Persistence of topological phases in non-Hermitian quantum walks [PDF]
Scientific Reports, 2021 Discrete-time quantum walks are known to exhibit exotic topological states and phases. Physical realization of quantum walks in a lossy environment may destroy these phases.

Dissipative Realization of a Quantum Distance-Based Classifier Using Open Quantum Walks [PDF]
EntropyOpen quantum walks (OQWs) constitute a class of quantum walks whose dynamics are entirely driven by interactions with the environment. It is well known that OQWs provide a general framework for implementing dissipative quantum computation.

Eigenvalues of Two-State Quantum Walks Induced by the Hadamard Walk [PDF]
Entropy, 2020 Existence of the eigenvalues of the discrete-time quantum walks is deeply related to localization of the walks. We revealed, for the first time, the distributions of the eigenvalues given by the splitted generating function method (the SGF method) of the

Implementing Parrondo’s paradox with two-coin quantum walks [PDF]
Royal Society Open Science, 2018 Parrondo’s paradox is ubiquitous in games, ratchets and random walks. The apparent paradox, devised by J. M. R. Parrondo, that two losing games A and B can produce a winning outcome has been adapted in many physical and biological systems to explain ...

Quantum walks and Dirac cellular automata on a programmable trapped-ion quantum computer [PDF]
Nature Communications, 2020 Implementations of quantum walks on ion trap quantum computers have been so far limited to the analogue simulation approach. Here, the authors implement a quantum-circuit-based discrete quantum walk in one-dimensional position space, realizing a Dirac ...

The expressive power of quantum walks in terms of language acceptance [PDF]
Electronic Proceedings in Theoretical Computer Science, 2014 Discrete time quantum walks are known to be universal for quantum computation. This has been proven by showing that they can simulate a universal quantum gate set.
