Observation of individual spin quantum transitions of a single antiproton. Smorra, C., Mooser, A., Besirli, M., Bohman, M., Borchert, M., Harrington, J., Higuchi, T., Nagahama, H., Schneider, G., Sellner, S., Tanaka, T., Blaum, K., Matsuda, Y., Ospelkaus, C., Quint, W., Walz, J., Yamazaki, Y., & Ulmer, S. Physics Letters B, 769:1-6, Elsevier B.V., 6, 2017. Paper Website abstract bibtex © 2017 We report on the detection of individual spin quantum transitions of a single trapped antiproton in a Penning trap. The spin-state determination, which is based on the unambiguous detection of axial frequency shifts in presence of a strong magnetic bottle, reaches a fidelity of 92.1%. Spin-state initialization with > 99.9% fidelity and an average initialization time of 24 min are demonstrated. This is a major step towards an antiproton magnetic moment measurement with a relative uncertainty on the part-per-billion level.
