Quantum mechanics defies classical intuition, most famously through Schrödinger’s cat, where systems exist in superpositions of opposing states. Such superpositions are central to quantum technologies. Quantum ‘cat’ states have been realized in harmonic oscillators, but implementations were largely limited to Fock, displaced, or Gottesman-Kitaev-Preskill states. A different class of macroscopic superpositions, where an oscillator is squeezed along orthogonal axes so that its positional variance is simultaneously larger and smaller than the Heisenberg limit, was proposed previously but remained unrealized. Saner et al. introduce a trapped-ion hybrid spin-oscillator system enabling an experimental realization of these ‘siblings’ of Schrödinger’s cat. Image credit: Saner et al., doi: 10.1103/k1xk-yt42.
