Abstract
The present disclosure in some embodiments provides a method and an apparatus for providing a quantum cryptographic key distribution stabilization, which can quickly and efficiently compensate for an error caused by a temperature change, a change in polarization of a transmission path of an optical system included in a quantum cryptographic key distribution system in a cost-effective manner working perfectly with the very conventional quantum cryptographic key distribution system.
