Optical Quantum Computation
This program investigates fundamental and applied theoretical questions surrounding quantum communication and computation technologies. Quantum Communication Theory focuses particularly on quantum communication protocols in which the information is encoded on the optical field variables – so-called continuous variable (CV) protocols, and seeks tighter security proofs and to develop quantum repeater technologies. Optical Quantum Computation Theory focuses on the design and optimisation of quantum circuits for medium-scale (5 – 50 qubit) demonstrations and applications. We collaborate closely with the experimental programs in designing and analysing experimental demonstrations and prototypes.
Quantum technologies offer the potential for breakthroughs in fields of computation, encryption, communications and metrology. A major barrier, however, to the broad adoption of this technology is the inability to efficiently store, interfere and detect quantum states. This program will develop innovative gas-phase photonic technologies to enable manipulation of photons at the quantum level. This has the potential to improve the efficiency, speed and scalability of quantum computing and communication devices.
The Optical Quantum Information Program is investigating the use of quantum states of light, primarily single and entangled photons, to realize key advances in quantum computing and communications protocols. As well as developing the novel use of entanglement, encodings and sophisticated optical circuits for advancing the practicality of quantum computing, the program will contribute heralded amplifier technology and memory-compatible entanglement towards the Centre's larger goal of building quantum repeater technology.
The goal of the Hybrid Photonic Qubits program is to conduct experiments in optical quantum computing leading to the demonstration efficient teleportation-based quantum gates, and to contribute to the Centre’s research in Quantum Communications and Quantum Resources through the development of high-speed quantum measurement and control systems.
