A random quantum key distribution by using Bell states
We proposed a new scheme for quantum key distribution based on entanglement swapping. By this protocol Alice can securely share a random quantum key with Bob, without transporting any particle.
متن کاملGeneralized Bell States and Quantum Teleportation
We make a brief comment on measurement of quantum operators with degenerate eigenstates and apply to quantum teleportation. We also try extending the quantum teleportation by Bennett et al [5] to more general situation by making use of generalized Bell states.

متن کاملComment on “A Random Quantum Key Distribution Achieved by Using Bell States”
In a recent paper [J. Opt. B: Quantum Semiclass. Opt. 5 (2003) 155-157], a quantum key distribution scheme based on entanglement swapping was proposed, which exhibited two improvements over the previous protocols. In this Comment, it is shown that the scheme has no properties as been discussed.
متن کاملQuantum key distribution with prepare-and-measure Bell test
The prepare-and-measure quantum key distribution (QKD) has the merits of fast speed, high key generation rate, and easy implementation. However, the detector side channel attacks greatly undermine the security of the key bits. The eavesdropper, Eve, exploits the flaws of the detectors to obtain illegal information without violating quantum principles. It means that she can intervene in the comm...
متن کاملSteering Bell-diagonal states.
We investigate the steerability of two-qubit Bell-diagonal states under projective measurements by the steering party. In the simplest nontrivial scenario of two projective measurements, we solve this problem completely by virtue of the connection between the steering problem and the joint-measurement problem. A necessary and sufficient criterion is derived together with a simple geometrical in...
