Scalable Quantum Circuits for Simulating Quantum Field Theories

ORAL

Abstract

In order to approach the continuum and infinite volume limits, quantum simulations of lattice field theories require scalable quantum algorithms that can be efficiently tuned and implemented. I will discuss the hybrid Scalable-Circuit ADAPT-VQE algorithm that has been developed for state preparation in confining lattice gauge theories, and show results obtained using more than 100 qubits of IBM's quantum computers.
