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…
Local entanglement transfer to multiple pairs of spatially separated observers
Tanmoy Mondal, Kornikar Sen, Chirag Srivastava +1
Entanglement is an advantageous but at the same time a costly resource utilized in various quantum tasks. For an efficient usage and deployment of entanglement, we envisage the sce…
Auxiliary-assisted energy distillation from quantum batteries
Paranjoy Chaki, Aparajita Bhattacharyya, Kornikar Sen +1
We discuss the idea of extracting energy from a quantum battery, applying a projective measurement on an auxiliary system. The battery is initially connected to the auxiliary syste…
Noncompletely Positive Quantum Maps Enable Efficient Local Energy Extraction in Batteries
Aparajita Bhattacharyya, Kornikar Sen, Ujjwal Sen
Energy extraction from quantum batteries by means of completely positive trace-preserving (CPTP) maps leads to the concept of CPTP-local passive states, which identify bipartite st…
Effects of noise on performance of Bernstein-Vazirani algorithm
Archi Gupta, Priya Ghosh, Kornikar Sen +1
The Bernstein-Vazirani (BV) algorithm offers exceptional accuracy in finding the hidden bit string of a function. We explore how the algorithm performs in real-world situations whe…
Effects of the detection loophole on rival entanglement attestation techniques
Paranjoy Chaki, Kornikar Sen, Ujjwal Sen
Loopholes present in an experimental set-up can significantly affect the reliability of entanglement detection. We discuss two methods for detection of entanglement: one is by usin…
Noisy quantum batteries
Kornikar Sen, Ujjwal Sen
In realistic situations, physical systems can not be completely isolated from its environment. Its inevitable interaction with the environment can influence the working process of…
