    Sudden Breakups of Monogamous Quantum Couples Surprise Researchers

    January 1, 2026

    To understand the properties of materials, it’s crucial to know about the interactions of the particles inside them. A recent experiment by JQI Fellow Mohammad Hafezi and his colleagues explored a new regime of quantum interactions and revealed what happens when you break up the normally monogamous relationships between certain quantum particles.

    With Passive Approach, New Chips Reliably Unlock Color Conversion

    November 14, 2025

    Researchers at JQI have designed and tested new chips that reliably convert one color of light into a trio of hues. Remarkably, the chips all work without any active inputs or painstaking optimization—a major improvement over previous methods.

    Researchers Identify Groovy Way to Beat Diffraction Limit

    October 3, 2025

    There's a limit to how tightly a lens can focus a laser beam. For researchers studying the interactions between light and matter, this makes experiments more challenging. A new chip made from a thin, grooved sheet of silver defies this limit, delivering the energy of 800-nanometer laser light to a sample in peaks and valleys just a few dozen nanometers apart.
