Emergence and stability of discrete time-crystalline phases in open quantum systems
Saptarshi Saha, Rangeet Bhattacharyya
Here we provide a theoretical framework to analyze discrete time-crystalline phases (DTC) in open quantum many-body systems. As a particular realization, we choose a quantum many-b…
Optimal fidelity in implementing Grover's search algorithm on open quantum system
Nilanjana Chanda, Rangeet Bhattacharyya
We investigate the fidelity of Grover's search algorithm by implementing it on an open quantum system. In particular, we study with what accuracy one can estimate that the algorith…
Optimal population transfer using the adiabatic rapid passage in the presence of drive-induced dissipation
Nilanjana Chanda, Pratik Patnaik, Rangeet Bhattacharyya
Adiabatic rapid passage (ARP) is extensively used to achieve efficient transfer or inversion of populations in quantum systems. Landau and Zener accurately estimated the transfer p…
