Quantum cryptography using qutrits by ZDNet’s Roland Piquepaille — Physicists from the University of Wien, Austria, are testing quantum cryptography (QC) systems based on qutrits instead of the more common qubits. These qutrits can simultaneously exist in three basic states. This means that QC systems based on qutrits will inherently be more secure.
