    "abstract": "We present a method of measuring expectation values of quadrature moments of\na multimode field through two-level probe ``homodyning\u0027\u0027. Our approach is based\non an integral transform formalism of measurable probe observables, where\nanalytically derived kernels unravel efficiently the required field information\nat zero interaction time, minimizing decoherence effects. The proposed scheme\nis suitable for fields that, while inaccessible to a direct measurement, enjoy\none and two-photon Jaynes-Cummings interactions with a two-level probe, like\nspin, phonon, or cavity fields. Available data from previous experiments are\nused to confirm our predictions.",
