An expression for the quantum time of arrival based on the current density is discussed and justified operationally by means of complex potentials that absorb the incoming wave in a finite distance without reflection or transmission. Previous arguments denying the possibility of defining the time of
The concept and the formalization of the arrival time in quantum mechanics are discussed. Different approaches based on trajectories, quantization rules, time operators, phase-space techniques, renewal equations or operational procedures are reviewed or proposed. Open questions and loose ends are po
for a set of unbounded non-commuting operators. Connections with quantum mechanics are discussed.
It is shown that the interpretation of quantum mechanics as a theory describing systems for which their propositions are always valid or not leads t o a contradiction within the theory. The proof does not depend on any specific property of measurements, but only the usual description of ensembles of
