    FIGURE 1. Sorry, the Jetson ONE personal eVTOL is sold out for 2022 and 2023. But for $92,000, you too can get in line for this commercially available flying car for 2024. Once it’s shipped from Sweden, you’ll have to assemble it yourself. Classified as an ultralight aircraft in the U.S., the Jetson ONE does not require a pilot’s license, but would be limited to rural areas.

    Startup works with Irish institute to develop life saving technology

    Peter Fretty
    Nov. 4, 2022
    Raydiant Oximetry and Tyndall National Institute team up to create a photonics based device that could represent a meaningful change childbirth.
    FIGURE 1. Schematic of the experimental setup. Both the Bell state source and polarization qubit memory are realized as all-optical loops. Polarization-resolved detection of one photon triggers the FPGA (center of the picture), which in turn controls the quantum memory by acting on an electro-optic modulator. At the output of the memory, the photons’ polarization is detected. QWP: quarter-wave plate; HWP: half-wave plate; DM: dichroic mirror; PBS: polarizing beam splitter; EOM: electro-optic modulator.
