Nuclear Physicists Demonstrate Scalable Quantum Circuits for Simulating Fundamental Physics on IBM Processors – Quantum Computing Report

Nuclear physicists have successfully performed the largest digital quantum simulation to date using IBM quantum computers, demonstrating scalable quantum circuits for preparing initial states for simulations of fundamental physics. The research, led by scientists from the InQubator for Quantum Simulation (IQuS) at the University of Washington, addresses a critical challenge in using quantum computing to solve complex problems in the Standard Model of particle physics.

The method leverages symmetries and hierarchies in length scales to create scalable quantum circuits for preparing states with localized correlations, such as the quantum vacuum and hadrons, in one spatial dimension within quantum electrodynamics. Researchers first determined the necessary circuits for small systems using classical computers, then scaled these circuits to systems of more than 100 qubits on IBM’s quantum computers.

This achievement provides a promising way to eventually perform dynamical…
