摘      要：White-light interferometry is one of today’s most precise tools for determining the properties of optical *** achievable precision and accuracy are typically limited by systematic errors due to a high number of interdependent data-fitting ***,we introduce spectrally resolved quantum white-light interferometry as a novel tool for optical property measurements,notably,chromatic dispersion in optical *** exploiting both spectral and photon-number correlations of energy-time entangled photon pairs,the number of fitting parameters is significantly reduced,which eliminates systematic errors and leads to an absolute determination of the material *** comparing the quantum method to state-of-the-art approaches,we demonstrate the quantum advantage of 2.4 times better measurement precision,despite requiring 62 times fewer *** improved results are due to conceptual advantages enabled by quantum optics,which are likely to define new standards in experimental methods for characterising optical materials.
