Spanning a range of hardware platforms, the building-blocks of quantum processors are
today sufficiently advanced to begin work on scaling-up these systems into complex …

Gate set tomography (GST) is a protocol for detailed, predictive characterization of logic
operations (gates) on quantum computing processors. Early versions of GST emerged …

We demonstrate laser-driven two-qubit and single-qubit logic gates with respective fidelities
99.9 (1)% and 99.9934 (3)%, significantly above the≈ 99% minimum threshold level …

We report high-fidelity laser-beam-induced quantum logic gates on magnetic-field-
insensitive qubits comprised of hyperfine states in Be 9+ ions with a memory coherence time …

We present improvements in both theoretical understanding and experimental
implementation of the cross resonance (CR) gate that have led to shorter two-qubit gate …
