The Fastest Quantum Simulator of World Operates at the Atomic Level

This research has been executed by some top names of the industry and is a result of long-term hard work of scientists belonging to different Universities. Kenji Ohmori from the Institute for Molecular Science, National Institutes of Natural Sciences, Japan has associated with Matthias Weidemuller from University of Heidelberg, Claudiu Genes from the University of Innsbruck, Guiod Pupillo from the University of Strasbourg and their team members have worked together to develop such an amazing and fastest device of the world.

The world’s fastest simulator can simulate the quantum mechanical dynamics of a big number of particles networking with each other within one billionths of a second.

The dynamics related to numerous electrons linking with each other governs a range of vital chemical and physical procedure, like magnetism, superconductivity and chemical reactions. An ensemble of numerous particles thus linking with each other is considered to as a ‘robust correlated system’. A better comprehension of the properties of robustly correlated systems is thus one of the core goals of modern sciences.

It is highly problematic, however, to analyse theoretically the features of a robustly correlated system even if one utilized the post-K supercomputer that is one of the biggest and world’s fastest supercomputers intended to be completed by the year 2020 in an on-going project in Japan.

For instance, the post-K cannot precisely estimate even the energy, which is the most premium property of matter when the total number of particles in the system is almost more than 30. Despite estimating with a traditional computer like the post-K a substituting concept has been referred and proposed to as ‘quantum simulator’ in which quantum mechanical particles like atoms are organized into an artificial strongly correlated system who features are controllable and known.

The latter is the utilized to comprehend and simulate the properties of a distinct robustly correlated system whose properties are hidden. Big investment to the development of quantum simulators has hence been instigated recently in national projects of multiple countries comprising EU, US and China. The group has introduced an absolutely novel quantum simulator that can simulate the dynamics of a robustly correlated system of more than 40 numbers of atoms within one billionths of a second. It has been realized by developing a new approach in which an ultra-short laser pulse whose pulse-width is just 100 billionths of a second is utilized to regulate a high-density ensemble of atoms settled down to temperatures nearer to absolute zero. Moreover, they have succeeded in simulating the movement of electrons of this robustly correlated system that is styled by altering the strength of interactions among numerous atoms in the ensemble.

Conclusion

Such ‘ultrafast quantum simulator’ is expected to cater as a basic tool to identify the origin of physical properties of matter comprising magnetism and also superconductivity.
