Home develops trapped-ion control and oscillator encodings, helping demonstrate a logical grid-state qubit and correction cycles that prolong information stored in an ion’s motion.
International Year of Quantum Science and TechnologyarXiv / NaturearXivHome’s experimental work explores how a single oscillator can carry a protected logical qubit. His collaborations first prepared and controlled grid states in the motion of a trapped calcium ion, then demonstrated correction of small shifts in position and momentum. This connects a mathematical encoding to the physical operations needed to maintain it. The results are significant steps in quantum control and error correction, with their scope limited to the particular encoded systems and procedures tested.
