Harnessing energy extracted from heat engines to charge quantum batteries
Debarupa Saha, Aparajita Bhattacharyya, Kornikar Sen +1
We explore the performance of three- and two-stroke heat engines with a qutrit working substance in charging two-level quantum batteries. We first classify the heat engines into tw…
Temperature- and interaction-tweaked efficiency boost of finite-time robust quantum Otto engines
Debarupa Saha, Ahana Ghoshal, Ujjwal Sen
We demonstrate that under specific conditions, a finite-time quantum Otto engine, employing a spin-1/2 particle as the working substance, despite undergoing incomplete Otto cycles,…
Entanglement is indispensable for masking arbitrary set of quantum states
Debarupa Saha, Priya Ghosh, Ujjwal Sen
We question the role of entanglement in masking quantum information contained in a set of mixed quantum states. We first show that a masker that can mask any two single-qubit pure…
