This week, Google published a paper describing how a quantum computer could theoretically derive a bitcoin private key in 9 minutes, with ramifications that stretch to Ethereum, other tokens, private ...

DENVER — An urgent call comes in from the White House. But the recipient is skeptical: They need a way to verify that the message comes from the purported location. Quantum physics has a solution.

Here’s what you’ll learn when you read this story… A mind-bending theory called quantum immortality suggests that your consciousness shifts to parallel universes after you die. The theory is an ...

Electrons are influenced by a magnetic field display known as the quantum Hall effect (QHE), which helps scientists make hyper-accurate measurements. Now, scientists have observed a similar behavior ...

Taking quantum circuits from a vague academic notion to the factory floor in just over 40 years might sound daunting — even impossible. But as Yale physicist Robert Schoelkopf explains, it all came ...

There’s only a few days left in the International Year of Quantum Science and Technology, but we’re still finding plenty to celebrate here at Physics World HQ thanks to a long list of groundbreaking ...

Every year, Santa Claus races around the globe in a matter of hours to bring presents to children all over the world. This is how countless films and stories describe it, but scientists have always ...

On October 8, 2024, the field of physics was plunged into controversy. That day, the Nobel Prize in Physics was awarded for discoveries not involving black holes, cosmology, or strange new subatomic ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

GRIFFITH, Australia—At a tiny airport in the Australian countryside last month, a small plane took off carrying a device that could transform how U.S. drones, aircraft and ships navigate across future ...
