Surpassing thermal-state limit in thermometry via non-completely positive quantum encoding
Anindita Sarkar, Paranjoy Chaki, Debarupa Saha +1
Conventional quantum thermometry assumes completely positive (CP) encoding maps, where the probe is initially uncorrelated with the environment. We consider realistic scenarios wit…

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,…
