Tensor network methods for non-perturbative dynamics of open quantum systems
Thibaut Lacroix, Adam Burgess, Nicola Lorenzoni +11
The description of open quantum system dynamics beyond the perturbative treatment (usually associated with Markovian master equations) is a computationally challenging task due to…
Revisiting crossed-correlated baths in open quantum systems simulated by HEOM or T-TEDOPA
Brieuc Le Dé, Etienne Mangaud, Alex W. Chin +1
Excited-state dynamics of open quantum systems is analyzed by the hierarchical equations of motion (HEOM) or the thermalized time-evolving density operator with orthogonal polynomi…
A comparison of different master equations for driven-dissipative dynamics in composite quantum systems: Dispersive readout in structured electromagnetic environments
Prakritish Gogoi, Angela Riva, Ãmile Cochin +1
Driven-dissipative qubit-resonator dynamics, which are the basis of most dispersive superconducting qubit measurement schemes, are often modeled with Lindblad master equations buil…
First-principles study of dispersive readout in circuit QED
Angela Riva, Prakritish Gogoi, Nicolas Gheeraert +4
The speed and fidelity of dispersive readout of superconducting qubits should improve by increasing the amplitude of the measurement drive. Experiments show, however, that beyond s…
Efficient construction of time-invariant process tensors for simulating high-dimensional non-Markovian open quantum systems
Ãmile Cochin, Jonathan Keeling, Brendon W. Lovett +1
Numerical methods for obtaining exact dynamics of non-Markovian open quantum systems are mostly limited to either small systems or to short-time evolution only. Here, we propose a…
Connectivity matters: Impact of bath modes ordering and geometry in open quantum system simulation with Tensor Network States
Thibaut Lacroix, Brendon W. Lovett, Alex W. Chin
Being able to study the dynamics of quantum systems interacting with several environments is important in many settings ranging from quantum chemistry to quantum thermodynamics, th…
