A range of Wigner-negative states (IMAGE) Chalmers University of Technology Caption Illustration of the aluminum resonator to the right. The blue and red patterns show quantum mechanical states that the Chalmers researchers can create and control. Counting from the top to the bottom right, the states are: Gottesman-Kitaev-Preskill (GKP), Cubic phase state, Binomial state, Fock state and Cat state. Credit: Yen Strandqvist, Chalmers.
