Schematic of the optical experiment: Excitation near-infrared laser (red bottom one) - excites the nanodisk fabricated from the 3R-molybdenum disulfide flake, standing on a glass substrate. The quarter-cut-section of the disk schematically shows that incident laser excites optical resonances, that’s why we see red areas which represent higher density of electromagnetic field. This localisation alongside with the crystalline lattice broken inverse symmetry allow for effective conversion of red pump laser into blue light (doubled frequency).

The circuit diagram to the left illustrates how the Chalmers researcher team was able to turn on and off different operations by sending microwave pulses (wiggly arrow) to the control system embedded in the oscillator. The researchers used the system to generate a so-called cubic phase state which is a quantum resource for quantum error correction. The blue areas to the right are so called Wigner negative regions - a clear signature of the quantum properties of the state.
