Bath-induced deviations from Gibbs statistics for strongly interacting oscillators
Felipe Recabal, Adrian E. Rubio Lopez, Johannes Schachenmayer +1
The Redfield quantum master equation is widely used to study the dynamics of interacting sub-systems that are weakly coupled to baths. Redfield dynamics under secular approximation…
Efficiency of classical simulations of a noisy Grover algorithm
Raphaël Menu, Johannes Schachenmayer
We analyze the modification of entanglement dynamics in the Grover algorithm when the qubits are subjected to single-qubit amplitude-damping or phase-flip noise. We compare quantum…
Non-unitarity maximizing unraveling of open quantum dynamics
Ruben Daraban, Fabrizio Salas-Ramírez, Johannes Schachenmayer
The dynamics of many-body quantum states in open systems is commonly numerically simulated by unraveling the density matrix into pure-state trajectories. In this work, we introduce…
Open quantum dynamics with variational non-Gaussian states and the truncated Wigner approximation
Liam J. Bond, Bas Gerritsen, Jiří Minář +3
We present a framework for simulating the open dynamics of spin-boson systems by combining variational non-Gaussian states with a quantum trajectories approach. We apply this metho…
