stored atomic coherence can be transformed reversibly. The degree of Hermiticity of this interface can alter the atom-photon quantum interference from bosonic to fermion-like.

Quantum Interference between Photons and Single Quanta of Stored Atomic Coherence

Xingchang Wang, Jianmin Wang, Zhiqiang Ren +4 more

Essential for building quantum networks over remote independent nodes, the indistinguishability of photons has been extensively studied by observing the coincidence dip in the Hong-Ou-Mandel interferometer. However, indistinguishability is not limited to the same type of bosons. For the first time, we hereby observe quantum interference between flying photons and a single quantum of stored atomic coherence (magnon) in an atom-light beam splitter interface. We demonstrate that the Hermiticity of this interface determines the type of quantum interference between photons and magnons. Consequently, not only the bunching behavior that characterizes bosons is observed, but counterintuitively, fermionlike antibunching as well. The hybrid nature of the demonstrated magnon-photon quantum interface can be applied to versatile quantum memory platforms, and can lead to fundamentally different photon distributions from those occurring in boson sampling.

Non-Hermitian Magnon-Photon Interference in an Atomic Ensemble

Rong Wen, Chang‐Ling Zou, Xinyu Zhu +4 more

The interference of photons in a lossy beam splitter (BS) exhibits anticoalescence, which is surprising for bosons. Such a non-Hermitian system involving open quantum dynamics is of particular interest for quantum information processing and metrology. The Hermiticity of photonic devices is generally fixed according to the material, but is controllable at the interface of photons and atomic systems. Here, we demonstrate a tunable non-Hermitian BS for the interference between traveling photonic and localized magnonic modes. The crossover from a Hermitian to a non-Hermitian magnon-photon BS is achieved by controlling the coherent and incoherent interaction mediated by the excited levels of atoms, which is reconfigurable via the detuning of a control laser. A correlated interference pattern between the photons and magnons is demonstrated by such a non-Hermitian BS. Our system has the potential to operate with photons and magnons at the single-quanta level, and it provides a versatile quantum interface for studying the non-Hermitian quantum physics and parity-time symmetry.

Tunable magnon-photon beam-splitter based on a cold atomic cloud

J. F. Chen

The flying photons are stored into an atomic cloud as “magnons”, i.e., the ground-state atomic excitation. A tunable magnon-photon beam-splitter, which induces interference from Hermitian to non-Hermitian, is demonstrated through a cold atomic cloud.

A Quantum Light-Matter Beamsplitter in Diamond

Duncan G. England, Khabat Heshami, Philip J. Bustard +4 more

A quantum memory can be viewed as a light-matter beam-splitter, mapping a photon to a superposition of the output optical mode and stored mode. We use this mechanism to demonstrate non-classical one-photon and two-photon interference.

Conversion of Laser Light into (Anti)-Bunched Light in an Atom-Based Two-Photon Interferometer

Martin Cordier, Max Schemmer, Philipp Schneeweiß +2 more

Interference phenomena are at the origin of many intriguing effects in physics, in particular in the field of quantum optics. Here, we present a novel type of interferometer, which realizes interference in the two-photon component of an incoming laser light. As a consequence, it converts the laser light into a stream of single photons or photonpairs. In this two-photon interferometer, the beam splitters and the phase shifter of the interferometer are realized using cold atoms, which are trapped and optically interfaced with an optical nanofiber (see Fig. 1.a).

Quantum Interference between Nonidentical Single Particles

Keyu Su, Yi Zhong, Shanchao Zhang +5 more

Quantum interference between identical single particles reveals the intrinsic quantum statistic nature of particles, which could not be interpreted through classical physics. Here, we demonstrate quantum interference between nonidentical bosons using a generalized beam splitter based on a quantum memory. The Hong-Ou-Mandel type interference between single photons and single magnons with high visibility is demonstrated, and the crossover from the bosonic to fermionic quantum statistics is observed by tuning the beam splitter to be non-Hermitian. Moreover, multiparticle interference that simulates the behavior of three fermions by three input photons is realized. Our work extends the understanding of the quantum interference effects and demonstrates a versatile experimental platform for studying and engineering quantum statistics of particles.
