36-qubit quantum circuits

Fujitsu claims to have developed a quantum computer simulator capable of handling 36-qubit quantum circuits on a cluster system featuring the company's supercomputer PRIMEHPC FX 700.

For those not in the know, that supercomputer has the same CPU as the world's fastest supercomputer, Fugaku.

Fujitsu said that its quantum simulator consists of 64 nodes on PRIMEHPC FX 700, and can execute quantum simulator software Qualacs in parallel at high speed, achieving approximately double the performance of other similar machines from IBM and Intel.

Fujitsu added it has further developed a method that allows the efficient rearrangement of qubit states deployed in the distributed memory on the cluster according to the progress of the quantum circuit.

Fujitsu CTO Vivek Mahajan claimed to be standing at the edge of a new age in computing technology.

“Fujitsu has successfully developed the world's fastest quantum simulator by applying its world-leading expertise in computing technologies cultivated over many decades," he said.

Looking ahead, Fujitsu said it would team up with Fujifilm to use the quantum simulator for research in material sciences. At the same time, Fujitsu is aiming to develop a 40-qubit simulator by September.

The system will be used by customers to accelerate the development of quantum applications and ultimately contribute to a sustainable world by solving a range of issues facing society, Mahjan said.
