New world record in quantum computing. Fujitsu announces that it has successfully developed the fastest quantum computer simulator in the world, capable of managing 36 qubit quantum circuits on a cluster system equipped with the same CPU that powers the fastest supercomputer in the world, Fugaku (also from Fujitsu ). It will pave the way for research and development in the fields of chemistry, materials science and finance. Index of topics • The features of the new simulator • Quantum computing and sustainability The features of the new simulator The newly developed quantum simulator, explains the Japanese company, can run the quantum simulation software "Qulacs" in parallel at high speed, achieving double the performance of other quantum simulators such as those from IBM and Intel.

The new quantum simulator uses "Qulacs", one of the world's fastest quantum simulation software developed by Osaka University and QunaSys Corporation, and memory bandwidth performance has been maximized by running multiple computations simultaneously. Fujitsu is now aiming to accelerate quantum computer development efforts with the goal of obtaining a 40 qubit simulator by September and conducting joint research and development of quantum applications with clients in the finance, drug research and chemistry sectors. Quantum computing and sustainability “We are now on the verge of a new era in information technology - explains Vivek Mahajan, CEO and Cto of Fujitsu Limited -. Fujitsu has successfully developed the world's fastest quantum simulator by applying its world-leading experience in information technology cultivated over many decades. We now aim to leverage this new quantum simulator for our customers by contributing to a sustainable world and solving a number of problems facing society. " High-speed simulators using supercomputers - says Keisuke Fujii, professor at the Division of Advanced Electronics and Optical Science, Graduate School of Engineering Science, Osaka University - are of increasing importance in the development of quantum software and quantum applications on the performance of quantum computers. Qulacs, an open source software used by developers around the world, and the technology behind the "Fugaku" supercomputer, have been combined to create the world's fastest quantum simulator, which we are confident will greatly accelerate the future development of quantum software " . Quantum computers have the potential to perform highly accurate computations in the field of computational chemistry that cannot be performed by classical computers. Fujifilm, explains Yukihiro Okuno, senior researcher, Analysis Technology Center, Fujifilm "will conduct this joint research as a feasibility study for using quantum computers in materials science."

COMMENT: As I had already written in articles in Italian newspapers, all cryptography systems collapse in the face of the crito analysis of quantum computers. The fact that they talk about quantum cryptography is a glimmer of hope for populations that has no real match. The first thing that the QUANTUM COMPUTERS of the totalitarian regimes will do will be to crack all the passwords and suck all the billions accumulated in cryptocurrencies, which, as known, are based on RSA public and private key cryptography, also in canvas pants. A simple calculation of 256 raised to 31,000 as in our basic CRIPTEOS 3001 system shows that all the feats of quantum computers stop in front of invincible cryptography. However, if that were not enough, there is the version with three keys of 40 megabytes, adopted in our proposal of Real Digital Currency, which sees the calculation of 256 raised to 42 million that laughs at all the encryption algorithms developed or used by others and invites the manufacturers of quantum computers to work hard for the next three thousand years.
