Embedding of Time-Delayed Quantum Feedback in a Nonreciprocal Array

  title={Embedding of Time-Delayed Quantum Feedback in a Nonreciprocal Array},
  author={Xin H. H. Zhang and Sabine H. L. Klapp and Anja Metelmann},
Time-delayed quantum feedback is a fast and efficient method to control and stabilize few and many-body quantum systems. However, a proper understanding of such systems stays opaque due to the non-Markovian nature of the feedback protocol. Here, we present a method of encoding time-delayed quantum feedback into a chain of nonreciprocally coupled auxiliary oscillators. Our approach serves as a novel method of introducing time-delayed quantum feedback and provides the advantage of large tunability…

Introduction to quantum non-reciprocal interactions: from non-Hermitian Hamiltonians to quantum master equations and quantum feedforward schemes

These lecture notes from the 2019 Les Houches Summer School on Quantum Information Machines provides a pedagogical introduction to the theory of non-reciprocal quantum interactions and devices. The

Irreversibility, heat and information flows induced by non-reciprocal interactions

We study the thermodynamic properties induced by non-reciprocal interactions between stochastic degrees of freedom in time- and space-continuous systems. We show that, under fairly general

The ITensor Software Library for Tensor Network Calculations

The philosophy behind ITensor, a system for programming tensor network calculations with an interface modeled on tensor diagrams, and examples of each part of the interface including Index objects, the ITensor product operator, tensor factorizations, and tensor storage types are discussed.

Intermittent decoherence blockade in a chiral ring environment

It is shown that decoherence suppression can be intermittently achieved on a limited time scale, without the need for any dark state, when the atom is coupled to a chiral ring environment, leading to a highly non-exponential staircase decay.

Waveguide quantum electrodynamics with superconducting artificial giant atoms

An alternative architecture is used that realizes a giant atom by coupling small atoms to a waveguide at multiple, but well separated, discrete locations, producing tunable atom–waveguide coupling and enabling decoherence-free interactions.

Quantum trajectory theory of few-photon cavity-QED systems with a time-delayed coherent feedback

We describe an efficient approach to modeling cavity quantum electrodynamics (QED) with a time-delayed coherent feedback using quantum trajectory simulations. An analytical set of equations is

Non-Markovian Collective Emission from Macroscopically Separated Emitters.

The collective spontaneous emission rate of the emitters exhibits an enhancement or inhibition beyond the usual Dicke superradiance and subradiance due to self-consistent coherent time-delayed feedback.

Simulation methods for open quantum many-body systems

This work reviews several approaches to simulate open many-body systems and point out the advances made in recent years towards the simulation of large system sizes.
