Title: How single-photon nonlinearity is quenched with multiple quantum emitters: Quantum Zeno effect in collective interactions with $\Lambda$-level atoms
Authors: Alexander N. Poddubny, Serge Rosenblum and Barak Dayan
Abstract summary: We show that the single-photon nonlinearity vanishes with the number of emitters. The mechanism behind this behavior is the quantum Zeno effect, manifested in the slowdown of the photon-controlled dynamics.

Abstract: Single-photon nonlinearity, namely the change in the response of the system as the result of the interaction with a single photon, is generally considered an inherent property of a single quantum emitter. Understanding the dependence of the nonlinearity on the number of emitters is important both fundamentally and practically, as strong light-matter coupling is more readily achieved through collective interactions than with a single emitter. Here, we theoretically consider a system that explores the transition from a single to multiple emitters with a $\Lambda$-level scheme. We show that the single-photon nonlinearity indeed vanishes with the number of emitters. Interestingly, the mechanism behind this behavior is the quantum Zeno effect, manifested in the slowdown of the photon-controlled dynamics.

Violation of Bell inequality by photon scattering on a two-level emitter [4.810881229568956]
Entanglement, the non-local correlations present in quantum systems, is a curious feature of quantum mechanics and the fuel of quantum technology. We show how a single two-level emitter deterministically coupled to light in a nanophotonic waveguide is used to realize genuine photonic quantum entanglement for excitation at the single photon level.

We study the single-photon collective dynamics in a waveguide system consisting of the photon channel with a finite bandwidth and an ensemble of quantum emitters. Our findings lead to the prediction that single-photon collective emissions can be strongly suppressed if the number of excited emitters is much less than the total number of emitters in the system.

We experimentally observe the parity symmetry breaking of an ancillary Xmon artificial atom induced by the field of a lumped-element superconducting resonator.

In this work, we demonstrate experimentally that the two-particle coincidence statistics of two bosons can instead be seamlessly tuned to substantial enhancement. Our findings reveal a new approach to harnessing non-Hermitian settings for the manipulation of multi-particle quantum states.
