Discrete time quantum walk model for single and entangled particles to retain entanglement in coin space
C. M. Chandrashekar
In most widely discussed discrete time quantum walk model, after every unitary shift operator, the particle evolves into the superposition of position space and settles down in one…

Symmetries and noise in quantum walk
C. M. Chandrashekar, R. Srikanth, Subhashish Banerjee
We study some discrete symmetries of unbiased (Hadamard) and biased quantum walk on a line, which are shown to hold even when the quantum walker is subjected to environmental effec…

Implementing the one-dimensional quantum (Hadamard) walk using a Bose-Einstein Condensate
C. M. Chandrashekar
We propose a scheme to implement the simplest and best-studied version of quantum random walk, the discrete Hadamard walk, in one dimension using coherent macroscopic sample of ult…
