Optimal work extraction in measurement-based quantum Otto engines: Non-adiabaticity and generalized measurements can be beneficial
Arunabha Das, Sayan Mondal, Debarupa Saha +1
Measurement-based quantum heat engines have attracted significant interest as alternatives to conventional thermal engines, as they replace the hot thermal reservoir with quantum m…

Role reversal in quantum Mpemba effect
Arunabha Das, Paranjoy Chaki, Priya Ghosh +1
We investigate the quantum Mpemba effect in a dissipative Dicke model, which consists of a spin-1/2 ensemble coupled to a bosonic mode, which in turn is coupled to a bosonic bath.…

Measurement-device-independent Schmidt number certification of all entangled states
Saheli Mukherjee, Bivas Mallick, Arun Kumar Das +2
Bipartite quantum states with higher Schmidt numbers have been shown to outperform those with lower Schmidt numbers in various quantum information processing tasks, highlighting th…
