Essential theoretical tools that have been developed to assess the security of the main experimental platforms are presented (discrete- variable, continuous-variable, and distributed-phase-reference protocols).

The author revealed that quantum teleportation as “Quantum one-time-pad” had changed from a “classical teleportation” to an “optical amplification, privacy amplification and quantum secret growing” situation.
Incoherent and coherent eavesdropping in the six-state protocol of quantum cryptography

All incoherent as well as 2- and 3-qubit coherent eavesdropping strategies on the 6 state protocol of quantum cryptography are classified and it is argued that by doing so, Eve gains only a negligibly small additional information.

Quantum key distribution with trusted quantum relay

A trusted quantum relay is introduced to enable quantum key distribution links to form the basic legs in a quantum key distribution network. The idea is based on the well-known intercept/resend…
Quantum cryptography with 3-state systems.

We consider quantum cryptographic schemes where the carriers of information are 3-state particles. One protocol uses four mutually unbiased bases and appears to provide better security than…
Quantum Cryptography using larger alphabets

An increased error rate is found compared to two-dimensional systems, hence an advantage for the legitimate users to detect an eavesdropper, and an experimental realization using an interferometric setup is proposed.

A quantum seal is a way of encoding a classical message into quantum states, so that everybody can read the message error-free, but at the same time the sender and all intended readers who have some…
