  • Pulsed quantum states of light are a prerequisite for many quantum technologies, yet, the precise characterisation required for applications poses a challenge. The authors propose a field-correlation measurement to reconstruct pulsed quantum states of light with Gaussian phase-space statistics and beyond, comprising many modes of the electromagnetic field.

  • The properties of semiconductor quantum dots can now be controlled down to the level of single electrons and spins. These solid-state 'artificial atoms' have inspired scientists to look at them as possible building blocks for realizations of quantum computers, with unexpected consequences.

  • Valley degeneracy in carbon nanostructures can be detrimental to electron spin control and readout based on spin blockade. As a way around this problem, it is now shown how to use a combined valley–spin blockade instead.

  • Semiconducting quantum dots have been extensively investigated with the idea of using single spins for quantum computing. Whereas access to single electrons and their spins has become routine, the challenges posed by nuclear spins remain ever present.

  • The observation of long relaxation times and high-fidelity preparation promote the spin of a hole in a semiconductor quantum dot to the best position to be a contender for the role of a solid-state qubit.

  • Several solid-state defect platforms have been proposed for application as a spin-photon interface in quantum communication networks. Here the authors report spin-selective optical transitions and narrow inhomogeneous spectral distribution of V centers in isotopically-enriched SiC emitting in the telecom O-band.

  • An all-optical manipulation of the Berry phase based on stimulated Raman adiabatic passage is demonstrated in an individual nitrogen–vacancy centre in diamond. The adiabatic control is 100 times faster than that demonstrated before in atomic systems.

  • Cerebral venous thrombosis (CVT) is a rare life-threatening disease of unknown etiology. Stegner et al. show that aberrant platelet activation through cooperative signaling of CLEC-2 and GPIIb/IIIa receptors triggers foudroyant CVT in mice and shed light on the molecular pathways of the disease pathogenesis.

  • The integration of gate-defined quantum dots with superconducting resonators results in a hybrid architecture that holds promise for quantum information processing. This Review discusses recent experimental results in the field, including the achievement of strong coupling between single microwave photons and the charge and spin degrees of freedom, and examines the underlying physics.
