Bounds on the dynamics of periodic quantum walks and emergence of the gapless and gapped Dirac equation
N. Pradeep Kumar, Radhakrishna Balu, Raymond Laflamme +1
We study the dynamics of discrete-time quantum walk using quantum coin operations, and in time-dependent periodic sequence. For the two-period quantum…
Non-Markovian evolution: a quantum walk perspective
Pradeep Kumar, Subhashish Banerjee, R. Srikanth +2
Quantum non-Markovianity of a quantum noisy channel manifests typically as information backflow, characterized by the departure of the intermediate map from complete positivity, th…
Non-Markovian Dynamics of Discrete-Time Quantum Walks
Subhashish Banerjee, N. Pradeep Kumar, R. Srikanth +2
In the case of the discrete time coined quantum walk the reduced dynamics of the coin shows non-Markovian recurrence features due to information back-flow from the position degree…
