Secure communication protocols are becoming increasingly important, e.g. for internet-based
\ncommunication. Quantum key distribution (QKD) allows two parties, commonly called Alice and Bob, to
\ngenerate a secret sequence of 0s and 1s called a key that is only known to themselves. Classically,
\nAlice and Bob could never be certain that their communication was not compromised by a malicious
\neavesdropper. Quantum mechanics however makes secure communication possible. The fundamental
\nprinciple of quantum mechanics that taking a measurement perturbs the system (unless the measurement
\nis compatible with the quantum state) also applies to an eavesdropper. Using appropriate protocols
\nto create the key, Alice and Bob can detect the presence of an eavesdropper by errors in their
\nmeasurements. As part of the QuVis Quantum Mechanics Visualisation Project, we have developed a
\nsuite of four interactive simulations that demonstrate the basic principles of three different QKD
\nprotocols. The simula…<\/p>\n","protected":false},"excerpt":{"rendered":"
