Embodiment approach

[0035] Such as figure 1 As shown, the tunable transport sub-qubit system based on the oxygen-free copper rectangular resonant cavity mainly includes: the tunable transport sub-qubit 1, the oxygen-free copper rectangular resonant cavity 2 equipped with superconducting coils, and the magnetic shield for shielding the external environmental magnetic field Barrel 3. The tunable transmission sub-qubit 1 is placed at the center of the oxygen-free copper rectangular resonator 2 to achieve maximum electromagnetic field coupling. Since the dc-SQUID is extremely susceptible to interference from external environmental magnetic fields, a low-temperature magnetic shielding tube 3 must be used to shield the external environmental magnetic fields.

[0036] Such as figure 2 As shown, the tunable transmission sub-qubit 1 is composed of a DC superconducting quantum interference device (dc-SQUID) 11 in the center and rectangular electrode dipole antennas 13 on both sides. dc-SQUID11 is a loo...
