    Quantum networks advance with entanglement of photons, solid-state qubits

    A team of Harvard physicists led by Mikhail D. Lukin has achieved the first-ever quantum entanglement of photons and solid-state materials.  The work marks a key advance toward practical quantum networks, as the first experimental demonstration of a means by which solid-state quantum bits, or “qubits,” can communicate with one another over long distances. Quantum networking applications such as…

    Cold atoms and nanotubes come together in an atomic ‘black hole’

    Carbon nanotubes, long touted for applications in materials and electronics, may also be the stuff of atomic-scale black holes. Physicists at Harvard University have found that a high-voltage nanotube can cause cold atoms to spiral inward under dramatic acceleration before disintegrating violently. Their experiments, the first to demonstrate something akin to a black hole at…

    Laser advance could open up new markets

    Applied scientists from Harvard University have, for the first time, demonstrated high-power continuous wave (cw) room-temperature quantum cascade (QC) lasers made by a well-established mass production semiconductor synthesis technique. The breakthrough could soon lead to the large-scale commercialization of QC lasers and open up new markets for laser-based chemical sensors. The new generation of QC…

    Quantum network to deliver secure messages

    Talked about for decades, a quantum code key system joined to the Internet has now been demonstrated. It sends encoding and decoding keys as light pulses between Harvard and Boston universities and BBN Technologies, a hi-tech company in Cambridge, Mass. The network started operating in June 2004. “Our team has been able to develop a…
