Modeling quantum light interference on a quantum computer

Modeling of photonic devices traditionally involves solving the equations light–matter interaction and light propagation. Here, we demonstrate an alternative modeling methodology by reproducing optical device functionality using a quantum computer. As illustration, simulate interference on thin absorbing film. Such can lead to either perfect absorption or total transmission through film, phenomena attracting attention for data processing applications in classical information networks. We map behavior photon experiment evolution state transmon, superconducting charge qubit IBM Details real are flawlessly reproduced argue that superiority this shall be apparent complex multi-photon devices.
