Dissipation in mechanics, optics, acoustics, and electronic circuits is nowadays recognized
to be not always detrimental but can be exploited to achieve non-Hermitian topological …

For the efficient simulation of open quantum systems, we often use quantum jump
trajectories given by pure states that evolve stochastically to unravel the dynamics of the …

We study experimentally and numerically the noisy evolution of multipartite entangled states,
focusing on superconducting qubit devices accessible via the cloud. We find that a valid …

We describe temporally correlated noise processes that influence the idle evolution of a
superconducting transmon qubit. To model the composite qubit-environment system we use …

The pseudomode framework provides an exact description of the dynamics of an open
quantum system coupled to a non-Markovian environment. Using this framework, the …

A relevant problem in the theory of open quantum systems is the lack of complete positivity
of dynamical maps obtained after weak-coupling approximations, a famous example being …

Non-Markovian noise can be a significant source of errors in superconducting qubits. We
develop gate sequences utilising mirrored pseudoidentities that allow us to characterise and …

Quantum systems are unavoidably open to their surrounding degrees of freedom. The
theory of open quantum systems is thus crucial to understanding the fluctuations …

A bstract Quantum scrambling plays an important role in understanding thermalization in
closed quantum systems. By this effect, quantum information spreads throughout the system …

Recently, Nathan and Rudner derived a Gorini-Kossakowski-Sudarshan-Lindblad master
equation from the Redfield equation. The claim is that the level of approximation is equal to …
