Native CCZ Gate with Fluxonium Qubits and a Microwave-Driven Coupler

Grigoriy S. Mazhorin, Tatyana A. Chudakova, Alena S. Kazmina +12

Native multi-qubit gates could reduce the overhead associated with decompositions into single- and two-qubit operations, but whether they can simultaneously provide high fidelity,…
