Quantum random walk is the quantum counterpart of a classical random walk. The classical
random walk concept has long been used as a computational framework for designing …

Vector vortex beams (VVBs) have attracted significant attention in both classical and
quantum optics. Liquid crystal (LC), beyond its applications in information display, has …

Several quantum protocols, with applications ranging from fundamental studies to
cryptographic scenarios, can be enhanced through the generation and manipulation of …

We study maximal coin-position entanglement generation via a discrete-time quantum walk,
in which the coin operation is randomly selected from one of two coin operators set at each …

Entanglement with single-particle states is advantageous in quantum technology because of
the states' ability to encode and process information more securely than their multiparticle …

Recently, a generalization of a nonstandard step operator named the elephant quantum
walk (EQW) was introduced. With proper statistical distribution for the steps, that generalized …

Maximally entangled single-particle states (MESPS) are opening new possibilities in
quantum technology, as they have the potential to encode more information and are robust …

Quantum walk (QW) is the quantum analog of the random walk. QW is an integral part of the
development of numerous quantum algorithms. Hence, an in-depth understanding of QW …

We study a 2D disordered discrete-time quantum walk (QW) based on 1D generalized
elephant QW where an entangling coin operator is assumed. We show that considering a …

We report that the position-inhomogeneous quantum walk (IQW) can be utilized to produce
the maximal high-dimensional entanglement while maintaining the quadratic speedup …
