Quantum Physics

  1. Animals

    A proposed ‘quantum compass’ for songbirds just got more plausible

    Quantum physics could be behind birds’ magnetic sense of direction, new measurements indicate.

  2. Quantum Physics

    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.

  3. Particle Physics

    Muon magnetism could hint at a breakdown of physics’ standard model

    After two decades, a new measurement of the muon magnetic anomaly reinforces earlier hints that its value disagrees with standard physics.

  4. Quantum Physics

    ‘Designer molecules’ could create tailor-made quantum devices

    Scientists are making molecules suited to a variety of quantum tasks by building them up, atom by atom.

  5. Quantum Physics

    Drones could help create a quantum internet

    Flying drones sent entangled particles of light to two locations a kilometer apart.

  6. Quantum Physics

    The new light-based quantum computer Jiuzhang has achieved quantum supremacy

    A second type of quantum computer has now performed a calculation impossible for a traditional computer.

  7. Quantum Physics

    Galileo’s famous gravity experiment holds up, even with individual atoms

    When dropped, two types of atoms accelerate at the same rate despite their differences, much like objects in Galileo’s leaning Tower of Pisa experiment.

  8. Quantum Physics

    A measurement of positronium’s energy levels confounds scientists

    A gap in the energy levels of positronium seems to be substantially larger than predicted, and physicists don’t know why.

  9. Quantum Physics

    To live up to the hype, quantum computers must repair their error problems

    Before quantum computers can reach their potential, scientists will need to master quantum error correction.

  10. Quantum Physics

    This weird quantum state of matter was made in orbit for the first time

    Bose-Einstein condensates made on the International Space Station could reach temperatures lower than any known in the universe.

  11. Quantum Physics

    Physicists exploit a quantum rule to create a new kind of crystal

    Cold atoms can form crystals as a result of the Pauli exclusion principle.

  12. Physics

    A newfound superconducting current travels only along a material’s edge

    In a first, scientists spot electricity flowing without resistance on the rim of a topological superconductor.
