Quantum computers learn how to simulate quarks

Waterloo researchers have developed a new quantum computing approach that brings science closer to simulating the early universeBy Institute for Quantum ComputingResearchers at University of Waterloo’s Institute for Quantum Computing (IQC) have reached a milestone in quantum information science: using a quantum computer to simulate how matter can behave in extreme environments, like the early universe after the big bang.The researchers simulated a theory called quantum chromodynamics, that helps describe how quarks interact at defined matter density and temperature, key parameters for modelling large, dense physical systems.“The stability of all matter is based on this theory and describes how quarks ‘talk’ to each other. At IQC, we developed a new theoretical and experimental approach as a tool for quantum computation.” -Dr. Christine Muschik, IQC faculty and professor in the Department of Physics and Astronomy. on Waterloo News
