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 ...

Resonant tunneling in disordered borophene nanoribbons with line defects
npj Computational Materials, 2022 Recently, borophene has attracted extensive interest as the wonder material, showing that line defects (LDs) occur widely at the interface between $$\nu _{1/5}$$ ν 1 / 5 and $$\nu _{1/6}$$ ν 1 / 6 boron sheets.

Witnessing quantum memory in non-Markovian processes [PDF]
Quantum, 2021 We present a method to detect quantum memory in a non-Markovian process. We call a process Markovian when the environment does not provide a memory that retains correlations across different system-environment interactions.

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.

Application of Quantum Process Calculus to Higher Dimensional Quantum Protocols [PDF]
Electronic Proceedings in Theoretical Computer Science, 2014 We describe the use of quantum process calculus to describe and analyze quantum communication protocols, following the successful field of formal methods from classical computer science.

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 ].

Choi's Proof and Quantum Process Tomography [PDF]
, 2002 Quantum process tomography is a procedure by which an unknown quantum operation can be fully experimentally characterized. We reinterpret Choi's proof of the fact that any completely positive linear map has a Kraus representation [Lin. Alg. and App., 10,
