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…
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…
Verifying the security of a continuous variable quantum communication protocol via quantum metrology
Lorcan O. Conlon, Biveen Shajilal, Angus Walsh +4
Quantum mechanics offers the possibility of unconditionally secure communication between multiple remote parties. Security proofs for such protocols typically rely on bounding the…
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…
Single-Phonon Addition and Subtraction to a Mechanical Thermal State
Georg Enzian, John J. Price, Lars Freisem +5
Adding or subtracting a single quantum of excitation to a thermal state of a bosonic system has the counter-intuitive effect of approximately doubling its mean occupation. We perfo…
