Complexity for one-dimensional discrete time quantum walk circuits
Aranya Bhattacharya, Himanshu Sahu, Ahmadullah Zahed +1
We compute the complexity for the mixed state density operator derived from a one-dimensional discrete-time quantum walk (DTQW). The complexity is computed using a two-qubit quantu…

A simple coin for a entangled walk
Ahmadullah Zahed, Kallol Sen
We analyze the effect of a simple coin operator, built out of Bell pairs, in a Discrete Quantum Random Walk (DQRW) problem. The specific form of the coin enables us to find an…
