Api Endpoint

HALOWERK quantumwerk

Compares caller-supplied Alice and Bob bases, retains matching-basis positions, calculates the quantum bit error rate over caller-selected revealed positions, and returns only a digest and count for remaining demonstration bits. It neither exchanges quantum states nor creates a secret key: all submitted bits are disclosed to this service and must never be used as production key material.
