    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...

    A quarter century ago, the qubit was born

    John Archibald Wheeler was fond of clever phrases.

    He made the term “black hole” famous in the 1960s. He also coined the now-familiar “wormhole” and “quantum foam.” While further pondering the mystery of quantum physics at the University of Texas at Austin during the 1980s, Wheeler repeatedly uttered his favorite interrogative slogan: “How come the quantum?” And from those ponderings...

    Quantum computers are about to get real

    Although the term “quantum computer” might suggest a miniature, sleek device, the latest incarnations are a far cry from anything available in the Apple Store. In a laboratory just 60 kilometers north of New York City, scientists are running a fledgling quantum computer through its paces — and the whole package looks like something that might be found in a dark corner of a basement. The...

    Quantum satellite shatters entanglement record

    Particles of light born in space have connected two cities via a quantum link about 10 times longer than any created before.

    A quantum-communications satellite beamed photons to Earth, separating them by more than 1,200 kilometers. The feat showed that the particles of light can retain a strange type of interconnectedness, known as quantum entanglement, even when flung to opposite ends...
