Efficient quantum walk on a quantum processor [PDF]
Nature Communications, 2016 Quantum walks are a potential framework for developing quantum algorithms, but have so far been limited to analogue quantum-simulation approaches that do not scale.

First Detection and Tunneling Time of a Quantum Walk [PDF]
Entropy, 2023 We consider the first detection problem for a one-dimensional quantum walk with repeated local measurements. Employing the stroboscopic projective measurement protocol and the renewal equation, we study the effect of tunneling on the detection time ...

A New Limit Theorem for Quantum Walk in Terms of Quantum Bernoulli Noises [PDF]
Entropy, 2020 In this paper, we consider limit probability distributions of the quantum walk recently introduced by Wang and Ye (C.S. Wang and X.J. Ye, Quantum walk in terms of quantum Bernoulli noises, Quantum Inf. Process. 15 (2016), no. 5, 1897–1908).

Quantum walk hydrodynamics. [PDF]
Sci Rep, 2019 AbstractA simple Discrete-Time Quantum Walk (DTQW) on the line is revisited and given an hydrodynamic interpretation through a novel relativistic generalization of the Madelung transform. Numerical results show that suitable initial conditions indeed produce hydrodynamical shocks and that the coherence achieved in current experiments is robust enough ...

Universal quantum computing using single-particle discrete-time quantum walk [PDF]
Scientific Reports, 2021 Quantum walk has been regarded as a primitive to universal quantum computation. In this paper, we demonstrate the realization of the universal set of quantum gates on two- and three-qubit systems by using the operations required to describe the single ...

A Quantum Walk Model for Idea Propagation in Social Network and Group Decision Making [PDF]
Entropy, 2021 We propose a quantum walk model to investigate the propagation of ideas in a network and the formation of agreement in group decision making. In more detail, we consider two different graphs describing the connections of agents in the network: the line ...
