Who says the quantum revolution is far away?
Japan has launched its first superconducting quantum computer, developed by Fujitsu and the RIKEN Research Institute. Superconducting quantum computers are now among the most common and are used by companies such as Google, IBM, and Rigetti. This design is based on superconducting circuits operating at temperatures close to absolute zero to generate qubits.
The Japanese system, hosted at the RIKEN RQC-Fujitsu Collaboration Center, includes 64 superconducting qubits on an integrated chip. The system is capable of providing 264 states of quantum superposition and entanglement, which allows calculations to be performed on scales unattainable for classical computers. However, the system will work in parallel with classical computers running quantum simulations to control its operation.
Fujitsu points out that quantum computers require significant error correction to work effectively. For now, combining a quantum computer with an HPC cluster simulating 40 qubits will help scientists assess the system's ability to reliably generate accurate results.
RIKEN and Fujitsu claim that the hybrid system has already proven to be very accurate when applying quantum algorithms to chemical calculations. The experiment with the hybrid system allowed us to calculate the ground state energy of a molecule containing 12 hydrogen atoms with higher accuracy than when using only classical algorithms.
The system is now in place, and Fujitsu and RIKEN are making it available to external companies and institutions, including Fujifilm, Tokyo Electron, Mizuho-DL Financial Technology Co. and Mitsubishi Chemical, for joint research. In addition, Fujitsu and RIKEN are already developing the technologies needed to scale the system to 1,000 qubits.
