Quantum Semi-Markov Processes [PDF]
Physical Review Letters, 2008 We construct a large class of non-Markovian master equations that describe the dynamics of open quantum systems featuring strong memory effects, which relies on a quantum generalization of the concept of classical semi-Markov processes. General conditions for the complete positivity of the corresponding quantum dynamical maps are formulated.

Controlled information transfer in continuous-time chiral quantum walks
New Journal of Physics, 2021 In this paper we investigate properties of continuous time chiral quantum walks, which possess complex valued edge weights in the underlying graph structure, together with an initial Gaussian wavefunction spread over a number of vertices.

Quantum teleportation with atoms: quantum process tomography [PDF]
, 2007 The performance of a quantum teleportation algorithm implemented on an ion trap quantum computer is investigated. First the algorithm is analyzed in terms of the teleportation fidelity of six input states evenly distributed over the Bloch sphere ...

Quantum thermodynamics of general quantum processes [PDF]
Physical Review E, 2015 Accurately describing work extraction from a quantum system is a central objective for the extension of thermodynamics to individual quantum systems. The concepts of work and heat are surprisingly subtle when generalizations are made to arbitrary quantum states.

Asymmetric Quantum Steering Generated by Triple-Photon Down-Conversion Process With Injected Signals
Frontiers in Physics, 2022 Asymmetric quantum steering generated by the triple-photon down-conversion process in an injected signal optical cavity is investigated. The triple-photon down-conversion process can be realized in an optical superlattice by quasi-phase-matching ...

Quantum gate characterization in an extended Hilbert space [PDF]
, 2004 We describe an approach for characterizing the process of quantum gates using quantum process tomography, by first modeling them in an extended Hilbert space, which includes non-qubit degrees of freedom.

Quantum Dynamics and Information, 2010 A number of ideas and questions related to the construction of quantum processes are discussed. Quantum state extension, entanglement and asymptotic behaviour of the entropy are some of the issues explored. These topics are studied in more detail for a class of quantum processes known as finitely correlated states.

Tomography of a multimode quantum black box
New Journal of Physics, 2015 We report a technique for experimental characterization of an M -mode quantum optical process, generalizing the single-mode coherent-state quantum-process tomography method [ 1 , 2 ].
