Mission Statement

The International Society for Relativistic Quantum Information has been established to promote international cooperation and understanding for research and education in relativistic quantum information science.


What is Relativistic Quantum Information?

Quantum theory and general relativity are famously at loggerheads. Their mathematical languages are different and conceptual bases are discordant, if not outright conflicting. For more than sixty years this conceptual gap and scant experimental evidence has been preventing unification of the two theories.

At the close of the last century a seemingly unrelated development of quantum information theory helped to unriddle some of the long-standing conceptual problems in quantum mechanics. While originally discussed in terms of non-relativistic quantum mechanics, recent years have seen increasing research interest and activities in placing quantum information in a more rigorous framework of quantum field theory in curved spacetimes. As a matter of fact, information theory is often appealed to in black hole physics and gravitational theories, particularly in relation to the information loss paradox and the holographic principle.

A relationship of "R" and "QI" is twofold. On the one hand, quantum field theory is an instrumental tool in proposed designs of quantum computing and communication, and to comprehend the meaning and possibilities of quantum non-locality, and entanglement in the quantum vacuum. On the other hand, what ''R'' entails in RQI is perhaps best captured by what a relativist does traditionally: encompassing special and general relativity, geometry and topology (of spacetime and gauge fields), quantum field theory in curved spacetime and quantum gravity.

We see that this emergent interdisciplinary field has great potential for future development and impact on theoretical physics. At the same time, it also provides a completely new framework for experiments that could not be conceived before, neither in gravitational theory nor quantum information science.
