Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the ...

What if the most complex problems plaguing industries today—curing diseases, optimizing global supply chains, or even securing digital communication—could be solved in a fraction of the time it takes ...

The steady tick of a clock usually feels simple and dependable. Something swings or vibrates in a controlled rhythm and marks the passing of each moment. What you rarely notice is the hidden cost ...
