Improved Measurement-Device-Independent Quantum Key Distribution with Uncharacterized Qubits

Abstract

We propose an improved bound for the difference between phase and bit error rate in measurement-device-independent quantum key distribution with uncharacterized qubits. We show by simulations that the bound considerably increases the final key rates.
