Role of energy-invariant assistants in energy extraction from quantum batteries
Paranjoy Chaki, Aparajita Bhattacharyya, Kornikar Sen +1
We investigate the role of energy-invariant assistants in energy extraction from quantum batteries. To this end, for energy extraction, we restrict ourselves to unitaries that join…
Designing a Universal Quantum Switch for Arbitrary Quantum Dynamics
Priya Ghosh, Kornikar Sen, Ujjwal Sen
A quantum switch is a superoperator that, in general, creates a superposition of various causal orders of two or more quantum dynamics that are all divisible in the complete positi…
Positive and non-positive measurements in energy distillation from quantum batteries
Paranjoy Chaki, Aparajita Bhattacharyya, Kornikar Sen +1
We investigate energy distillation from quantum batteries within the framework of generalized quantum measurements, including both positive operator-valued measurements (POVMs) and…
Minimal-error quantum state discrimination versus robustness of entanglement:More indistinguishability with less entanglement
Debarupa Saha, Kornikar Sen, Chirag Srivastava +1
We relate the the distinguishability of quantum states with their robustness of the entanglement, where the robustness of any resource quantifies how tolerant it is to noise. In pa…
