Physicists at Trinity College Dublin, in collaboration with IBM, have successfully simulated super diffusion in a system of interacting quantum particles on a 27-qubit quantum computer. This breakthrough opens up possibilities for deeper insights into condensed matter physics and materials science. The research, published in the journal NPJ Quantum Information, demonstrates the potential of quantum computing in both commercial and fundamental physics inquiries. The team's work focused on simulating the long-time behavior of spin excitations in a Heisenberg chain, revealing the occurrence of super-diffusion governed by the Kardar-Parisi-Zhang equation.
Trinity College Dublin, in collaboration with IBM Dublin, has successfully simulated super diffusion in a system of interacting quantum particles on a quantum computer. This achievement marks a significant step towards performing complex quantum transport calculations on quantum hardware, which could provide new insights in condensed matter physics and materials science. The research, conducted as part of the TCD-IBM predoctoral scholarship program, utilized a 27-qubit quantum computer located in IBM's lab in New York and programmed remotely from Dublin. Quantum simulation allows for the efficient description of complex quantum systems, overcoming the limitations of classical computers. The team focused on simulating the long-time behavior of spin excitations in a Heisenberg chain, observing super-diffusive transport governed by the Kardar-Parisi-Zhang equation.
