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 …

Memory or time-non-local effects in open quantum dynamics pose theoretical as well as
practical challenges in the understanding and control of noisy quantum systems. While there …

We propose a method to realize microwave-activated CZ gates between two remote spin
qubits in quantum dots using an offset-charge-sensitive transmon coupler. The qubits are …

Quantum error mitigation, a data processing technique for recovering the statistics of target
processes from their noisy version, is a crucial task for near-term quantum technologies …

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 …
