One of the greatest mysteries of science could be one step closer to being solved.

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.
