Generic quantum walk using a coin-embedded shift operator
C. M. Chandrashekar
The study of quantum walk processes has been widely divided into two standard variants, the discrete-time quantum walk (DTQW) and the continuous-time quantum walk (CTQW). The conne…

Symmetry-noise interplay in quantum walk on an n-cycle
Subhashish Banerjee, R. Srikanth, C. M. Chandrashekar +1
Augmenting the unitary transformation which generates a quantum walk by a generalized phase gate G is a symmetry for both noisy and noiseless quantum walk on a line, in the sense t…

Quantum phase transition using quantum walks in an optical lattice
C. M. Chandrashekar, Raymond Laflamme
We present an approach using quantum walks (QWs) to redistribute ultracold atoms in an optical lattice. Different density profiles of atoms can be obtained by exploiting the contro…
