We introduce a geometric quantification of quantum coherence in single-mode Gaussian states and we investigate the behavior of distance measures as functions of different physical parameters. In the case of squeezed thermal states, we observe that re-quantization yields an effect of noise-enhanced quantum coherence for increasing thermal photon number.

    A resource theory of coherence is built for continuous position states via a measurement-induced dephasing channel whose fixed-point set contains no normal states, yielding a relative-entropy quantifier that satisfies...
