Relativistic Quantum Information Theory Based on Unequal-Time Quantum Field Theory Correlation Functions
This paper proposes a novel approach to relativistic quantum information theory by leveraging unequal-time correlation functions in quantum field theory to define and quantify quantum resources, moving beyond traditional entanglement-based methods.
Bipartite Relativistic Quantum Information: An Effective Field Theory Approach to Entanglement Harvesting, Quantum Discord, and Nonlocality
This paper explores how the principles of effective field theory (EFT) can be applied to understand relativistic quantum information (RQI), particularly focusing on entanglement harvesting, quantum discord, and nonlocality in a system of two Unruh-DeWitt (UDW) detectors interacting with a quantum field in the presence of a black hole.
Closed-Form Expressions for Smeared Bi-Distributions of a Massless Scalar Field in Minkowski Spacetime and their Applications to Relativistic Quantum Information Protocols
This paper derives novel closed-form expressions for smeared bi-distributions of a massless scalar field in Minkowski spacetime and utilizes these expressions to analyze relativistic quantum information protocols, particularly entanglement harvesting between two Unruh-DeWitt detectors.
