Operational No-Signalling Constraints in Relativistic Spacetimes
Analysis
This paper investigates quantum correlations in relativistic spacetimes, focusing on the implications of relativistic causality for information processing. It establishes a unified framework using operational no-signalling constraints to study both nonlocal and temporal correlations. The paper's significance lies in its examination of potential paradoxes and violations of fundamental principles like Poincaré symmetry, and its exploration of jamming nonlocal correlations, particularly in the context of black holes. It challenges and refutes claims made in prior research.
Key Takeaways
- •Establishes a framework for studying quantum correlations in relativistic spacetimes.
- •Addresses potential paradoxes and violations of fundamental principles.
- •Explores the jamming of nonlocal correlations, including in black hole spacetimes.
- •Challenges and refutes claims from prior research.
“The paper shows that violating operational no-signalling constraints in Minkowski spacetime implies either a logical paradox or an operational infringement of Poincaré symmetry.”
