Complementary quantum time distributions from a single operational protocol

Using a single quantum-measurement protocol, the author obtains two complementary time distributions: the time-of-flow distribution tracks transitions or probability flow, whereas the quantum stroboscopic distribution tracks occupation or presence. Applied to tunneling, their contrasting behavior provides an operational interpretation of the Hartman effect, in which tunneling delay appears to saturate as a barrier widens.

The authors show that a simple arithmetic condition governing the spatial configuration of dissipation determines whether edge qubits in a quantum many-body system stably synchronize. This finding shows how the decoherence-free subspaces can dictate long-time dynamics.
