Advanced materials like superconductors have the potential to change energy transport as we know it. However, their dynamics on the microscopic scale remain poorly understood as they are difficult to simulate with classical computers.
Our lab tackles this problem by using reconfigurable atom arrays, which can be controlled at the single-particle, single-quantum-state level and assembled like quantum Lego blocks to mimic these advanced materials by quantum simulation. We are pushing the frontiers of scaling up the number of quantum Lego blocks and inducing programmable interactions between them, so that we can study interesting quantum materials in the laboratory while working towards building scalable quantum computers.
