Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means ...

Quantum machine learning is being actively explored to assess whether quantum resources can enhance learning and inference, yet major obstacles remain. Here, we discuss pressing challenges and outline ...

Researchers from the Faculty of Engineering at The University of Hong Kong (HKU) have made a significant discovery regarding ...

A quantum trick based on interferometric measurements allows a team of researchers at LMU to detect even the smallest ...

When ultraviolet light hits ice—whether in Earth's polar regions or on distant planets—it triggers a cascade of chemical reactions that have puzzled scientists for decades. Now, researchers at the ...

In the 1971 film Willy Wonka & the Chocolate Factory, Willy Wonka teleports a larger-than-life candy bar (and a small child) across the room into a television set. The idea of instantly transporting ...

A hundred years ago, Danish physicist Niels Bohr and his student German physicist Werner Heisenberg walked through Dyrehaven and along the Øresund for hours, trying to explain the strange behaviour of ...

For the past year, I kept bringing the same story to my editor: quantum computers are on the edge of becoming useful for scientific discovery. Of course, that has always been the goal. The idea of ...

Hardy's paradox, created in 1992, hinted at a scenario haunting the edges of quantum physics. It presented a thought ...

The "Oracle of Omaha" normally doesn't invest in technologies he doesn't understand. But he has done so in these two cases. Nobel Prize-winning theoretical physicist Richard Feynman once stated, "No ...

Long considered a serious technical challenge, superradiance could actually help quantum devices go even further. Quantum timekeeping comes with the paradoxes of quantum mechanics, a new study ...
