A quantum repeater is a device that can faithfully relay quantum information and extend quantum communication range. The Quantum Repeater Technology Program, led by Professor Ping Koy Lam based at The Australian National University, looks at realizing quantum amplification, quantum resources and quantum processes essential for an operational quantum repeater. By developing and integrating quantum components into a single platform to demonstrate the operation of a quantum repeater, the program aims to design precise and optimal architectures of a quantum repeater system.
