High-fidelity quantum logic gates using trapped-ion hyperfine qubits

High-fidelity quantum logic gates using trapped-ion hyperfine qubits

We demonstrate laser-driven two-qubit and single-qubit logic gates with fidelities 99.9(1)% and 99.9934(3)% respectively, significantly above the ≈ 99% minimum threshold level required for faulttolerant quantum computation, using qubits stored in hyperfine ground states of calcium-43 ions held in a...
