Summary
Developing the next generation of single and entangled photon sources. Low noise and efficient sources of single and entangled photons are important resources to implement a scalable platform for large-scale quantum information tasks. This project will develop the prototypes for these sources which will be suitable for a wide range of interesting applications in quantum information.
Quantum networks based on superconducting circuits and dissipative channels. Superconducting circuits have great potential for probing and using quantum nature on a chip but lack networking capabilities between remote sites. However, non-local quantum correlations are critical for quantum devices to surpass classical systems.

Superconducting circuits have great potential for probing and using quantum nature on a chip but lack networking capabilities between remote sites. However, non-local quantum correlations are critical for quantum devices to surpass classical systems. This project aims to create capabilities for establishing entanglement between remote superconducting chips using non-local dissipative interaction. Within this approach the created entanglement can be also preserved as long as necessary as a resource for quantum protocols. The resulting technology is expected to enable quantum information processing in superconducting circuits on fundamentally larger scales and provides a powerful platform to test the limits for building artificial quantum systems.Read moreRead less

This project aims to develop advanced technologies to optically levitate macroscopic (millimetre-sized) objects and nanoscopic (atomically thin) materials. Levitation platforms built by the investigatory team are based on the resonantly amplified radiation pressure of laser beams. This new type of optical levitation can provide ultimate isolation of the systems from external noise, making them extremely responsive to subtle environmental changes. These platforms could be turned into sharp instruments for measuring metrological variables of interest and probing new physics. Quantum optical techniques could be developed to optimise the sensitivity of levitated systems to levels that allow the exploration of quantum and gravitational physics.Read moreRead less

This project will create the experimental tools to fully control the motion of a mechanical oscillator at the single-quanta level, opening a rich avenue for fundamental research and the development of quantum physics enhanced applications. This project will prepare a quantum state of a macroscopic mechanical resonator exhibiting quantum interference fringes at at an unprecedented mass scale. The observation of these fringes will enable the study of the intricacies of quantum decoherence and ultimately even probe quantum gravitational phenomena. To achieve these goals it will employ micro-scale optical resonators fabricated by established techniques, that also provide the ideal platform for scalable mechanical-oscillator-based quantum information applications.Read moreRead less

Precision laser levitation for quantum metrology and gravitational sensing: This fellowship project aims to levitate macroscopic objects using only laser beams, to provide a new tool to test physics theories. Strong laser beams can exert sufficient force to counteract gravity and make an object levitate. In contrast to other forms of levitation, laser levitation is scatter-free and can preserve system coherence. It has superior optical and mechanical quality factors and complete information of the system dynamics is retained. This allows laser levitation to be turned into a highly controllable and ultra-sensitive device capable of detecting minute environmental changes. This research aims to probe the relationship between quantum and gravitational physics and develop laser levitation into a precision instrument for the sensing of gravity. Laser levitation has the potential to be developed into technology for mineral exploration and environmental sensing.Read moreRead less

This project aims to use radiation pressure to levitate a small mirror. Using a tripod of laser beams, it is possible to levitate and trap the mirror in a stable position. Radiation pressure has been used before to levitate, but previous work has always involved scattering light from the levitating object. This project proposes the use of a high quality mirror, allowing the collection of the reflected light and the accurate measurement and control of the position of the mirror as it floats on the laser beams. Using the unique properties of the floating mirror, it will be possible to search for signatures of quantum gravity and develop tools for ultra-precision metrology.Read moreRead less

This project aims to sort fluorescent nanodiamonds according to their brightness using atomic radiation pressure. Fluorescent nanodiamonds can overcome all limitations associated with conventional fluorescent bio-labels. While readily available, their brightness varies greatly, so a method for yielding high-quality material with consistent brightness is needed. This project combines techniques from laser manipulation of cold atoms and microfluidics to create an optofluidic method of particle separation. The proposed device could sort nanodiamonds more than a billion times faster than active sorting techniques. This is expected to lead to better tools for bio-imaging and bio-manipulation.Read moreRead less
