Abstract:
Simulating relativistic quantum particles on digital quantum processors provides a concrete pathway to explore fundamental physics on quantum computers. Discrete-time quantum walks （DTQWs） and Dirac Cellular Automata （DCA） serve as standard lattice-based frameworks to model Dirac dynamics, bridging unitary discrete-time evolution with relativistic wave equations. However, realizing these models on gate-based quantum computers typically involves deep circuits. In this talk, we present the formulation and experimental implementation of discrete-time Dirac dynamics on IBM Quantum processors. We demonstrate how circuit depth can be reduced using the Quantum Fourier Transform （QFT） and dynamic circuits with mid-circuit measurements and classical feed-forward, while examining the competing impacts of gate depth reduction, measurement error, and decoherence.
