This innovation will enable the development of a quantum computer with 10,000 physical qubits and 64 logical qubits, which equates to a peak computing performance of about 100,000 times greater than current high-performance computers.
Some experts state that the development of practical, fault-tolerant quantum computers depends on using logical qubits composed of multiple physical qubits. Researchers estimate they will need more than 1 million physical qubits to realize a fault-tolerant quantum computer.
Current quantum processors use far fewer than 10,000 physical qubits so do not offer practical fault-tolerant quantum computing.
To solve these challenges, Fujitsu and Osaka University created a new, highly effective analog rotation quantum computing architecture.
This architecture will allow quantum computers with 10,000 physical qubits to outperform current classical computers and significantly reduces the number of physical qubits needed for quantum error correction. It also serves to advance the development of accurate, fault-tolerant quantum computing.
The newly developed computing architecture will enable the development of a quantum computer with 10,000 physical qubits and 64 logical qubits, which equates to computing performance 100,000 times greater than the peak performance of conventional high-performance computers.
