Research

Our group is involved in several multidisciplinary research projects such as the design and fabrication of integrated quantum optical devices, quantum random number generation and ion trap quantum computing. As part of the ARC Centre of Excellence for Quantum Computation and Communication Technology we collaborate with some of the best groups in Australia and worldwide to enable quantum technologies for real world applications.

Single Photon Demultiplexing

or optics to remain a competitive technology in the race for new quantum communication and computation systems, new sources of single photons are required. To scale fundamental demonstrations to practical technology the available number of indistinguishable photons must be increased. Traditionally single photons have been generated by spontaneous parametric down conversion, a process that has

A fast, classical technique for measuring the 2-photon wavefunction from nonlinear photonic devices

The future of quantum photonics will see an increase in complexity of photonic devices and the quantum states they produce.  As the technology becomes more mainstream, techniques for large-scale photonics manufacturing will need to be developed.  A large hurdle in making this transition lies in testing and verifying the operation of these devices.  The technique

Ion-Photon Interface for Scalable Quantum Networking

Research into quantum networking has received widespread interest for its promise of guaranteed communication security and interfacing with quantum computers [1]. Information is encoded into quantum systems as quantum bits or qubits. Quantum communications over long distances requires qubits, encoded into photons, to remain coherent. With photon loss this distance is limited to less than

Multiplexed Quantum Random Number Generation via Vacuum Fluctuations

Random number generators are incorporated in applications ranging from cryptography to computer simulation and lottery systems. Modern random number generators typically utilise complex computer algorithms to hash an initial pseudo-random value. As one might guess, if the initial seed value is known, the random string of bits produced may be compromised. For applications such as cryptography,

Trapping Thorium for a Nuclear Atomic Clock

Ablation via a laser creates a plasma plume containing ions that can be loaded into an ion trap. The plasma plume is seen as the bright blue fluorescence. The quadrupole ion trap composed of 4 metal rods is housed in a vacuum chamber. Einstein showed time is not the constant thing we once thought it
