Quantum processing system

Aspects of the present disclosure are directed to quantum processing systems that include a plurality of donor atom qubits in a semiconductor substrate. The system also includes a plurality of control gates configured to control donor atom qubits. The system also includes an SLQD charge sensor fabricated on/in the semiconductor substrate. The SLQD charge sensor is configured to sense a spin state of two or more donor atom qubits located within a sensing range of the SLQD charge sensor. 本公开的方面针对量子处理系统，其包括位于半导体衬底中的多个施主原子量子位。该系统还包括被配置为控制施主原子量子位的多个控制栅极。该系统还包括被制作在半导体衬底上/中的SLQD电荷传感器。SLQD电荷传感器被配置为感测位于SLQD电荷传感器的感测范围内的两个或更多个施主原子量子位的自旋状态。
