Emergence of superradiance in dissipative dipolar-coupled spin systems
Saptarshi Saha, Yeshma Ibrahim, Rangeet Bhattacharyya
In the superradiance phenomenon, a collection of non-interacting atoms exhibits collective dissipation due to interaction with a common radiation field, resulting in a non-monotoni…
Prethermalization in an open quantum system coupled to a spatially correlated Bosonic bath
Saptarshi Saha, Rangeet Bhattacharyya
A nearly-integrable isolated quantum many-body system reaches a quasi-stationary prethermal state before a late thermalization. Here, we revisit a particular example in the setting…
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…
Effects of dipolar coupling on an entanglement storage device
Saptarshi Saha, Rangeet Bhattacharyya
Quantum computation requires efficient long-term storage devices to preserve quantum states. An attractive candidate for such storage devices is qubits connected to a common dissip…
