Resources for Quantum Networks. In classical information theory communication is an important resource. In quantum information theory there are the additional resources of entanglement and quantum communication. The aim of this project is to establish a complete theory of resources for quantum networks, by determining the relation between these resources, their symmetry properties, and effective ways of calculating capacities.

In quantum information theory there are the additional resources of entanglement and quantum communication. The aim of this project is to establish a complete theory of resources for quantum networks, by determining the relation between these resources, their symmetry properties, and effective ways of calculating capacities. Critical issues, such as the networking of quantum computers, quantum teleportation and secure communication, require a complete theory of resources. The expected outcome of this project is a rigorous foundation for resources in quantum information that may be used to address these issues.Read moreRead less
Quantum equilibration. This project will shed light on a fundamental problem in physics - how do fragile quantum systems, entirely isolated from the rest of the world, return to equilibrium when disturbed from their natural state? Our results will provide a theoretical underpinning for the development of quantum simulators that can be used for the design of advanced materials.

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

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. However, little is known about inferring causal relations between quantum events, a core problem in all scientific disciplines.

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

Optical realisations of continuous-variable quantum information. The project aims to develop a framework for optical realisations of continuous-variable quantum information. Such realisations offer the potential for major technological advances in quantum information processing in the near future, but are currently impeded by the lack of a well-defined theoretical foundation. This project aims to construct such a foundation, including energy cutoffs, detector resolution, and finite resources. ....Optical realisations of continuous-variable quantum information.

This project aims to construct such a foundation, including energy cutoffs, detector resolution, and finite resources. Feasible experiments to test and exploit continuous-variable quantum information processing will be proposed. The resulting framework will allow the field to progress beyond proof-of-principle demonstrations and to develop new, technology-driven quantum information protocols.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

Understanding the laws of physics by which complex interactions in many-particle systems lead to the emergence of new behaviour is a fundamental problem. The project seeks to understand the microscopic mechanisms and phenomenology of emergent transport phenomena in the motion of particles in quantum many-body systems. This project will develop new theories of quantum transport in ultracold atomic gases, which provide a unique avenue for addressing our aims by controlled realisation of novel and well-characterised microscopic models of many-body theory. This project will provide new insights into the structure-dynamics-functionality paradigm, enabling breakthrough applications in the bottom-up design of new materials and in cellular regulation in biology.Read moreRead less
