Microwave-driven same-species sympathetic cooling for trapped ions

M. C. Smith, E. Vandrey, A. D. Leu +5

Sympathetic cooling of data qubits by coolant ions is an essential technique for trapped-ion quantum computing. Conventionally a second ion species is used, requiring additional la…

Single-qubit gates with errors at the $1 0^{- 7}$ level

M. C. Smith, A. D. Leu, K. Miyanishi +2

We report the achievement of single-qubit gates with sub-part-per-million error rates, in a trapped-ion $^{43}$ Ca $^{+}$ hyperfine clock qubit. We explore the speed/fidelity trade-o…
