Using Interactive Digital Storytelling to Represent Transformative Quantum Technologies in Augmented/Extended Reality Environments

Summary A major roadblock to the broader adoption of quantum technologies is the long learning curve associated with their seemingly abstract concepts. This often renders quantum technologies inaccessible to most audiences, especially through explanations using conventional scientific language. In this project, we develop novel methods of interactive digital storytelling – augmented and extended reality (AR/XR) […]

A Reformulation of Quantum Game Theory

Summary Classical game theory – conducted at the interface between economics and computer science – has found applications in topics ranging from networking and security to online markets. Despite over 20 years of research into connections between game theory and quantum information, we have yet to see any significant implications of quantum information when applied […]

Towards large area, resonant quantum tunneling diodes by continuous Langmuir transfer of exfoliated 2D materials

Summary  Atomically thin 2D materials constitute promising building blocks for quantum devices due to their exotic, layer-dependent electronic properties. The ability to stack these materials in alternating layers enables heterostructures to be built in almost limitless combinations and over small enough length scales to observe quantum phenomena. So far though, practical implementation of devices based […]

Entangled Photon Orbital Angular Momentum Arrays

Summary Arrays of orbital angular momentum (OAM) states of light are a new form of structured light so far relatively unexplored in quantum information science. Unlike spin angular momentum of light, which is related to light’s polarization and covers two dimensions, OAM states, sometimes described as ‘donut beams’ due to the shape of the field […]

Novel High-Speed Receiver for Quantum Communication and Sensing

Summary  An essential aspect of a quantum channel is the detection and analysis of quantum signals in the form of photons. For most free-space applications, the photons are polarization encoded, e.g. by assigning the ‘0’ to horizontally polarized photons and ‘1’ to vertically polarized photons. However, where the geometric reference is not constant at all […]

Quantum Sensing Applications using Quantum Communication Technology

Summary   The Quantum Encryption and Science Satellite provides a platform to develop and deploy quantum sensing and metrology via photonic channels. This project will build upon ‘free-space’ quantum communication technology and explore new approaches and methods to advance two primary applications: quantum-enhanced telescopes, and spectroscopic sensing for methane detection in the atmosphere. For the […]

Hybrid Quantum Repeater based on Atomic Quantum Memories and Telecom Wavelength Entangled Photon-Pairs Generated from Semiconductor Nanowires

Summary   Losses in physical channels, such as optical fibres, limit existing quantum communication systems to modest distance ranges. Since amplification of quantum signals is fundamentally not possible,  we look to extend the range and functionality of these quantum channels by adding quantum memory nodes that can daisy-chain multiple lengths of quantum channels through entanglement […]

On-Chip Microwave-Optical Quantum Interface

Summary   In this project we develop a quantum interface between microwave and optical photons as a key enabling technology of a hybrid quantum network. In such a network, the robust optical photons carry quantum information through optical fibres over long distances, while superconducting microwave circuits protected from thermal photon noise by the low temperature […]

Distributing Multimode Entanglement with Microwave Photons

Microwaves have enabled numerous classical technologies, in part because they propagate through air with little energy loss.
