Google produced the world's first quantum computer simulation of a chemical reaction

Google's science team was the first in the world to use a quantum computer to simulate a chemical reaction. Of course, the simulated response is quite simple, but it is the first significant step towards the practical use of quantum computers.

By and large, atoms and molecules are systems governed by quantum mechanics. In this regard, scientists suggest that a quantum computer will be an excellent tool for accurate modeling of these processes.

Modern quantum computers use bits or qubits to store information and perform computations.

But so far, quantum computers have not been distinguished by the high accuracy of calculations, which is indispensable for calculating complex atomic structures and, moreover, chemical reactions.

Corporation Engineers Google in their work used a device called Sycamore to perform the world's first accurate quantum simulation of a chemical reaction.

This setup is famous for gaining quantum supremacy back in 2019 when it performed calculations that were impossible on a simple computer in a reasonable amount of time.

The latest achievement Sycamore became the process of modeling a diazene molecule, which consists of a pair of nitrogen atoms and a pair of hydrogen atoms. It is these atoms that react and hydrogen forms various configurations around nitrogen atoms.

The experiment carried out on a quantum computer was carried out with the coordination of the process on classical computers in order to check the correctness of the work performed.

The results of the experiment were assessed as follows by the representative of the company R. Babbush:

"Although the calculations of the considered reaction may only need a pen and a blank sheet of paper, but in order to demonstrate the entire conversion process, you still need a computer complex."

At the moment, the company's engineers are working on quantum calculations of chemical reactions on a fundamentally different scale.

And as it turned out, to scale the process, you just need to increase the number of qubits involved in the simulation and minor changes in the algorithm.

Scientists dream that there will soon be such advances in research and modeling that it will be possible to develop new chemicals thanks to quantum computers.
