Enhanced non-Markovian behavior in quantum walks with Markovian disorder
N. Pradeep Kumar, Subhashish Banerjee, C. M. Chandrashekar
Non-Markovian quantum effects are typically observed in systems interacting with structured reservoirs. Discrete-time quantum walks are prime example of such systems in which, quan…
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 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…
