Instrument-based quantum resources: quantification, hierarchies and constructing resource theories
Jatin Ghai, Arindam Mitra
Quantum resources are certain features of the quantum world that provide advantages in certain information-theoretic, thermodynamic, or other useful operational tasks that are outs…
Genuine certification of incompatible quantum instruments through sequential communication tasks
Arindam Mitra, Satyaki Manna, Debashis Saha
Quantum instruments constitute the general description of quantum dynamics, encompassing both quantum measurements and quantum channels as special cases. Consequently, the incompat…
Informational completeness of qubit measurements and IC preservability of qubit channels: Characterization and Quantification
Jatin Ghai, Arindam Mitra
Informationally complete (IC) measurements are a useful class of measurements, as their outcome statistics uniquely determine an unknown quantum state. Hence, they are important fo…
Comparing quantum channels using Hermitian-preserving trace-preserving linear maps: A physically meaningful approach
Arindam Mitra, Jatin Ghai
In quantum technologies, quantum channels are essential elements for the transmission of quantum states. The action of a quantum channel usually introduces noise in the quantum sta…
Distance-based measures and Epsilon-measures for measurement-based quantum resources
Arindam Mitra, Sumit Mukherjee, Changhyoup Lee
Quantum resource theories provide a structured and elegant framework for quantifying quantum resources. While state-based resource theories have been extensively studied, their mea…
