Continuously measured quantum systems are characterized by an output current, in the form
of a stochastic and correlated time series, which conveys crucial information about the …

We study the robustness of the evolution of a quantum system against small uncontrolled
variations in parameters in the Hamiltonian. We show that the fidelity susceptibility, which …

The theory of optimal quantum control serves to identify time-dependent control
Hamiltonians that efficiently produce desired target states. As such, it plays an essential role …

The nonequilibrium dynamics of long-range pairing Kitaev model with noiseless/noisy linear
time dependent chemical potential, is investigated in the framework of dynamical quantum …

Noise is ubiquitous in nature, so it is essential to characterize its effects. Considering a
fluctuating Hamiltonian, we introduce an observable, the stochastic operator variance (SOV) …

The mechanism of selectivity in ion channels is still an open question in biology. Recent
studies suggest that the selectivity filter may exhibit quantum coherence, which could help …

All quantum systems are subject to noise from the environment or external controls. This
noise is a major obstacle to the realization of quantum technology. For example, noise limits …

We study how time-dependent energy fluctuations impact the dynamical quantum phase
transitions (DQPTs) following a noisy ramped quench of the transverse magnetic field in a …

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

In open quantum systems theory, reduced models are invaluable for conceptual
understanding and computational efficiency. Adiabatic elimination is a useful model …
