    Flipping the switch

    Harvard researchers have succeeded in creating quantum switches that can be turned on and off using a single photon, an achievement that could pave the way for the creation of highly secure quantum networks.

    In search of nature’s camouflage

    Cuttlefish, the “chameleon of the sea,” may offer researchers a model for bio-inspired human camouflage and color-changing products, some of which could be invaluable in wartime.

    Applied physics as art

    Harvard researchers spray-paint ultrathin coatings that change color with only a few atoms’ difference in thickness.

    Needle beam stays on point

    A Harvard-led team of researchers has demonstrated a new type of light beam that propagates without spreading outward, remaining very narrow and controlled along an unprecedented distance. It could greatly reduce signal loss for on-chip optical systems and may eventually assist the development of a more powerful class of microprocessors.
