Unlike a qubit, which is a mechanical system with only two states (the classic example being 0 and 1), quDits can have multiple quantum states: for example, a high-dimensional photon can be red\u00a0<em>and<\/em>\u00a0yellow\u00a0<em>and<\/em>\u00a0green\u00a0<em>and<\/em>\u00a0blue simultaneously. This high-dimensional quantum state significantly increases the amount of information available to be stored on a single photon. So far, researchers have confirmed the realization of a quantum system with at least 100 dimensions using this approach. The use of multidimensional quDits can contribute to more accessible development of applied quantum technologies.<\/p>\n<p><strong>Authors:\u00a0<\/strong><\/p>\n<p>Michael Kues, Christian Reimer, Piotr Roztocki, Luis Romero Cort\u00e9s, Stefania Sciara, Benjamin Wetzel, Yanbing Zhang, Alfonso Cino, Sai T.
