2022: Quantum Computer Simulator Announcement

At the end of March 2022, Fujitsu introduced a quantum computer simulator capable of processing 36-qubit quantum circuits in a cluster system with a PRIMEHPC FX 700 supercomputer equipped with the same processor as the world's fastest Fugaku supercomputer.

According to Fujitsu, the quantum simulator consists of 64 nodes based on the PRIMEHPC FX 700 and can simultaneously run Qualacs quantum simulator software at high speed, achieving approximately twice as much performance as other similar machines from manufacturers such as IBM and Intel. In addition, it is equipped with 32 GB of memory with a high throughput of 1024 GB per second and a speed of 12.5 GB per second by connecting nodes through InfiniBand.

Fujitsu introduced the world's most powerful quantum computer simulator

{{quote 'We are now on the verge of a new era of computing. Fujitsu successfully developed the world's fastest quantum simulator, applying its advanced computing experience gained over many decades. Moving forward, we aim to use this new quantum simulator for our customers to accelerate the development of quantum applications and ultimately contribute to a sustainable world by solving a number of problems facing society, "said Fujitsu Technical Director Vivek Mahajan. }}

Fujitsu added that the company has additionally developed a method that allows you to efficiently reorder the states of qubits deployed in distributed memory in the cluster in accordance with the course of the quantum scheme. The company also announced its intention to merge with Fujifilm to use a quantum simulator for research in the field of materials science. At the same time, Fujitsu plans to develop a simulator for 40 qubits by September 2022.^[1]
