Chinese researchers have built a quantum computer that successfully simulates the complex behavior of electrons in a solid-state material.
The team leveraged machine learning and prior research on Fermi superfluids to overcome the challenges of simulating the Hubbard model.A Chinese research team has achieved a significant milestone in quantum computing by successfully building a device that can simulate the movement of electrons within a solid-state material.Understanding electron behavior is crucial for scientific advancements, particularly in the fields of magnetism and high-temperature superconducting materials.
For reference, the second stage of quantum computing focuses on developing specialized quantum simulators. These simulators are designed to tackle specific scientific problems that are too complex for classical computers to handle efficiently.The research team focused on simulating the fermionic Hubbard model . It is a theoretical model describing electron motion within lattices, proposed by British physicist John Hubbard in 1963.
Besides, there is no exact solution for this model in two or three dimensions, and even the most powerful supercomputers struggle to explore its full parameter space due to high computational demands.that simulating the movement of 300 electrons using classical computers would require storage space exceeding the total number of atoms in the universe.
