ABSTRACT
We have developed optical sources for high bit rate Quantum Communications (QC) using active elements as well as passive schemes. These sources allow achieving 100 Mbps free space Quantum Key Distribution (QKD) with improved security and use components space qualifiable, the latter being an essential aspect for their deployment in space missions.

Photon-monitoring attack on continuous-variable quantum key distribution with source in middle
Motivated by a fact that the non-Gaussian operation may increase entanglement of an entangled system, we suggest a photon-monitoring attack strategy in the entanglement-based (EB) continuous-variable quantum key distribution (CVQKD) using the photon ...
Efficient entanglement purification via quantum communication bus
A scheme is proposed to implement entanglement purification for two remote less entangled photons using robust continuous variable coherent modes, called as quantum communication bus (qubus), rather than consuming expensive ancilla single-photon ...
Multicarrier continuous-variable quantum key distribution
AbstractThe multicarrier continuous-variable quantum key distribution (CVQKD) protocol is defined. In a CVQKD protocol, the information is conveyed by coherent quantum states. The quantum continuous variables are sent through a noisy quantum ...
