Probeless Vs Probe-Based Variable-Strength Eavesdropping in Quantum Key Distribution

Quantum key distribution QKD is a provably secure way of generating a secret key, which can later be used for encoding and decoding information. In this paper we analyze the effects of an eavesdropper's variable-strength measurements on QKD. Two types of measurements have been considered: i a...

Time-Bin Encoded Quantum Key Distribution over 120 Km with a Telecom Quantum Dot Source

Quantum key distribution QKD with deterministic single photon sources has been demonstrated over intercity fiber and free-space channels. The previous implementations relied mainly on polarization encoding schemes, which are susceptible to birefringence, polarization-mode dispersion and...
