Sample Complexity of Black Box Work Extraction
Shantanav Chakraborty, Siddhartha Das, Arnab Ghorui +2
Extracting work from a physical system is one of the cornerstones of quantum thermodynamics. The extractable work, as quantified by ergotropy, necessitates a complete description o…

Conditional entropy and information of quantum processes
Siddhartha Das, Kaumudibikash Goswami, Vivek Pandey
What would be a reasonable definition of the conditional entropy of bipartite quantum processes, and what novel insight would it provide? We develop this notion using four informat…

Causal and Non-Causal Revivals of Information: A New Regime of Non-Markovianity in Quantum Stochastic Processes
Francesco Buscemi, Rajeev Gangwar, Kaumudibikash Goswami +5
The study of information revivals, witnessing the violation of certain data-processing inequalities, has provided an important paradigm in the study of non-Markovian quantum stocha…
