The qubit encoding with low quantum-bit-error-rate (QBER) is crucial in effective quantum communications as it directly influence the final key-rate. We here introduce Mac-Zac scheme leveraging on intrinsically-stable interferometer reaching parts in 105 of base contrast.

Abstract
The qubit encoding with low quantum-bit-error-rate (QBER) is crucial in effective quantum communications as it directly influence the final key-rate. We here introduce Mac-Zac scheme leveraging on intrinsically-stable interferometer reaching parts in 105 of base contrast.
