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

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

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 mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Quantum computers, systems that process information leveraging quantum mechanical effects, could soon outperform classical computers on some complex computational problems. These computers rely on ...

Long considered a serious technical challenge, superradiance could actually help quantum devices go even further.

Light is usually described using quantum mechanics when phenomena like entanglement enter the picture. But a new paper shows ...

Christine Olsson / AP STOCKHOLM — John Clarke, Michel H. Devoret and John M. Martinis won the Nobel Prize in Physics on Tuesday for research into quantum mechanical tunneling. Clarke conducted his ...

Classical computations rely on binary bits, which can be in either of the two states, 0 or 1. In contrast, quantum computing is based on qubits, which can be 0, 1, or a superposition or entanglement ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...
