Diverse tunable dynamics of two quantum random walkers
Shrabanti Dhar, Abdul Khaleque, Tushar Kanti Bose
Quantum walk research has mainly focused on evolutions due to repeated applications of time-independent unitary coin operators. However, the idea of controlling the single particle…

Measurement-Induced Phase Transition in a Quantum Spin System
Shrabanti Dhar, Subinay Dasgupta
Suppose a quantum system starts to evolve under a Hamiltonian from some initial state. When for the first time, will an observable attain a preassigned value? To answer this questi…
