  text: Lasers with high intensity generally exhibit strong intensity fluctuations
    far above the shot-noise level. Taming this noise is pivotal to a wide range of
    applications, both classical and quantum. Here we demonstrate the creation of
    intense light with quantum levels of noise even when starting from inputs with
    large amounts of excess noise. In particular, we demonstrate how intense squeezed
    light with intensities approaching 0.1 TW cm−2, but noise at or below the shot-noise
    level, can be produced from noisy inputs associated with high-power amplified
    laser sources (an overall noise reduction of 30-fold). On the basis of a new theory
    of quantum noise in multimode systems, we show that the ability to generate quantum
    light from noisy inputs results from multimode quantum correlations, which maximally
    decouple the output light from the dominant noise channels in the input light.
    As an example, we demonstrate this effect for femtosecond pulses in nonlinear
    fibres, but the noise-immune correlations that enable our results are generic
    to many other nonlinear systems in optics and beyond.

  text: The prediction and realization of topological insulators have sparked great
    interest in experimental approaches to the classification of materials1,2,3. The
    phase transition between non-trivial and trivial topological states is important,
    not only for basic materials science but also for next-generation technology,
    such as dissipation-free electronics4. It is therefore crucial to develop advanced
    probes that are suitable for a wide range of samples and environments. Here we
    demonstrate that circularly polarized laser-field-driven high-harmonic generation
    is distinctly sensitive to the non-trivial and trivial topological phases in the
    prototypical three-dimensional topological insulator bismuth selenide5. The phase
    transition is chemically initiated by reducing the spin–orbit interaction strength
    through the substitution of bismuth with indium atoms6,7. We find strikingly different
    high-harmonic responses of trivial and non-trivial topological surface states
    that manifest themselves as a conversion efficiency and elliptical dichroism that
    depend both on the driving laser ellipticity and the crystal orientation. The
    origins of the anomalous high-harmonic response are corroborated by calculations
    using the semiconductor optical Bloch equations with pairs of surface and bulk
    bands. As a purely optical approach, this method offers sensitivity to the electronic
    structure of the material, including its nonlinear response, and is compatible
    with a wide range of samples and sample environments.

  text: Far-field super-resolution fluorescence microscopy discerns fluorophores residing
    closer than the diffraction barrier by briefly transferring them in different
    (typically ON and OFF) states before detection. In coordinate-targeted super-resolution
    variants, such as stimulated emission depletion (STED) microscopy, this state
    difference is created by the intensity minima and maxima of an optical pattern,
    causing all fluorophores to assume the off state, for instance, except at the
    minima. Although strong spatial confinement of the on state enables high resolution,
    it also subjects the fluorophores to excess intensities and state cycles at the
    maxima. Here, we address these issues by driving the fluorophores into a second
    off state that is inert to the excess light. By using reversibly switchable fluorescent
    proteins as labels, our approach reduces bleaching and enhances resolution and
    contrast in live-cell STED microscopy. Using two or more transitions to off states
    is a useful strategy for augmenting the power of coordinate-targeted super-resolution
    microscopy.
