<p>A shielded superconducting device (11) includes a thin-film superconducting device, such as a Josephson device (12), and an adjacent superconducting shield (13). The device is arranged to operate as superconducting device when operated at a temperature below the critical temperature of the superconducting material chosen for the device. By virtue of the adjacent location of the Josephson device and the shield element, the Josephson device is partially shielded or totally shielded from an external magnetic field (14) applied to the superconducting device, due to the Meissner effect whereby magnetic flux is wholly or partly excluded from penetrating through the shield.</p> |
