Single-Satellite Quantum Repeater Performance Analysis
Cameron Paterson, Jasminder S. Sidhu, Thomas Brougham +2
Space-based entanglement distribution has the potential to extend the range of quantum communication beyond that achievable through optical fibres that are constrained by exponenti…
Operational limits to entanglement-based satellite quantum key distribution
Jasminder S. Sidhu, Sarah E. McCarthy, Cameron Paterson +1
Space-based distribution of quantum entanglement will be essential for global quantum networking and secure communications. Modelling and analysis of the performance of satellite e…
Satellites promise global-scale quantum networks
Sumit Goswami, Sayandip Dhara, Neil Sinclair +10
Academia, governments, and industry around the world are on a quest to build long-distance quantum communication networks for a future quantum internet. Using air and fiber channel…
Attainability of quantum state discrimination bounds with collective measurements on finite copies
Lorcan Conlon, Jin Ming Koh, Biveen Shajilal +3
One of the fundamental tenets of quantum mechanics is that non-orthogonal states cannot be distinguished perfectly. When distinguishing multiple copies of a mixed quantum state, a…
Security of hybrid BB84 with heterodyne detection
Jasminder S. Sidhu, Rocco Maggi, Saverio Pascazio +1
Quantum key distribution (QKD) promises everlasting security based on the laws of physics. Most common protocols are grouped into two distinct categories based on the degrees of fr…
