Abstract: A superconducting quantum processor unit (QPU) comprising a resonator having a resonator frequency ?C coupled between a control qubit having a control frequency ?L and a target qubit having a target frequency ?R. The control frequency ?L is detuned from the target frequency ?R at less than a detuning gap of the resonator frequency ?C. A microwave drive applies to the resonator a resonator drive frequency ?cd at a drive strength substantially equal to a ZZ-free operating point 0 of a controlled phase for the control qubit, resonator, and target qubit to induce entanglement between the control and target qubits. The effective ZZ coupling between the control and target qubits vanishes at operating point 0. The resonator may be of either a 2D or a 3D high-coherence resonator type. Control and target qubits may be of a fixed-frequency transmon type (e.g., cross-resonance (CR) Controlled-NOT (CNOT) or adiabatic Controlled-Z (CZ)).
