    A device consisting of a metallic island connected to electrodes via tunable semiconductor-based conduction channels is used to explore the evolution of charge quantization in the presence of quantum fluctuations; the measurements reveal a robust scaling of charge quantization as the square root of the residual electron reflection probability across a quantum channel, consistent with theoretical predictions.

    Placing a light emitter in an ultra-small optical cavity results in coupling between matter and light, generating new forms of emission that can be exploited in practical or fundamental applications; here, a system is described in which strong light–matter coupling occurs at room temperature and in ambient conditions by aligning single dye molecules in the optical cavities between gold nanoparticles and surfaces.

    A new type of device, the band-to-band tunnel transistor, which has atomically thin molybdenum disulfide as the active channel, operates in a fundamentally different way from a conventional silicon (MOSFET) transistor; it has turn-on characteristics and low-power operation that are better than those of state-of-the-art MOSFETs or any tunnelling transistor reported so far.

    A position sensor is demonstrated that is capable of resolving the zero-point motion of a nanomechanical oscillator in the timescale of its thermal decoherence; it achieves an imprecision that is four orders of magnitude below that at the standard quantum limit and is used to feedback-cool the oscillator to a mean photon number of five.
