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…
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…
Repeater-Based Quantum Communication Protocol: Maximizing Teleportation Fidelity with Minimal Entanglement
Arkaprabha Ghosal, Jatin Ghai, Tanmay Saha +2
Transmitting unknown quantum states to distant locations is crucial for distributed quantum information protocols. The seminal quantum teleportation scheme achieves this feat while…
