Understanding and utilizing the inner bonds of process tensors
Moritz Cygorek, Erik M. Gauger
Process tensor matrix product operators (PT-MPOs) enable numerically exact simulations for an unprecedentedly broad range of open quantum systems. By representing environment influ…
Tree-like process tensor contraction for automated compression of environments
Moritz Cygorek, Brendon W. Lovett, Jonathan Keeling +1
The algorithm "automated compression of environments" (ACE) [Nat. Phys. 18, 662 (2022)] provides a versatile way of simulating an extremely broad class of open quantum systems. Thi…
Differentiable master equation solver for quantum device characterisation
David L. Craig, Natalia Ares, Erik M. Gauger
Differentiable models of physical systems provide a powerful platform for gradient-based algorithms, with particular impact on parameter estimation and optimal control. Quantum sys…
ACE: A general-purpose non-Markovian open quantum systems simulation toolkit based on process tensors
Moritz Cygorek, Erik M. Gauger
We describe a general-purpose computational toolkit for simulating open quantum systems, which provides numerically exact solutions for composites of zero-dimensional quantum syste…
The role of polaron dressing in superradiant emission dynamics
Julian Wiercinski, Moritz Cygorek, Erik M. Gauger
Cooperative effects of multiple quantum emitters are characterized by transitions via delocalized collective states with altered emission properties due to the existence of inter-e…
Influence of strong molecular vibrations on decoherence of molecular polaritons
Dominic M Rouse, Erik M Gauger, Brendon W Lovett
We derive the transition rates, dephasing rates, and Lamb shifts for a system consisting of many molecules collectively coupled to a resonant cavity mode. Using a variational polar…
