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 ...

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 ...

Multi-bit quantum random number generation from a single qubit quantum walk [PDF]
Scientific Reports, 2019 We present a scheme for multi-bit quantum random number generation using a single qubit discrete-time quantum walk in one-dimensional space. Irrespective of the initial state of the qubit, quantum interference and entanglement of particle with the ...
