Abstract
Techniques and couplers for managing coupling between qubits are presented. A coupler can be between, and connected to, a first qubit and second qubit. The coupler can comprise three Josephson junctions (JJs). The first and second JJs can be symmetrical, which facilitates creation of a first mode of oscillation and second mode of oscillation opposite of the first mode. Third JJ facilitates a division between the first and second modes. An activation status of a ZZ gate between the first and second qubits can be controlled based on excitation status of first mode and a relationship between first mode and second mode, the excitation status being based on whether a pulse is applied to the coupler. When no pulse is applied, ZZ gate is inactive and there is no coupling. When pulse is applied, first mode is in excited state activating ZZ gate, and there is a coupling between qubits.
