Entanglement Sampling and Applications

Popis výsledku v původním jazyce

A natural measure for the amount of quantum information that a physical system E holds about another system A = A(1), ... , A(n) is given by the min-entropy H-min(A vertical bar E). In particular, the min-entropy measures the amount of entanglement between E and A, and is the relevant measure when analyzing a wide variety of problems ranging from randomness extraction in quantum cryptography, decoupling used in channel coding, to physical processes such as thermalization or the thermodynamic work cost (or gain) of erasing a quantum system. As such, it is a central question to determine the behavior of the min-entropy after some process M is applied to the system A. Here, we introduce a new generic tool relating the resulting min-entropy to the originalone, and apply it to several settings of interest. A simple example of such a process is the one of sampling, where a subset S of the systems A(1), ... , A(n) is selected at random.
