Bell nonlocality with intensity information only
(American Physical Society, 2020-09-01)
We address the problem of detecting bipartite Bell nonlocality whenever the only experimental information are the intensities produced in each run of the experiment by an unknown number of particles. We point out that this ...

General Bayesian theories and the emergence of the exclusivity principle
(American Physical Society, 2020-10-05)
We address the problem of reconstructing quantum theory from the perspective of an agent who makes bets about the outcomes of possible experiments. We build a general Bayesian framework that can be used to organize the ...

Tracking the dynamics of an ideal quantum measurement
(American Physical Society, 2020-02-25)
The existence of ideal quantum measurements is one of the fundamental predictions of quantum mechanics. In theory, an ideal measurement projects a quantum state onto the eigenbasis of the measurement observable, while ...

Experimental certification of an informationally complete quantum measurement in a device-independent protocol
(Optical Society of America, 2020-02)
Minimal informationally complete positive operator-valued measures (MIC-POVMs) are special kinds of measurement in quantum theory in which the statistics of their d2-outcomes are enough to reconstruct any d-dimensional ...
