Abstract: A quantum processing system and method of operating the same are disclosed. The system includes a first qubit comprising a first unpaired electron bound to a first pair of donor clusters embedded in a semiconductor substrate at a distance from the semiconductor surface. each donor cluster in the first pair of donor clusters including at least one donor atom. The system further includes a second qubit comprising a second unpaired electron bound to a second pair of donor clusters embedded in the semiconductor substrate at a distance from the semiconductor surface. each donor cluster in the second pair of donor clusters including at least one donor atom. In addition, a microwave resonator is located between the first qubit and the second qubit, wherein a first end of the microwave resonator is coupled to the first qubit and a second end of the microwave resonator is coupled to the second qubit. A photon of the microwave resonator couples the first qubit and the second qubit.

Abstract: A magnetic element includes a core, a coil and a magnetic shield. The coil is wound around the core. The magnetic shield that contains a Fe-based powder is used to cover the coil and at least a part of the core so as to reduce the noise interference on the magnetic element.
