    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.

    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.

    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.

    Physicists used LIGO’s mirrors to approach a quantum limit

    Using LIGO’s laser beams to reduce jiggling rather than detect gravitational waves, scientists have gotten closer to the realm of quantum mechanics.
