For decades, the solution to harder problems has been ‘build a bigger computer’— but ...

While it's no replacement for either computer, the new device is a powerful alternative for addressing some very practical ...

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...

Could our universe be expanding then shrinking back into a tiny point, reliving a kind of big bang over and over again? Probably not, according to a mathematical analysis that argues that the laws of ...

Researchers have developed a technique that makes high-dimensional quantum information encoded in light more practical and reliable. The advancement could pave the way for more secure data ...

Nearly 50 years ago, physicists floated a bold idea: our universe might be stuck in a false vacuum. This state feels stable, but deep down, it's not. Over enormous timescales, it could suddenly tip ...

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...

A team of researchers has developed a technique that makes high-dimensional quantum information encoded in light more practical and reliable. This advancement, published in Physical Review Letters, ...
