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.

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. The project will discover physics of complex dynamics and investigate unexplored physical phenomena in the laboratory, like an antenna of photosynthetic systems that use complex surroundings for efficient and fast energy transport. The project is expected to help build new and improved quantum machines.Read moreRead less

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. 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

Principles and applications of quantum causal discovery. 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.

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. The project will create filtering protocols, suppressing characterised noise via appropriate controls. This is expected to lead to greater control over systems, demanded by quantum computers and nano devices, like next generation computer chips.
