Complete positivity and entangled degrees of freedom

Abstract

We study how some recently proposed noncontextuality tests based on quantum interferometry are affected if the test particles propagate as open systems in the presence of a Gaussian stochastic background. We show that physical consistency requires the resulting Markovian dissipative time evolution to be completely positive.

Complete positivity in quantum open system dynamics

Fabio Benatti

The statistical interpretation of quantum mechanics requires that, while evolving in time, states of quantum systems keep a positive spectrum of eigenvalues. That is, the time-evolution must be positivity preserving or, in short, positive. When dealing with dissipative quantum systems, positivity is no longer sufficient. The presence of entangled states makes it necessary that the time-evolution be completely positive. In this paper we discuss this latter notion in relation to simple positivity and quantum entanglement.

OPEN QUANTUM SYSTEMS AND COMPLETE POSITIVITY

Roberto Floreanini B

The dynamics of an open quantum system is usually assumed to be generated by time-evolution equations of Lindblad form. It follows that the time evolutors are completely positive. Far from being just a useful technicality, complete positivity is one of the many aspects of quantum entanglement and is necessary to avoid physical inconsistencies. This issue is addressed by examining the open dynamics of two level systems in situations typical of chemical physics and quantum optics.

Complete positivity and dissipative factorized dynamics: some comments

Fabio Benatti, Roberto Floreanini B, Marco Piani +1 more

After reviewing the main properties of time-evolutions of open quantum systems, some considerations about the positivity of factorized Markovian dynamics for bipartite systems are made. In particular, it is shown that the positivity of the whole time-evolution in general does not ask for the complete positivity of the single system time-evolutions, if they are allowed to differ. However, they must be completely positive if one is a small perturbation of the other, which is the typical situation for open systems in a heat bath.

Non-Markovian master equations from entanglement with stationary unobserved degrees of freedom

Adrián A Budini, Henning Schomerus

We deduce a class of non-Markovian completely positive master equations which describe a system in a composite bipartite environment, consisting of a Markovian reservoir and additional stationary unobserved degrees of freedom that modulate the dissipative coupling. The entanglement-induced memory effects can persist for arbitrary long times and affect the relaxation to equilibrium, as well as induce corrections to the quantum-regression theorem. By considering the extra degrees of freedom as a discrete manifold of energy levels, strong non-exponential behaviour can arise, such as for example power law and stretched exponential decays.
