Unbounded number of channel uses are required to see quantum capacity
Toby Cubitt, David Elkouss, William Matthews +3
Transmitting data reliably over noisy communication channels is one of the most important applications of information theory, and well understood when the channel is accurately mod…
High Bit Rate Continuous-Variable Quantum Key Distribution
Paul Jouguet, David Elkouss, Sébastien Kunz-Jacques
Here, we demonstrate that a practical Continuous Variables Quantum Key Distribution (CVQKD) protocol relying on the Gaussian modulation of coherent states features secret key rates…
Fundamental Finite Key Limits for One-Way Information Reconciliation in Quantum Key Distribution
Marco Tomamichel, Jesus Martinez-Mateo, Christoph Pacher +1
The security of quantum key distribution protocols is guaranteed by the laws of quantum mechanics. However, a precise analysis of the security properties requires tools from both c…
