Quantum Physics

  1. Physics

    New limit placed on physics constant

    An analysis of how much the fine structure constant varies with the density of matter may help scientists determine whether the parameter changes with time.

  2. Chemistry

    Simulating reactions in cyberspace earns Nobel Prize in chemistry

    Computer models that meld quantum and classical calculations have earned three scientists the 2013 Nobel Prize in chemistry.

  3. Quantum Physics

    Quantum teleportation approaches the computer chip

    Researchers speedily transmit information from one tiny circuit to another on solid-state device.

  4. Quantum Physics

    Most precise clock

    It would take more than 50 billion years for a new atomic clock to gain or lose a second.

  5. Quantum Physics

    Light breaks up to cloak gaps in time

    Method could hide messages without sender’s knowledge.

  6. Physics

    Quantum teleportation leaps forward

    Two teams report beaming information about particles over long distances, a step toward creating satellite quantum communication networks.

  7. Quantum Physics

    New system offers way to defeat decryption by quantum computers

  8. Quantum Physics

    Like fate of cat, quantum debate is still unresolved

    Entanglement is now one of the hottest research fields in physics. It is pursued not only for insights into the nature of reality, but also for developing new technologies.

  9. Quantum Physics

    Everyday Entanglement

    Physicists are taking quantum weirdness out of the lab.

  10. Quantum Physics

    Clash of the Quantum Titans

    After decades of debate, disputes over the mathematical rules governing reality remain unresolved.

  11. Quantum Physics

    Higgs and his particle prove elusive

    Peter Higgs and colleagues receive particle theory prize; scientists still hunting the proposed boson

  12. Quantum Physics

    Quantum information teleported between distant atoms

    A team is the first to transfer a qubit, which contains quantum information, from one atom to another, a feat that could aid quantum computing and secure communication.
