Computational Complexity of Continuous Variable Quantum Key Distribution [PDF]
IEEE Transactions on Information Theory, 2008 The continuous variable quantum key distribution has been considered to have the potential to provide high secret key rate. However, in present experimental demonstrations, the secret key can be distilled only under very small loss rates. Here, by calculating explicitly the computational complexity with the channel transmission, we show that under high

Diversity space of multicarrier continuous‐variable quantum key distribution [PDF]
International Journal of Communication Systems, 2019 SummaryThe diversity space of multicarrier continuous‐variable quantum key distribution (CVQKD) is defined. The diversity space utilizes the resources that are injected into the transmission by the additional degrees of freedom of the multicarrier modulation.

Quantum Key Distribution with Continuous Variables in Optics [PDF]
, 2003 We discuss a quantum key distribution scheme in which small phase and amplitude modulations of quantum limited, CW light beams carry the key information. We identify universal constraints on the level of shared information between the intended receiver (Bob) and any eavesdropper (Eve) and use this to make a general evaluation of the security and ...
