    Light’s weird dual nature weathers trip to space and back

    Light is two-faced: Sometimes it behaves like a wave, sometimes like a particle. Now, scientists have shown that light’s shifty disposition persists even after trekking thousands of kilometers into space and back again, researchers report October 25 in Science Advances.

    Depending on how light is measured, it can either be particle-like, lighting up a camera pixel, for example, or...

    Quantum mysteries dissolve if possibilities are realities

    When you think about it, it shouldn’t be surprising that there’s more than one way to explain quantum mechanics. Quantum math is notorious for incorporating multiple possibilities for the outcomes of measurements. So you shouldn’t expect physicists to stick to only one explanation for what that math means. And in fact, sometimes it seems like researchers have proposed more “interpretations” of...

    Quantum video chat links scientists on two different continents

    Hackers, take notice: Ultrasecure quantum video chats are now possible across the globe.

    In a demonstration of the world’s first intercontinental quantum link, scientists held a long-distance videoconference on September 29 between Austria and China. To secure the communication, a Chinese satellite distributed a quantum key, a secret string of numbers used to encrypt the video...

    A new test of water ripples supports the idea of quantum heat in a vacuum

    Empty space might feel hot to a traveler zipping through at a rapidly increasing clip — or so some physicists predict. And a new experiment provides a hint that they might be right.

    That idea, known as the Unruh effect, seems to be supported by an analogous effect that appears in a tank of rippling water. Patterns in the waves, when analyzed as if seen by an accelerating observer, appear...

    Minuscule jitters may hint at quantum collapse mechanism

    A tiny, shimmying cantilever wiggles a bit more than expected in a new experiment. The excess jiggling of the miniature, diving board–like structure might hint at why the strange rules of quantum mechanics don’t apply in the familiar, “classical” world. But that potential hint is still a long shot: Other sources of vibration are yet to be fully ruled out, so more experiments are needed.

    Tiny quantum storage device fits on a chip

    A newfangled data storage device, which takes up less than a millionth the amount of space of its predecessors, could be a key component of futuristic communication systems.

    Scientists fashioned a tiny crystal that stores snippets of quantum information — which unlike computer data “bits” that come only in 0s and 1s, can also exist as both 0 and 1 simultaneously. This crystal is the...

    Modern-day Alice trades looking glass for wormhole to explore quantum wonderland

    If Lewis Carroll were alive today, he wouldn’t bother with a looking glass. His book would be called Alice Through the Wormhole.

    Being the mathematician that he was, Carroll (aka Charles Dodgson) would have kept current with the latest developments in quantum physics. He would no doubt be intrigued by a new paper describing an idea for the creation (or at least the simulation) of a...

    Quantum tunneling takes time, new study shows

    Quantum particles can burrow through barriers that should be impenetrable — but they don’t do it instantaneously, a new experiment suggests.

    The process, known as quantum tunneling, takes place extremely quickly, making it difficult to confirm whether it takes any time at all. Now, in a study of electrons escaping from their atoms, scientists have pinpointed how long the particles take...

    China’s quantum satellite adds two new tricks to its repertoire

    A record-breaking quantum satellite has again blown away the competition, achieving two new milestones in long-distance quantum communications through space.

    In June, Chinese researchers demonstrated that the satellite Micius could send entangled quantum particles to far-flung locations on Earth, their properties remaining intertwined despite being separated by more than 1,200 kilometers...
