Quantum photonic system modelling on NISQ devices*

Tavis-Cummings (TC) cavity quantum electrodynamics effects, describing the interaction of N atoms with an optical resonator, are at the core of atomic, optical and solid state physics. The full numerical simulation of TC dynamics scales exponentially with the number of atoms. Here, we test the recently devised Quantum Mapping Algorithm of Resonator Interaction with N Atoms (Q-MARINA), an intuitive mapping of the singly excited open quantum TC model to a quantum circuit with linear space and time scaling, on a variety of quantum hardware from superconducting to those based on trapped ions. Finally, we benchmark the robustness of the algorithm against the quantum master equation solution on a classical computer and make the first attempts to implement quantum error mitigation techniques.
