Fujitsu announced yesterday that it has successfully achieved the world’s fastest computing speed with the help of an “analog quantum computer” that applies the principles of a quantum computer capable of ultra-high-speed computing.
Moreover, Fujitsu believes its simulator can achieve twice the performance of other similar devices from IBM and Intel, an achievement expected to be put into practical use within the next few years.

According to Fujitsu, it is capable of processing 36-qubit quantum circuits on a cluster system featuring Fujitsu’s FUJITSU supercomputer PRIMEHPC FX 700 (PRIMEHPC FX 700), which is equipped with the same technology as the world’s fastest supercomputer, Fugaku. A64FX CPU.
Based on this breakthrough, from April 1, 2022, Fujitsu and Fujifilm Corporation will initiate joint research on quantum computing applications in the field of materials science.
Fujitsu also said it would speed up the development of quantum computers, with the goal of developing a 40-qubit analog computer by September 2022 and co-developing quantum applications with customers in fields such as finance and drug discovery.
Furthermore, this simulation computer is actually a parallel distributed quantum simulator developed by Fujitsu for a cluster system consisting of 64 nodes on the PRIMEHPC FX 700.
According to reports, the PRIMEHPC FX 700 is equipped with the same A64FX CPU as the supercomputing Fugaku, which can perform a theoretical peak performance of 3.072 teraflops (TFLOPS) in double-precision floating-point format calculations.
It uses 32 GB of memory and can reach 1024 GB per second high bandwidth, connected via InfiniBand nodes, at speeds up to 12.5 GB per second.
This 36 Qubit quantum simulator uses “Qulacs”, one of the fastest quantum simulator software in the world developed by Osaka University and QunaSys Corporation, and maximizes utilization by performing multiple calculations simultaneously using SVE (Scalable Vector Extensions) performance of memory bandwidth.
Of course, the new system is also compatible with other quantum simulator software besides “Qulacs”. In addition, Fujitsu has designed and developed a new method to rearrange the states of qubits in distributed memory deployed on a cluster according to the progress of quantum circuits and their calculation results, which can help reduce communication costs.
