TOKYO – Fujitsu Limited today announced a breakthrough in quantum simulation technology, increasing the computational speed of a quantum-classical hybrid algorithm by 200 times. This advance represents a major advance in the early use of quantum computers, especially for complex problems in materials science and drug discovery that traditionally require hundreds of days to compute.
This new technique enables the simultaneous processing of multiple quantum circuit calculations, which are often performed repeatedly and distributed among different groups. By optimizing this process, Fujitsu was able to reduce calculation time from an estimated 200 days to just one day in one of the world's largest quantum simulators.
Quantum-classical hybrid algorithms such as the Variational Quantum (NASDAQ:) Eigensolver (VQE) are critical to the practical implementation of noisy intermediate-scale quantum (NISQ) computers capable of processing 100 to 1,000 qubits, and are currently under development. is in progress. We demonstrated the utility of quantum computing before the advent of fault-tolerant quantum computers (FTQCs).
Fujitsu's innovation lies in its distributed processing technology, which uses remote procedure calls (RPC (NYSE:)) to send quantum circuit computation jobs over the network, allowing different quantum circuits to run simultaneously. This method reduced calculation time to 1/70 compared to conventional technology.
Additionally, by analyzing large molecules using 32 qubits in a 40-qubit quantum simulator, Fujitsu found that terms with small coefficients in the formula have minimal impact on the final result. . This insight allowed the company to reduce the number of terms in the equation while maintaining accuracy, reducing computation time for quantum circuits by about 80%.
By combining these two technologies, a quantum simulation with 32 qubits distributed across 1,024 compute nodes divided into eight groups was demonstrated to be able to complete a task that previously took 200 days in one day. I did.
Industry experts have expressed hope for the acceleration of the development of quantum algorithms and their application in various fields. Mr. Yukihiro Okuno, Principal Researcher at Fujifilm Corporation, and Mr. Tsuyoshi Moriya, Vice President at Tokyo Electron Ltd., both confirmed the potential of this technology to facilitate verification of the principles of the VQE algorithm and its applicability to materials development. Commenting on sex.
Fujitsu plans to integrate this technology into its hybrid quantum computing platform for research and practical application in fields ranging from finance to drug discovery. This development is based on a press release statement from Fujitsu Limited, a global technology and services provider with a mission to build public trust through innovation.
