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…
