    Next-gen quantum teleportation in just 2 photons

    Researchers teleport quantum information between two photons instead of the standard three.

  2. Quantum Physics

    Major step taken toward error-free computing

    Physicists have achieved nearly perfect control over a bit of quantum information, bringing them a step closer to error-free computation.

  3. Quantum Physics

    Shor’s code-breaking algorithm inspired reflections on quantum information

    Twenty years ago, physicists met in Santa Fe to explore the ramifications of quantum information.

  4. Quantum Physics

    Excitons’ motions captured in images

    Scientists have observed how quasiparticles called excitons move.

    Quantum experts discuss the measurement problem: A transcript from 1994

    A fairly complete transcript of a discussion about quantum physics on May 19, 1994, the last day of a workshop in Santa Fe, N.M., evolves into a more general discussion of the interpretation of quantum mechanics and the quantum measurement problem.

    Robert Redford film foretold Shor’s quantum computing bombshell

    Twenty years ago, Peter Shor showed how quantum computers could break secret codes, turning the movie Sneakers from fiction to fact.

  7. Quantum Physics

    Small step taken for quantum communication

    A single atom can change the state of a photon, which may help build quantum networks.

  8. Quantum Physics

    U.S. marches to tick of new clock

    The atomic clock NIST-F2 has launched as the country’s official civilian time and frequency standard.

  9. Quantum Physics

    Finding a quantum way to make free will possible

    Maybe quantum influences from the Big Bang make humans unpredictable, permitting the possibility of free will.

  10. Quantum Physics

    Quantum timekeeping

    Recent advances in controlling the quantum behavior of particles have inspired physicists to dream of a global clock that would tell the same time everywhere. It would be hundreds of times as accurate as current atomic clocks.

  11. Quantum Physics

    Einstein was wrong about spooky quantum entanglement

    Einstein’s biggest blunder wasn’t about vacuum energy in space, but in confusing people about quantum entanglement.

  12. Quantum Physics

    History affects superfluid’s flow, study shows

    The speed to stop the stirring motion can be slower than what was need to set the fluid spinning in the first place, which shows that what happens to the current state of the superatom depends on what it has already experienced.
