Prediction of Quantum Bit Candidate Structures in Aluminum Nitride through Classical-Quantum Hybrid Computing
— Material Exploration with FTQC Algorithm on an Actual Quantum Computer —
Summary
Hirofumi Nishi (General Manager, Research and Development Department, Quemix), Taichi Kosugi (Senior Researcher, same), Yuki Takei (Group Leader, Platform Laboratory for Science & Technology, Corporate Research & Development, Asahi Kasei), Shunsuke Mieda(Principal Researcher, same), Yutaka Natsume (Senior General Manager, Informatics Initiative, Digital Value Co-creation, Asahi Kasei), Takeshi Aoyagi (Senior Fellow, same), Yu-ichiro Matsushita (Project Chief, Quantum Materials Theory Project, Quantum Functional System Research Center, QST, and Project Associate Professor, School of Science, The University of Tokyo) and others performed quantum chemical calculations using hybrid computing consisting of a Quantinuum quantum computer and the supercomputer at the Institute for Solid State Physics, the University of Tokyo, and revealed the possibility that composite defects in aluminum nitride function as new qubits. In addition, they performed quantum chemical calculations for the first time in the world (as of the end of February 2025 based on a survey of published papers performed by Quemix) using an FTQC algorithm on logical qubits using QED codes on a quantum computer, demonstrating that quantum-supercomputer hybrid computing is a powerful tool in the quantum chemical calculation field and the materials informatics field.
The research results were published online in Physical Review Applied on March 10, 2025 (U.S. local time).
