"Simultaneous Control Methods in Single-Atom Quantum Computing"
Quantum computing engineers at UNSW Sydney have successfully encoded quantum information in four unique ways within a single antimony atom implanted in a silicon chip, demonstrating the ability to perform multiple control methods within the same atom. This breakthrough could address challenges in operating millions of quantum computing units within a small space. The engineers utilized the 16 quantum states of the antimony atom to achieve this feat, providing flexibility for future quantum computing chip designs. The next step for the team is to use the large computational space of the antimony atom to perform more sophisticated quantum operations and encode a 'logical' qubit within the atom, which could lead to commercially useful quantum computer hardware.
