(PhysOrg.com) -- Quantum cryptography, which enables two parties to communicate with each other with perfect security, has begun to be implemented by some governments, banks, and other corporations with high-security requirements. However, until now, the applications of quantum cryptography have been limited to specific earth-bound scenarios due to a key requirement of quantum key distribution: that the two parties must have a shared reference frame.
