Breakthrough may clear major hurdle for quantum computers (IMAGE)
Caption
The circuit diagram on the left illustrates how the Chalmers team of researchers 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 on the right of the illustration are so called ‘Wigner negative regions’ - a clear signature of the quantum properties of the state.
