Digital Quantum Simulators Can Be Astonishingly Robust

By IQT News posted 21 May 2019

(Phys.org) Heidelberg University physicist Dr. Philipp Hauke and colleagues from Dresden and Innsbruck (Austria) have demonstrated that quantum simulations can be more robust and hence much more stable than previously assumed.
The research showed that digital quantum simulation can deliver astonishingly precise results using unexpectedly large Trotter steps. “A simulation that can predict the behaviour of many quantum particles over a longer time therefore becomes more and more likely. This further opens the door for practical applications, ranging from materials science and quantum chemistry to issues in fundamental physics,” states Dr. Hauke, who heads the “Quantum optics and quantum many-body theory” research group.
