Gaussian Atemporality: When Gaussian Quantum Correlations Imply Common Cause
Minjeong Song, Jayne Thompson, Matthew S. Winnel +4
Conventionally, covariances do not distinguish between spatial and temporal correlations. The same covariance matrix could equally describe temporal correlations between observatio…

Improving Gaussian channel simulation using non-unity gain heralded quantum teleportation
Biveen Shajilal, Lorcán O. Conlon, Angus Walsh +5
Gaussian channel simulation is an essential paradigm in understanding the evolution of bosonic quantum states. It allows us to investigate how such states are influenced by the env…

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…
