To date, the highest fidelity quantum logic gates between two qubits have been achieved with variations on the geometric-phase gate in trapped ions, with the two leading variants being the Molmer-Sorensen gate and the light-shift (LS) gate. Both of t

Eliminating Leakage Errors in Hyperfine Qubits

Autor: Hayes, D., Stack, D., Bjork, B., Potter, A. C., Baldwin, C. H., Stutz, R. P.

Publikováno v: Phys. Rev. Lett. 124, 170501 (2020)

Population leakage outside the qubit subspace presents a particularly harmful source of error that cannot be handled by standard error correction methods. Using a trapped $^{171}$Yb$+$ ion, we demonstrate an optical pumping scheme to suppress leakage

Subspace benchmarking high-fidelity entangling operations with trapped ions

Autor: Baldwin, C. H., Bjork, B. J., Gaebler, J. P., Hayes, D., Stack, D.

Publikováno v: Phys. Rev. Research 2, 013317 (2020)

We present a new and simplified two-qubit randomized benchmarking procedure that operates only in the symmetric subspace of a pair of qubits and is well suited for benchmarking trapped-ion systems. By performing benchmarking only in the symmetric sub
