Secure Key Distribution by Swapping Quantum Entanglement
Daegene Song
abstract: We report two key distribution schemes achieved by swapping quantum
entanglement. Using two Bell states, two bits of secret key can be shared
between two distant parties that play symmetric and equal roles. We also
address eavesdropping attacks against the schemes.
