Fujitsu and Osaka University Advance Quantum Computing with Error Reduction

Fujitsu Limited and the Center for Quantum Information and Quantum Biology at Osaka University (QIQB) have developed two new technologies for the space-time efficient analog rotation quantum computing architecture. The advancements include improvements in phase angle accuracy during phase rotation and the generation of efficient qubit operation procedures. These technologies enable a quantum computer to perform a calculation in ten hours that would take a classical computer five years, utilizing only 60,000 qubits. This is significantly fewer than the amount typically required for fault-tolerant quantum computation (FTQC), demonstrating quantum computing's potential to surpass classical computation speeds.

The research, supported by grants from the Japan Science and Technology Agency (JST), the Program on Open Innovation Platforms for Industry-academia Co-creation (COI-NEXT), "Quantum Software Research Hub," and the Japanese Ministry of Education, Culture, Sports, Science and Technology's Quantum Leap Flagship Program (MEXT Q-LEAP), suggests a significant step forward in the practical application of quantum computing. The collaboration aims to address societal issues such as decarbonization and the reduction of new material development costs, highlighting the potential of quantum computing to contribute to solving major global challenges.
