Several years ago one of us, Toni, asked another of us, Marco, to come to his office at the Institute of Photonic Sciences, a large research center in Castelldefels near Barcelona. “There is a problem ...

The allure of quantum computers is, at its heart, quite simple: by leveraging counterintuitive quantum effects, they could perform computational feats utterly impossible for any classical computer.

Real and imaginary: The time-dependent Schrödinger equation formulated using complex numbers. (Courtesy: iStock/piranka) Complex numbers are essential to achieve the most accurate quantum-mechanical ...

Forbes contributors publish independent expert analyses and insights. Paul-Smith Goodson is an analyst covering quantum computing and AI. Let’s say you’re interested in buying a car, so you visit a ...

Here’s what you’ll learn when you read this story: Quantum computers can outperform even the best classical supercomputers thanks to quantum entanglement and superposition, but even they can’t solve ...

Researchers have achieved a major milestone in quantum computing after successfully generating “truly random” numbers using the next-generation machines. Quantum computers hold the potential to be ...

Quantum computers still can’t do much. Almost every time researchers have found something the high-tech machines should one day excel at, a classical algorithm comes along that can do it just as well ...
