Randomness in (Quantum) Information Processing
... There are two basic approaches to deal with the aforementioned problems. The first one is to study possible usage of weak random sources in particular problems and applications. A bit surprisingly, for quite a few problems it is possible to design solutions that work sufficiently well even with weak ...

Distance between quantum states in the presence of initial qubit
... state, the reduced dynamics is completely positive and hence contractive with respect to some metrics. In consequence, the distance D[ρ1 ,ρ2 ] between two states can tend to zero when the system approaches a unique steady state (i.e., the dynamics is relaxing). We emphasize that contractivity is not ...
