This project aims to implement a quantum computer memory module which can be integrated in a future hybrid quantum computer, where the advantages of different quantum platforms are combined. The memory module will be achieved by coupling a superconducting qubit to the surface vibrations of superfluid helium and exchanging quantum information between the qubit and helium. By simulating chemical reactions, the project expects to find cleaner alternatives of current industrial processes, reducing environmental impact. The outcomes should provide significant benefits for testing the validity of quantum mechanics, and by contributing to the realisation of a quantum computer, contribute to broad socio-economic benefits.Read moreRead less
Quantum measurement as a resource. Advanced quantum computers will use modular measurements significantly enhancing their capabilities. However, due to the noisy environment, the measurements may have nontrivial effects on the computation. Making best use of realistic (hence imperfect) measurements is a challenging problem that hinders the development of these technologies.

Complex quantum dynamics for technological applications. This project aims to characterise dynamics of a quantum system immersed in a complex surrounding, such as a quantum computer interacting with an environment that remembers the computer’s past. Since there are no known methods for battling the effects of the environment on the computer when they are intertwined, this project will develop tools to combat these adverse effects.

Heisenberg’s uncertainty principle, the limits to knowledge, and the foundations of quantum theory. This project will establish what the uncertainty principle can teach us about quantum foundations, and will address why quantum theory obeys such a principle and why Nature chose quantum theory amongst other possible theories.

This project will establish what the uncertainty principle can teach us about quantum foundations, and will address why quantum theory obeys such a principle and why Nature chose quantum theory amongst other possible theories. Specifically, this project will determine how the uncertainty principle restricts the information one can get on incompatible measurements, by deriving new complementarity relations. These will clarify what can or cannot be done in the context of quantum information. This project will determine how much of a theory can be reconstructed from such relations and what other fundamental axioms are required to fully derive quantum theory. This will shed light on the reasons why Nature prefers it to other theories.Read moreRead less

This project aims to develop a comprehensive framework to discover causal relations in quantum experiments. Quantum information can solve practical problems involving quantum systems, providing great insight in the foundations of physics and a promise of revolutionary technology. However, little is known about inferring causal relations between quantum events, a core problem in all scientific disciplines. This project aims to develop tools to efficiently solve this task, which is expected to open a new direction in quantum information and applied quantum technologies, and provide a deeper understanding of causality in the quantum world. Such advances in the theoretical background for developing quantum technologies could benefit the economy.Read moreRead less

The project intends to provide a solid base of quantum algorithms that would enable quantum computers to tackle currently insurmountable problems. Many of the highest-value applications in computing are based on solving problems in physics. Quantum computers take advantage of the power of quantum mechanics to outperform even the fastest conceivable supercomputers. This project plans to use new tools in quantum algorithms to provide much faster ways for quantum computers to simulate physics, including molecular modelling, field theories that explain elementary forces in the universe, and differential equations needed to model classical physics. The increases in computing speed have the potential to enable new technology in areas such as drug design and materials science, as well as providing testable predictions for new theories of physics.Read moreRead less

This project aims to provide new understanding of information and security in higher-dimensional systems, and to exploit this to deliver a secure, high-capacity, quantum image transfer protocol for quantum communication and quantum cryptography technologies. In quantum physics, the best possible knowledge of a whole does not include the best possible knowledge of the parts: not knowing any of the letters of a word does not imply not knowing what the word is. This project aims to examine the high-dimensional transverse spatial modes of photon to show that the converse is also true: not knowing the word does not imply not knowing any of the letters. Project outcomes may have applications in remote sensing and surveillance.Read moreRead less

Self-calibrating quantum devices. This project aims to improve control over quantum systems. It will develop self-calibrating quantum devices, the equivalent of Noise Cancelling Headphones for quantum systems.
