New buried-growth process enables 2D arrays of position- and orientation-controlled diamond qubits
Researchers at Kanazawa University, in collaboration with Diamond and Carbon Applications (Germany), have developed a buried-growth process for nitrogen–vacancy (NV) centers in diamond using microwave plasma chemical vapor deposition (MPCVD). By employing nitrogen-radical selective etching, which simultaneously enhances metal-mask durability through nitridation, the team enabled a continuous etching–growth sequence within a single MPCVD process.
Advances in materials science and quantum computing research are converging to enable precise engineering of qubits, a critical step for scalability.
This breakthrough addresses a significant challenge in quantum computing by enabling uniform, scalable arrays of diamond qubits, which is crucial for building robust quantum processors.
The ability to control the position and orientation of diamond qubits during growth removes a major impediment to scaling up quantum hardware based on nitrogen-vacancy centers.
