  • Quantum-dot-based single photon sources represent a promising resource for future quantum networks. Here, the authors realize all-photonic quantum teleportation using photons from two remote near-infrared-emitting quantum dots, using polarization-preserving quantum frequency converters to enable two-photon interference at telecom wavelength.

  • Thermally activated defects in a blue-emitting phosphor can enhance energy transfer to the activator, and compensate for thermal quenching.

  • Broadband near-infrared (IR) light-emitting diodes (LEDs) are desirable for smart devices and bio-imaging applications, but the efficiency is limited by the phosphor materials. The authors report broadband emission in Eu-Tb co-doped CaS due to metal-to-metal charge transfer between dopants, and build a broadband near-IR LED with output surpassing the state of the art.

  • Serology is an important way to monitor SARS-CoV-2 infection in the population and support vaccine development. Here the authors develop a multiplex immunoassay including spike and nucleocapsid proteins of SARS-CoV-2 and the endemic human coronaviruses with high specificity and sensitivity.
