Two qudits fully entangled

Science Daily  April 20, 2023 Quantum information carriers, just like most physical systems, naturally occupy high-dimensional Hilbert spaces. Instead of restricting them to a two-level subspace, these high-dimensional (qudit) quantum systems are emerging as a powerful resource for the next generation of quantum processors. Yet harnessing the potential of these systems requires efficient ways of generating the desired interaction between them. Researchers in Austria experimentally demonstrated implementation of a native two-qudit entangling gate up to dimension 5 in a trapped-ion system. This was achieved by generalizing a recently proposed light-shift gate mechanism to generate genuine qudit entanglement in a single […]
