Vanishing quantum discord is not necessary for completely-positive maps
Aharon Brodutch, Animesh Datta, Kavan Modi +2
The description of the dynamics of a system that may be correlated with its environment is only meaningful within the context of a specific framework. Different frameworks rely upo…
Unification of witnessing initial system-environment correlations and witnessing non-Markovianity
César A. Rodríguez-Rosario, Kavan Modi, Laura Mazzola +1
We show the connection between a witness that detects dynamical maps with initial system-environment correlations and a witness that detects non-Markovian open quantum systems. Our…
Positivity in the presence of initial system-environment correlation
Kavan Modi, César A. Rodríguez-Rosario, Alán Aspuru-Guzik
The constraints imposed by the initial system-environment correlation can lead to nonpositive Dynamical maps. We find the conditions for positivity and complete positivity of such…
Dynamical role of system-environment correlations in non-Markovian dynamics
Laura Mazzola, Cesar A. Rodrıguez-Rosario, Kavan Modi +1
We analyse the role played by system-environment correlations in the emergence of non-Markovian dynamics. By working within the framework developed in Breuer et al., Phys. Rev. Let…
Synthesis of Reversible Functions Beyond Gate Count and Quantum Cost
Robert Wille, Mehdi Saeedi, Rolf Drechsler
Many synthesis approaches for reversible and quantum logic have been proposed so far. However, most of them generate circuits with respect to simple metrics, i.e. gate count or qua…
Brief review related to the foundations of time-dependent density functional theory
Thomas A. Niehaus, Norman H. March
The electron density $n(\rb,t)$, which is the central tool of time-dependent density functional theory, is presently considered to be derivable from a one-body time-dependent poten…
