        According to the physicists organization network reported on November 11, Canadian and British scientists have simulated the basic quantum particle - baryon - on a quantum computer for the first time, and the latest research enables scientists to study neutron stars with quantum simulation, learn more about the early universe, and explore more revolutionary potential of quantum computers。

      Christina Muske, a researcher at the Institute for Quantum Computing at the University of Waterloo in Canada, said: "This is the first time that scientists have simulated baryons on a computer, and quantum computers may one day allow us to simulate the interactions between these particles.。Instead of colliding particles in accelerators, scientists may be able to simulate these interactions on quantum computers to study the origins of the universe, for example。”

      The Quantum Interaction Group, led by Musk, focuses on quantum simulations of lattice gauge theory。These lattice gauge theories are primarily used to describe physical theories including the Standard Model of particle physics。The more fields, forces, particles, spatial dimensions, and other parameters a gauge theory encompasses, the more complex it becomes and the more difficult it is to model using classical supercomputers。

      In the latest study, Muske's IQC team, in collaboration with Randy Reeves of the University of York in the United Kingdom, developed a resource-efficient quantum algorithm that allows them to perform simple simulations of some fundamental physics and matter on IBM's cloud quantum computer and classical computers。They simulated the elementary particle baryon for the first time。

      Baryons are made of quarks, a type of elementary particle that scientists believe can no longer be divided, and to which protons and neutrons belong。The researchers note that with this landmark step, they are opening a path to simulating gauge theory with quantum computers that are far beyond the capabilities of the world's most powerful supercomputers today。

      Jinglei Zhang, a postdoctoral fellow in the Department of Physics and Astronomy at the University of Waterloo, said: "One of the exciting things about these results for us is that in the future we can consider simulating matter at higher densities that are beyond the capabilities of classical computers。”

      As scientists continue to develop more powerful quantum computers and algorithms, they will be able to simulate more complex physical phenomena, revealing secrets about the universe that even the best supercomputers have been unable to do so far, the researchers noted。
