Certifying Nonclassical Behavior for Negative Keldysh Quasiprobabilities

Author(s): Patrick P. Potts
We introduce an experimental test for ruling out classical explanations for the statistics obtained when measuring arbitrary observables at arbitrary times using individual detectors. This test requires some trust in the measurements, represented by a few natural assumptions on the detectors. In qua...
