Entanglement Degradation in the Presence of Markovian Noise: a Statistical Analysis

Abstract

Adopting a statistical approach we study the degradation of entanglement of a quantum system under the action of an ensemble of randomly distributed Markovian noise. This enables us to address scenarios where only limited information is available on the mechanisms that rule the noisy evolution of the model. As an application, we characterize the statistic of entanglement deterioration for a quantum memory formed by $n$ qudits that undergo randomly distributed local, uniform, Markovian noise evolution.
