Abstract
Quantum simulators hold promise for solving many intractable problems. However, a major challenge in quantum simulation, and quantum computation in general, is to solve problems with limited physical hardware. Currently, this challenge is tackled by designing dedicated devices for specific models, thereby allowing one to reduce control requirements and simplify the construction. Here we suggest a method for quantum simulation in circuit QED that provides versatility in model design and complete control over its parameters with minimal hardware requirements. We show how these features manifest through examples of quantum simulation of Dirac dynamics, which is relevant to the study of both high-energy physics and two-dimensional materials. We conclude by discussing the advantages and limitations of the proposed method.
