Quantum speed limits across the quantum-to-classical transition
Physical review letters, 2018•APS
Quantum speed limits set an upper bound to the rate at which a quantum system can evolve.
Adopting a phase-space approach, we explore quantum speed limits across the quantum-to-
classical transition and identify equivalent bounds in the classical world. As a result, and
contrary to common belief, we show that speed limits exist for both quantum and classical
systems. As in the quantum domain, classical speed limits are set by a given norm of the
generator of time evolution.
