Phase Compensation for Continuous Variable Quantum Key Distribution
Hou-Man Chin, Darko Zibar, Nitin Jain +2
The tracking and compensation of phase noise is critical to reducing excess noise for continuous variable quantum key distribution schemes. This work demonstrates the effectiveness…
Long-distance continuous-variable measurement-device-independent quantum key distribution with post-selection
Kieran N. Wilkinson, Panagiotis Papanastasiou, Carlo Ottaviani +2
We introduce a robust scheme for long-distance continuous-variable (CV) measurement-device-independent (MDI) quantum key distribution (QKD) in which we employ post-selection betwee…
Environment-assisted bosonic quantum communications
Stefano Pirandola, Carlo Ottaviani, Christian S. Jacobsen +4
We consider a quantum relay which is used by two parties to perform several continuous-variable protocols of quantum communication, from entanglement distribution (swapping and dis…
Thermodynamics of a Quantum Annealer
Lorenzo Buffoni, Michele Campisi
The D-wave processor is a partially controllable open quantum system which exchanges energy with its surrounding environment (in the form of heat) and with the external time depend…
Machine learning aided carrier recovery in continuous-variable quantum key distribution
Hou-Man Chin, Nitin Jain, Darko Zibar +2
The secret key rate of a continuous-variable quantum key distribution (CV-QKD) system is limited by excess noise. A key issue typical to all modern CV-QKD systems implemented with…
Quantum-Enhanced continuous-wave stimulated Raman spectroscopy
R. B. Andrade, H. Kerdoncuff, K. Berg-Sørensen +3
Stimulated Raman spectroscopy has become a powerful tool to study the spatiodynamics of molecular bonds with high sensitivity, resolution and speed. However, sensitivity and speed…
