Abstract

The present disclosure provides a quantum processor realized in a semiconductor material and method to operate the quantum processor to implement error corrected quantum computation. The quantum processor comprises a plurality of qubit elements disposed in a two-dimensional matrix arrangement. The qubits are implemented using the nuclear or electron spin of phosphorus donor atoms. Further, the processor comprises a control structure with a plurality of control members, each arranged to control a plurality of qubits disposed along a line or a column of the matrix. The control structure is controllable to perform topological quantum error corrected computation.
