Fujitsu Limited and the Center for Quantum Information and Quantum Biology at Osaka University (QIQB) announced the joint development of two new technologies for the space-time efficient analog rotation quantum computing architecture (*1) that will accelerate the realization of practical quantum computing. Fujitsu and QIQB have leveraged these new technologies, one that improves phase angle accuracy during phase rotation (*2) and one that automatically generates efficient qubit operation procedures, to show that it is theoretically possible for a quantum computer to perform a calculation that would take a classical computer five years, in only ten hours. The two organizations found that the calculation, a material energy estimate, would be possible using only 60,000 qubits, significantly less than the amount typically thought to be required (*3) for fault-tolerant quantum computation (FTQC) (*4) to surpass the calculation speed of classical computers. These results demonstrate for the first time how quantum advantage, i.e., quantum computers being able to solve problems faster than current classical computers, can be achieved in the early-FTQC era (*5), which is expected to arrive around 2030.  Read Article
