The Leggett-Garg Inequalities and No-Signalling in Time: A Quasi-Probability Approach
J. J. Halliwell
The Leggett-Garg (LG) inequalities were proposed in order to assess whether sets of pairs of sequential measurements on a single quantum system can be consistent with an underlying…

A self-adjoint arrival time operator inspired by measurement models
J. J. Halliwell, J. Evaeus, J. London +1
We introduce an arrival time operator which is self-adjoint and, unlike previously proposed arrival time operators, has a close link to simple measurement models. Its spectrum lead…
