Quantum Physics

  1. Quantum Physics

    Gell-Mann, Hartle spin a quantum narrative about reality

    The “consistent histories” approach to quantum physics removes any role for people in creating “quasiclassical” reality.

  2. Quantum Physics

    ‘QBists’ tackle quantum problems by adding a subjective aspect to science

    Advocates of a program called “Quantum Bayesianism” take a subjective approach to resolving the paradoxes of quantum physics.

  3. Particle Physics

    Electrons’ roundness frustrates researchers

    Experiment finds no signs of asymmetry, which would point to undiscovered particles.

  4. Quantum Physics

    Quantum information storage that lasts and lasts

    Physicists have stored a snippet of quantum information at room temperature for more than 1,000 times the previous record.

  5. Physics

    Single atoms hold on to information

    Minutes-long data storage by individual atoms beats previous record of tiny fraction of a second.

  6. Quantum Physics

    Electron makes ultracold atoms move as one

    Harnessing the strong particle-gas interaction is early step toward quantum optics applications.

  7. Quantum Physics

    Single electron caught in action

    Researchers have found a way to isolate the behavior of one particle.

  8. Quantum Physics

    Heisenberg’s instinct was accurate

    Scientists develop mathematical proof of quantum physics feature first suggested more than 80 years ago.

  9. 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.

  10. 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.

  11. Quantum Physics

    Quantum teleportation approaches the computer chip

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

  12. Quantum Physics

    Most precise clock

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