Abstract
Devices and/or computer-implemented methods facilitating suppression of spectator effects between qubits are provided. In an embodiment, a device can comprise a tunable-coupler qubit (TCQ), wherein a middle pad of the TCQ is coupled to a first capacitively-shunted flux qubit (CSFQ) coupler and wherein outer pads of the TCQ are coupled to a second CSFQ coupler; a first superconducting qubit coupled to the first CSFQ coupler; and a second superconducting qubit coupled to the second CSFQ coupler.
