Stochastic resetting produces finite pairwise concurrence in the steady state of periodically driven XY and Rydberg spin chains, with a critical rate below which it vanishes and an optimal rate at which it peaks.
Driven non-Hermitian systems show an informational Mpemba effect where more mixed initial states reach unit-purity steady states faster than less mixed ones through collective dissipation.
A theorem identifies ignorable terms in time-independent Hamiltonians for local phenomena in qubit systems and reveals emergent coupling from non-commutativity when the theorem's condition fails.
Loss-induced phases in auxiliary cavities create asymmetric interference, yielding tunable nonreciprocal couplings and entanglement between remote transmon qubits.
