Positive-Operator-Valued Time Observable in Quantum Mechanics

arXiv:quant-ph/9611015 · doi:10.1007/BF02435757

Abstract

We examine the longstanding problem of introducing a time observable in Quantum Mechanics; using the formalism of positive-operator-valued measures we show how to define such an observable in a natural way and we discuss some consequences.
