Adversarial Information Gain in Non-ideal Quantum Measurements

Performing a quantum measurement yields two different results: a classical measurement outcome and a quantum output corresponding to the post-measurement state. Quantum devices that provide both outcomes can be described through quantum instruments. In a realistic scenario, one can expect that the observer's obtained classical and quantum outcomes are non-ideal: this can be due to experimental limitations, but could also be explained by adversarial interference, that is, a second party that disturbs the device through a concealed measurement to obtain information. The second scenario can be interpreted through quantum compatibility, as it implies that both the observer's instrument and the adversary's measurement can be performed simultaneously. In this talk I discuss how the noise of the observer's device relates to the amount of information that the adversary can obtain.
