Ground state cooling of quantum systems via a one-shot measurement
arXiv:1503.04133 · doi:10.1103/PhysRevA.93.032120
Abstract
We prove that there exists a family of quantum systems that can be cooled to their ground states by a one-shot projective measurement on the ancillas coupled to these systems. Consequently, this proof gives rise to the conditions for achieving the one-shot measurement ground-state cooling (OSMGSC). We also propose a general procedure for finding unitary propagators and corresponding Hamiltonians to realize such cooling by means of inverse engineering technique.
