摘要: We introduce quantum hypercube states, a class of continuous-variable states that are generated as orthographic projections hypercubes onto the quadrature phase space bosonic mode. In addition to their interesting geometry, display phase-space features much smaller than Planck's constant, and large volume Wigner negativity. theoretically show these make sensitive displacements at extremely small scales in way is surprisingly robust initial thermal occupation separation superposed state components. high-temperature proof-of-principle optomechanics experiment we observe, match theory, signature outer-edge vertex structure states.
