Quantum cryptography is, in principle, a foolproof way to prevent hacking. It ensures that any attempt by an eavesdropper to read encoded communication data will lead to disturbances that can be detected by the legitimate users. Therefore, quantum cryptography allows the transmission of an unconditionally secure encryption key between two users, “Alice” and “Bob,” in the presence of a potential hacker, “Eve.” The encryption key is communicated using light signals and is received using photon detectors. The challenge is that Eve can intercept and manipulate these signals.
