A QUANTUM PROCESSOR

摘要

Abstract The present disclosure provides a quantum processor realised in a semiconductor material and method to operate the quantum processor to implement error corrected quantum computation. The quantum processor 5 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 10 or a column of the matrix. The control structure is controllable to perform topological quantum error corrected computation. C, C, 4-1 oil us 1, 11 -NR1 A l ac j P
