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 ...

Quantum computers are both the most promising and the most confusing segment of innovation in computing. On one hand, quantum computers promise to perform calculations that would otherwise be utterly ...

The proof-of-concept still has a long way to go before it’ll end up in real devices, but it’s a great start. Reading time 3 minutes According to physicist Paul Davies, a tried-and-true “quantum” ...

One afternoon in October 1979, Gilles Brassard was swimming outside a beachfront hotel in San Juan, Puerto Rico, when a stranger swam up to him and changed the course of his career. Without so much as ...

Is there a fundamental reason why quantum computers cannot factor large integers used for encryption today? We introduce a theory of quantum physics based on the notion that the continuum nature of ...

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science. Reading time 6 minutes The use of the word “quantum” has become ...

Researchers at the University of Tuebingen, working with an international team, have developed an artificial intelligence that designs entirely new, sometimes unusual, experiments in quantum physics ...

A single trapped atom has been used to carry out Einstein’s proposed test of the double-slit experiment, a challenge he believed could expose a flaw in quantum mechanics by measuring its recoil The ...
