  • Nobel Prize medal

    The 2022 Nobel Prize in Physics has been awarded to Alain Aspect, John F. Clauser and Anton Zeilinger for their experiments exploring the nature of entangled photons, in particular tests of the Bell inequalities and the demonstration of quantum teleportation. To celebrate the prize, Springer-Nature has created a collection of seminal papers and relevant content from nature.com .

  • Researchers use zinc-doped CuInSe2 nanocrystals as an alternative to lead chalcogenides for near-infrared upconversion. Upconversion to yellow with an external quantum efficiency reaching 16.7% is achieved, which can also be merged with photoredox catalysis for rapid solar synthesis.

  • A hyperspectral camera based on a random array of CMOS-compatible Fabry–Pérot filters is demonstrated. The hyperspectral camera exhibits performance comparable with that of a typical RGB camera, with 45% sensitivity to visible light, a spatial resolution of 3 px for 3 dB contrast, and a frame rate of 32.3 fps at VGA resolution.

  • The combination of optical phase conjugation and light amplification enables wavefront shaping with simultaneously optimized operational speed, number of control degrees of freedom and energy of the focused wavefront. Shaping with a 10 μs latency time over about 106 control modes and energy gain approaching unity is demonstrated.
