We describe and benchmark a new quantum charge-coupled device (QCCD) trapped-ion quantum computer based on a linear trap with periodic boundary conditions, which resembles a race track. The new system successfully incorporates several technologies cr

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
