Bhavesh B. Prajapati · Zenodo (CERN European Organization for Nuclear Research) · 2016
Cryptography is age old technique used for secret communication of messages. Quantum cryptography is providing cryptographic solutions based on laws of quantum physics. Quantum public key distribution is prominent solution using which two parties can communicate securely using quantum physics. Heisenberg uncertainty principle, no cloning theorem and photon polarization are used as basic properties for quantum key distribution. Photons are basic quantum particles and they are quantized for encryption. They are also known as qubits. This paper discusses concepts behind quantum key distribution and how it is secure against eavesdropper and future advances in technology.
