Coupling between CaWO phonons and Er dopants
Mikhael T. Sayat, Federico Pisani, Hin Lok Chang +8
We investigate the lattice dynamics of CaWO, a promising host crystal for erbium-based quantum memories, using inelastic neutron scattering together with density-functional per…
Magnetic structure of EuZnSb single-crystal thin-film
Yu Wei Soh, Hsiang Lee, Eugen Weschke +4
Magnetic topological materials are a class of compounds which can host massless electrons controlled by the magnetic order. One such compound is EuZnSb, which has recently…
Nuclear quadrupole interaction and zero first-order Zeeman transitions of Er in CaWO
Lewin Marsh, Yikai Yang, Cesare Mattiroli +5
We report microwave spectroscopy of Er doped in CaWO which reveals the hyperfine splitting of the erbium electronic ground state (, =15/2)…
Improving Free-Space Continuous Variable Quantum Key Distribution with Adaptive Optics
Mikhael T. Sayat, Marcus Birch, Michael Copeland +6
A significant performance inhibitor of free-space continuous variable quantum key distribution (CVQKD) is turbulence, which gives rise to wavefront phase and amplitude aberrations.…
Polarisation and Temperature Dependence of Er:CaWO -- Towards a Solid-State Rare-Earth Ion-Doped Quantum Memory
Mikhael T. Sayat, Trevor R. Lee, Suchit Negi +6
In the endeavour of developing quantum memories, Er:CaWO has emerged as a promising rare-earth ion-doped (REID) crystal platform due to its long optical coherence times…
Dynamic Continuous Variable Quantum Key Distribution for Securing a Future Global Quantum Network
Mikhael T. Sayat, Sebastian P. Kish, Ping Koy Lam +2
Continuous variable quantum key distribution (CVQKD) is a developing method to secure information exchange in future quantum networks. With the recent developments in quantum techn…
Update on the German and Australasian Optical Ground Station Networks
Nicholas J. Rattenbury, Joseph Ashby, Francis Bennet +22
Networks of ground stations designed to transmit and receive at optical wavelengths through the atmosphere offer an opportunity to provide on-demand, high-bandwidth, secure communi…
Mitigation of Channel Tampering Attacks in Continuous-Variable Quantum Key Distribution
Sebastian P. Kish, Chandra Thapa, Mikhael Sayat +3
Despite significant advancements in continuous-variable quantum key distribution (CV-QKD), practical CV-QKD systems can be compromised by various attacks. Consequently, identifying…
Mapping Guaranteed Positive Secret Key Rates for Continuous Variable Quantum Key Distribution
Mikhael Sayat, Oliver Thearle, Biveen Shajilal +4
Continuous variable quantum key distribution (CVQKD) is the sharing of secret keys between different parties using the continuous amplitude and phase quadratures of light. There ar…
Satellite-to-Ground Continuous Variable Quantum Key Distribution: The Gaussian and Discrete Modulated Protocols in Low Earth Orbit
Mikhael Sayat, Biveen Shajilal, Sebastian P. Kish +5
The Gaussian modulated continuous variable quantum key distribution (GM-CVQKD) protocol is known to maximise the mutual information between two parties during quantum key distribut…
Availability, outage, and capacity of spatially correlated, Australasian free-space optical networks
Marcus Birch, James R. Beattie, Francis Bennet +6
Network capacity and reliability for free space optical communication (FSOC) is strongly driven by ground station availability, dominated by local cloud cover causing an outage, an…
