    "summary": "Finite-energy GKP states beat squeezed vacuum in the model when their envelope was broad enough, though equal photon budgets reversed the result.",
    "body_text": "The analysis compares standard coherent-plus-squeezed-vacuum interferometers with a coherent beam paired to a finite-energy Gottesman–Kitaev–Preskill state. With a sufficiently broad envelope, the multi-peak GKP resource produced better modeled phase sensitivity even in the presence of optical loss. At equal or lower mean photon number, however, squeezed vacuum performed better because the GKP envelope narrowed. Loss eventually erased either advantage as both resources approached ordinary vacuum, making energy accounting central to the proposal.",
