Advanced Processing Apparatus

Patent No. EP3152153 (titled "Advanced Processing Apparatus") was filed by Diraq on Jun 6, 2014. The application was issued on Jan 19, 2022.

Patent Summary

Quantum processing element for advanced computing using silicon quantum dots as qubits. The element has a confining arrangement to form quantum dots in silicon near a SiO2 interface, and a control arrangement to tune the quantum dot energy levels. This allows addressing and manipulating individual qubits using voltage gates. The interface and materials provide tunable spin properties for qubit operation. The ability to tune qubit frequency by varying the effective g-factor enables addressing multiple qubits. This silicon-based qubit design addresses challenges of scalability and stability compared to GaAs-based qubits.
