Quantum SWITCH-induced non-Markovianity is not entirely quantum
Rajeev Gangwar, Ananda G. Maity
Indefinite causal order extends quantum information processing beyond fixed causal structures, with the quantum SWITCH serving as its canonical realization. By coherently superposi…
Genuine and Non-Genuine Quantum Non-Markovianity: A Unified Information-Theoretic Review
Rajeev Gangwar, Ujjwal Sen
Understanding whether the features of open quantum dynamics are genuinely quantum remains a central challenge in quantum dynamics. Even though the non-Markovian behavior of quantum…
Coherent heat transfer leads to genuine quantum enhancement in the performances of continuous engines
Brij Mohan, Rajeev Gangwar, Tanmoy Pandit +3
Conventional continuous quantum heat engines with incoherent heat transfer perform poorly as they exploit two-body interactions between the system and hot or cold baths, thus havin…
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…
Squashed quantum non-Markovianity: a measure of genuine quantum non-Markovianity in states
Rajeev Gangwar, Tanmoy Pandit, Kaumudibikash Goswami +2
Quantum non-Markovianity in tripartite quantum states represents a correlation between systems and when conditioned on the system and is known to have both c…
