Title: Paradox with Phase-Coupled Interferometers
Authors: Saba Etezad-Razavi and Lucien Hardy
Abstract summary: A pair of interferometers can be coupled by allowing one path from each to overlap such that if the particles meet in this overlap region, they annihilate. We show that phase-coupled interferometers exhibit the same apparent paradox as the annihilation-coupled interferometers, though in a curiously dual manner.

Abstract: A pair of interferometers can be coupled by allowing one path from each to overlap such that if the particles meet in this overlap region, they annihilate. It was shown by one of us over thirty years ago that such annihilation-coupled interferometers can exhibit apparently paradoxical behaviour. More recently, Bose et al. and Marletto and Vedral have considered a pair of interferometers that are phase-coupled (where the coupling is through gravitational interaction). In this case one path from each interferometer undergoes a phase-coupling interaction. We show that these phase-coupled interferometers exhibit the same apparent paradox as the annihilation-coupled interferometers, though in a curiously dual manner.

Realizing a spatially correlated lattice interferometer [8.81055904289318]
Atom interferometers provide a powerful tool for measuring physical constants and testifying fundamental physics with unprecedented precision. Here, we report on realizing a Ramsey-Bord'e interferometer of coherent matter waves dressed by a moving optical lattice in the gravity direction. Our findings agree well with theoretical simulations, paving the way for high-precision interferometry with ultracold atoms.

We implement two types of matter-wave interferometers using trapped Bose-condensed Feshbach molecules. In each case, we focus on investigating interaction effects and their implications for the performance.

Entanglement-induced collective many-body interference [62.22849132943891]
We propose an interferometric setting through which N-particle interference can be observed, while any interference of lower orders is strictly suppressed. We experimentally demonstrate this effect in a four-photon interferometer, where the interference is nonlocal, in principle. A joint detection of all four photons identifies a high-visibility interference pattern varying as a function of their collective four-particle phase, a genuine four-body property.

Quantum fluctuations in the small Fabry-Perot interferometer [77.34726150561087]
We study the small, of the size of the order of the wavelength, interferometer with the main mode excited by a quantum field from a nano-LED or a laser. We find the field and the photon number fluctuation spectra inside and outside the interferometer. Results help the study, design, manufacture, and use small elements of quantum optical integrated circuits.

Two-colour spectrally multimode integrated SU(1,1) interferometer [77.34726150561087]
We develop and investigate an integrated multimode two-colour SU (1,1) interferometer that operates in a supersensitive mode. By ensuring a proper design of the integrated platform, we suppress dispersion and thereby significantly increase the visibility of the interference pattern. We demonstrate that such an interferometer overcomes the classical phase sensitivity limit for wide parametric gain ranges, when up to $3*104$ photons are generated.

We investigate the interference setup claimed to reveal the quantum pigeonhole effect. It is a claim that it is possible that three parties travel across a two-path interferometer, but no pair of them share a path.

Quantum asymmetry and noisy multi-mode interferometry [55.41644538483948]
Quantum asymmetry is a physical resource which coincides with the amount of coherence between the eigenspaces of a generator. We show that the asymmetry may emphincrease as a result of a emphdecrease of coherence inside a degenerate subspace.
