Key rate for calibration robust entanglement based BB84 quantum key
distribution protocol    [PDF]

Oleg Gittsovich, Tobias Moroder

We apply the approach of verifying entanglement, which is based on the sole knowledge of the dimension of the underlying physical system to the entanglement based version of the BB84 quantum key distribution protocol. We show that the familiar one-way key rate formula holds already if one assumes the assumption that one of the parties is measuring a qubit and no further assumptions about the measurement are needed.
