Quantum state transfer and periodicity in discrete-time quantum walks under non--Markovian dephasing noise

Monika Rani, Supriyo Dutta, Subhashish Banerjee

In quantum communication, quantum state transfer from one location to another in a quantum network plays a prominent role, where the impact of noise could be crucial. The idea of s…

Non-Markovianity in Discrete-Time Open Quantum Random Walk on Arbitrary Graphs

Monika Rani, Supriyo Dutta, Subhashish Banerjee

In this work, we present a new model of the Discrete-Time Open Quantum Walk (DTOQW) applicable to an arbitrary graph, thereby going beyond the case of quantum walks on regular grap…

Qudit States in Noisy Quantum Channels

Supriyo Dutta, Subhashish Banerjee, Monika Rani

In this work, we analyze a number of noisy quantum channels on a family of qudit states. The channels studied are the dit-flip noise, phase flip noise, dit-phase flip noise, depola…

Space-time fluctuations and a stochastic Schrödinger-Newton equation

Sayantani Bera, Priyanka Giri, Tejinder P. Singh

We propose a stochastic modification of the Schrödinger-Newton equation which takes into account the effect of extrinsic spacetime fluctuations. We use this equation to demonstrate…
