Abstract:
Symmetrical qubits with reduced far-field radiation are provided. In one example, a qubit device includes a first group of superconducting capacitor pads positioned about a defined location of the qubit device, wherein the first group of superconducting capacitor pads comprise two or more superconducting capacitor pads having a first polarity, and a second group of superconducting capacitor pads positioned about the defined location of the qubit device in an alternating arrangement with the first group of superconducting capacitor pads, wherein the second group of superconducting capacitor pads comprise two or more superconducting capacitor pads having a second polarity that is opposite the first polarity.
