Efficient Simulation of Nonreciprocal Many-body Physics via Quantum Feedback
Kseniia Vodenkova, Andrew Pocklington, Fan Yang +3
We present a scheme to efficiently simulate nonreciprocal many-body spin models using a non-Markovian open system. Our scheme utilizes a single quantum emitter coupled to a wavegui…
Insights into decohered critical states using an exact solution to matchgate circuits with Pauli noise
Andrew Pocklington, Aashish A. Clerk
The fate of non-trivial many-body states subject to decoherence is of both fundamental and practical interest. Here, we demonstrate a new analytic technique that allows for an exac…
Efficient simulation of non-trivial dissipative spin chains via stochastic unraveling
Andrew Pocklington, Aashish A. Clerk
We present a new technique for efficiently simulating (in polynomial time) a class of one-dimensional (1D) dissipative spin chains that, when mapped to fermions, have quadratic Ham…
Accelerating Dissipative State Preparation with Adaptive Open Quantum Dynamics
Andrew Pocklington, Aashish A. Clerk
A wide variety of dissipative state preparation schemes suffer from a basic time-entanglement tradeoff: the more entangled the steady state, the slower the relaxation to the steady…
Non-Gaussian generalized two-mode squeezing: applications to two-ensemble spin squeezing and beyond
Mikhail Mamaev, Martin Koppenhöfer, Andrew Pocklington +1
Bosonic two-mode squeezed states are paradigmatic entangled Gaussian states that have wide utility in quantum information and metrology. Here, we show that the basic structure of t…
Universal Time-Entanglement Trade-off in Open Quantum Systems
Andrew Pocklington, Aashish A. Clerk
We demonstrate a surprising connection between pure steady state entanglement and relaxation timescales in an extremely broad class of Markovian open systems, where two (possibly m…
Stability via symmetry breaking in interacting driven systems
Andrew Pocklington, Aashish A. Clerk
Photonic and bosonic systems subject to incoherent, wide-bandwidth driving cannot typically reach stable finite-density phases using only non-dissipative Hamiltonian nonlinearities…
Exact Results for a Boundary-Driven Double Spin Chain and Resource-Efficient Remote Entanglement Stabilization
Andrew Lingenfelter, Mingxing Yao, Andrew Pocklington +4
We derive an exact solution for the steady state of a setup where two -coupled -qubit spin chains (with possibly non-uniform couplings) are subject to boundary Rabi drives,…
Dissipative Pairing Interactions: Quantum Instabilities, Topological Light, and Volume-Law Entanglement
Andrew Pocklington, Yu-Xin Wang, Aashish A. Clerk
We analyze an unusual class of bosonic dynamical instabilities that arise from dissipative (or non-Hermitian) pairing interactions. We show that, surprisingly, a completely stable…
A dual-element, two-dimensional atom array with continuous-mode operation
Kevin Singh, Shraddha Anand, Andrew Pocklington +2
Quantum processing architectures that include multiple qubit modalities offer compelling strategies for high-fidelity operations and readout, quantum error correction, and a path f…
Stabilizing volume-law entangled states of fermions and qubits using local dissipation
Andrew Pocklington, Yu-Xin Wang, Yariv Yanay +1
We analyze a general method for the dissipative preparation and stabilization of volume-law entangled states of fermionic and qubit lattice systems in 1D (and higher dimensions for…
