Hyper-entanglement between pulse modes and frequency bins
Fabrizio Chiriano, Joseph Ho, Christopher L. Morrison +4
Hyper-entanglement between two or more photonic degrees of freedom (DOF) can enhance and enable new quantum protocols by allowing each DOF to perform the task it is optimally suite…
Conference key agreement in a quantum network
Alexander Pickston, Joseph Ho, Andrés Ulibarrena +6
Quantum conference key agreement (QCKA) allows multiple users to establish a secure key from a shared multi-partite entangled state. In a quantum network, this protocol can be effi…
Experimental demonstration of optimal unambiguous two-out-of-four quantum state elimination
Jonathan W. Webb, Ittoop V. Puthoor, Joseph Ho +4
A core principle of quantum theory is that non-orthogonal quantum states cannot be perfectly distinguished with single-shot measurements. However, it is possible to exclude a subse…
Frequency-bin entanglement from domain-engineered down-conversion
Christopher L. Morrison, Francesco Graffitti, Peter Barrow +3
Frequency encoding is quickly becoming an attractive prospect for quantum information protocols owing to larger Hilbert spaces and increased resilience to noise compared to other p…
Quantum communication complexity beyond Bell nonlocality
Joseph Ho, George Moreno, Samuraí Brito +8
Efficient distributed computing offers a scalable strategy for solving resource-demanding tasks such as parallel computation and circuit optimisation. Crucially, the communication…
Optimised Domain-engineered Crystals for Pure Telecom Photon Sources
Alexander Pickston, Francesco Graffitti, Peter Barrow +4
The ideal photon-pair source for building up multi-qubit states needs to produce indistinguishable photons with high efficiency. Indistinguishability is crucial for minimising erro…
