    Seeing things in a different light

    Harvard researchers are using a chemical process known as triplet fusion upconversion to transform near-infrared photons into high-energy photons. The high-energy photons could be used in a huge range of applications, including a new type of precisely targeted chemotherapy, in which low-energy infrared lasers that penetrate deep into the body could be used to transform…

    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.

    Seeing light in a new way

    Working with colleagues at the Harvard-MIT Center for Ultracold Atoms, Professor of Physics Mikhail Lukin and post-doctoral fellow Ofer Firstenberg have managed to coax photons into binding together to form molecules — a state of matter that, until recently, had been purely theoretical.
