Quantum computers are well suited for simulating various physical and chemical processes, but
To do this, they used a 27-qubit quantumthe Q System One computer, which was created by IBM in collaboration with the University of Tokyo. Other Japanese organizations also participated in the project. One of them is the startup QunaSys, which has extensive experience in quantum computing, as well as in creating quantum models to search for new materials with well-defined properties.
In its work, QunaSys uses the theorydensity functional (DFT), in which each solid is considered as a large number of identical and interacting electrons held together by a lattice of atomic nuclei. In other words, it is the electron density distribution, which is described by the quantum Schrödinger equations. Simulation of mathematical models of this kind is very suitable for modern quantum computers.
When using classic computers, sucha simulation would take months of simulation, while a quantum computer produces final results many times faster and with higher accuracy.
