Parasitic free gate

We propose a high-fidelity and fast multi-qubit switch between on adjusted parameters to take qubits back and forth between two on and off points with the following characteristics: the off point is a static microwave-free ZZ-free idle point, and on point is a microwave-driven ZZ-free cross-resonance entangled point. We show fast and high-fidelity switching between the idle and entangled mode in a Weakly Tunable Circuit without the necessity to largely tune coupler frequency.
