The two-photon interference mediated by the magnetic resonance in two-dimensional metamaterial

Abstract

Nowadays, the quantum information processing has been carrying out in variety of solid state systems, such as superconductors, dielectrics, and metallic nano-structures. Here, we investigated the quantum properties of magnetic resonance in a two-dimensional metamaterial with the split-hole resonator structure. The sample was placed in path of entangled photons produced from spontaneous parametric down-conversion process, and a two-photon interference was performed. Such a two-dimensional metamaterial was able to convert photons into magnetic resonances, and reradiate as photons at the other side. A Hong-Ou-Mandel dip with a visibility of 89.4 ± 6.0 % was explicitly observed, which indicated that the magnetic resonance do own a quantum nature. This will be useful for future researches at the interface between metamaterials and quantum information processing.
