Limits for quantum computers: Perfect clocks are impossible, research finds

There are different ideas about how quantum computers could be built. But they all have one thing in common: you use a quantum physical system—for example, individual atoms—and change their state by exposing them to very ...

Predicting earthquakes and tsunamis with fiber-optic networks

Geophysicists at ETH Zurich have shown that every single wave of a magnitude 3.9 earthquake registers in the noise suppression system of fiber-optic networks. This method, now published in Scientific Reports, can be used ...

Boomerang-like beams of light: Research makes progress toward observing quantum backflow in two dimensions

Researchers at the University of Warsaw's Faculty of Physics have superposed two light beams twisted in the clockwise direction to create anti-clockwise twists in the dark regions of the resultant superposition. The results ...

Europe's quantum decade extends into space

Europe—and the world—is in the midst of the "quantum decade": a period in which the peculiar properties of matter that manifest at the very tiniest of scales are being transformed from mere scientific curiosities into the ...

Photonics team develops high-performance ultrafast lasers that fit on a fingertip

Lasers are essential tools for observing, detecting, and measuring things in the natural world that we can't see with the naked eye. But the ability to perform these tasks is often restricted by the need to use expensive ...

Late not great—imperfect timekeeping places significant limit on quantum computers

New research from a consortium of quantum physicists, led by Trinity College Dublin's Dr. Mark Mitchison, shows that imperfect timekeeping places a fundamental limit to quantum computers and their applications. The team claims ...

Space rocks and asteroid dust are pricey, but these aren't the most expensive materials used in science

After a journey of seven years and nearly 4 billion miles, NASA's OSIRIS-REx spacecraft landed gently in the Utah desert on the morning of Sept. 24, 2023, with a precious payload. The spacecraft brought back a sample from ...

Quantum repeaters use defects in diamond to interconnect quantum systems

The popular children's game of telephone is based on a simple premise: The starting player whispers a message into the ear of the next player. That second player then passes along the message to the third person and so on ...
