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

Harnessing genuine quantum nonlocality. This project aims to develop the science and tools behind device-independent quantum security for information networks. These gold-standard protocols rely on genuine quantum nonlocality but, to date, the strict performance requirements have been unachievable for general practical cases.

This project aims to develop the science and tools behind device-independent quantum security for information networks. These gold-standard protocols rely on genuine quantum nonlocality but, to date, the strict performance requirements have been unachievable for general practical cases. Further, the theory of nonlocality in multiparty networks is almost completely undeveloped. The project’s anticipated outcomes are novel experiment and theory to bypass barriers and open up nonlocal network protocols. It is also expected to rigorously establish that a single-photon wavefunction after a beamsplitter is truly nonlocal. Likely future benefits include secure random numbers, secure distributed information technology and world-best photon sources.Read moreRead less

Quantum physics and complexity. How much information about a system’s present is needed to predict its future? This project aims to show that the answer fundamentally depends on how information is stored. Simulations of partially random processes are critical in real-world applications. Surprisingly, theory suggests that a simulation must store much more classical data (like bits) than is required to determine its output. This wastes precious resources. Via optical quantum information experiment ....Quantum physics and complexity. How much information about a system’s present is needed to predict its future? This project aims to show that the answer fundamentally depends on how information is stored. Simulations of partially random processes are critical in real-world applications. Surprisingly, theory suggests that a simulation must store much more classical data (like bits) than is required to determine its output. This wastes precious resources. Via optical quantum information experiments, the project aims to demonstrate and characterise how storing and handling data in quantum states massively reduces this complexity overhead. Another goal is to use novel quantum optics ideas to greatly reduce communication complexity in important remote processing tasks.Read moreRead less

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
