    "abstract": "We report on a back-action evading (BAE) measurement of the photon number of\nfiber optical solitons operating in the quantum regime. We employ a novel\ndetection scheme based on spectral filtering of colliding optical solitons. The\nmeasurements of the BAE criteria demonstrate significant quantum state\npreparation and transfer of the input signal to the signal and probe outputs\nexiting the apparatus, displaying the quantum-nondemolition (QND) behavior of\nthe experiment.",
