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

摘要

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