US Army Research Laboratory, Center for Distributed Quantum Information (CDQI)
Light-matter Interfaces for Quantum Information Science
The U.S. Army Research Laboratory (ARL) Center for Distributed Quantum Information (CDQI) is a collaborative basic research effort connecting ARL, academic, industrial and other government researchers to develop a multi-site, multi-node, modular quantum network based on resilient distributed quantum entanglement preserved by quantum memory and quantum error correction. The Center will explore the fundamentals of a quantum network physical layer, with the long-term objective of identifying and providing beyond-classical capabilities for Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance for stationary and mobile Army elements. Distributed quantum systems may ultimately provide the enabling foundation for many capabilities and applications that are impossible or impractical to achieve through classical means, including quantum teleportation-based, tamper-evident, secure, long-haul communications; a network of high-precision globally-synchronized atomic clocks; and a network of quantum sensors with quantum-limited sensitivity.
