The Japanese technology company claims that its simulator can outperform identical machines from IBM and Intel by two to one.
“We are on the cusp of a new era in computing technology,” Fujitsu CTO Vivek Mahajan claimed. “Fujitsu has successfully produced the world’s fastest quantum simulator by leveraging its world-leading knowledge in computing technologies gained over many decades.”
Fujitsu claims to have constructed a quantum computer simulator that can handle 36-qubit quantum circuits on a cluster system using the company’s PRIMEHPC FX 700 supercomputer, which is powered by the same CPU as Fugaku, the world’s fastest supercomputer.
The quantum simulator, according to Fujitsu, is made up of 64 nodes on the PRIMEHPC FX 700 and can run quantum simulator software Qualacs in parallel at high speeds, reaching about double the performance of equivalent computers from IBM and Intel.
Fujitsu has also created a mechanism for efficient rearrangement of qubit states deployed in the distributed memory on the cluster based on the progress of the quantum circuit, according to Fujitsu.
In the future, Fujitsu said it will collaborate with Fujifilm to use the quantum simulator for material science research. Fujitsu, on the other hand, plans to provide a 40-qubit simulator by September.
