Modeling quantum optics for quantum key distribution system simulation

Towards the Modeling and Simulation of Quantum Key Distribution Systems

Quantum Key Distribution (QKD) is a nextgeneration security technology that exploits the properties of quantum mechanics to enable two parties to generate an unconditionally secure shared secret key. QKD is novel because its security is based upon the fundamental laws of quantum mechanics and not on computational complexity. QKD systems are composed of multiple interconnected electrical, optica...

Mixed basis quantum key distribution with linear optics

Two-qubit quantum codes have been suggested to obtain better efficiency and higher loss tolerance in quantum key distribution. Here, we propose a two-qubit quantum key distribution protocol based on a mixed basis consisting of two Bell states and two states from the computational basis. All states can be generated from a single entangled photon pair resource by using local operations on only on...

Quantum Key Distribution with Continuous Variables in Optics

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 efficiency of the scheme.
