Quantum Physics

  1. Quantum Physics

    Quantum physics exponentially improves some types of machine learning

    It wasn’t entirely clear if quantum computers could improve machine learning in practice, but new experiments and theoretical proofs show that it can.

  2. Quantum Physics

    A new gravity sensor used atoms’ weird quantum behavior to peer underground

    Quantum sensors promise to be more accurate and stable in the long run than other gravity probes.

  3. Quantum Physics

    ‘From Data to Quanta’ defends Niels Bohr’s view of quantum mechanics

    In his new book, philosopher Slobodan Perović corrects misconceptions about physicist Niels Bohr’s work.

  4. Quantum Physics

    The quantum ‘boomerang’ effect has been seen for the first time

    Jostled particles return to their starting points in certain materials, an experiment reveals, confirming theoretical predictions.

  5. Quantum Physics

    Quantum particles can feel the influence of gravitational fields they never touch

    A quantum phenomenon predicted in 1959, the Aharonov-Bohm effect, also applies to gravity.

  6. Quantum Physics

    A century of quantum mechanics questions the fundamental nature of reality

    A century after the quantum revolution, a lot of uncertainty remains.

  7. Quantum Physics

    Quantum physics requires imaginary numbers to explain reality

    Quantum theory based only on real numbers fails to explain the results of two new experiments.

  8. Quantum Physics

    Physicists have coaxed ultracold atoms into an elusive form of quantum matter

    Quantum spin liquids could be used to help protect fragile information in quantum computers.

  9. Quantum Physics

    Scientists finally detected a quantum effect that blocks atoms from scattering light

    When all available quantum states are full, atoms can’t scatter light, thanks to the Pauli exclusion principle, new experiments show.

  10. Quantum Physics

    Scientists are one step closer to error-correcting quantum computers

    In a quantum computer made with trapped ions, multiple quantum bits were combined into one to detect mistakes.

  11. Quantum Physics

    One of nature’s key constants is much larger in a quantum material

    The fine-structure constant is 10 times its normal value in the material, giving a peek into what physics in an alternate universe could look like.

  12. Physics

    New ‘vortex beams’ of atoms and molecules are the first of their kind

    Twisted beams of atoms and molecules join other types of corkscrew beams made of light or electrons.
