The math behind encryption will be no match for quantum computers, forcing organizations to rethink cybersecurity. Here’s ...

The only snag was that “Shor’s algorithm”, as it is now known, required something that at the time only existed on university blackboards: a quantum computer. These days, quantum computers—which ...

Using a conventional computer and cutting-edge mathematical tools and code, physicists at the Center for Computational Quantum Physics (CCQ) at the Simons Foundation's Flatiron Institute and ...

The hardest idea in quantum mechanics to hold in a non-physicist’s head is that a thing can be in two states at once. Not ...

Quantum computers promise to outperform today's traditional computers in many areas of science, including chemistry, physics, and cryptography, but proving they will be superior has been challenging.

Quantum computing has been discussed for years, mostly as something that exists “just over the horizon.” It’s been important in theory, but still far from a day-to-day engineering reality. But now, ...

Quantum computing has long been the domain of theoretical physics and academic labs, but it’s starting to move from concept to experimentation in the real world. Industries from logistics and energy ...

Aaron Lauda has been exploring an area of mathematics that most physicists have seen little use for, wondering if it might have practical applications. In a twist even he didn’t expect, it turns out ...

Scientists may have uncovered the missing piece of quantum computing by reviving a particle once dismissed as useless. This particle, called the neglecton, could give fragile quantum systems the full ...

If you’re picturing quantum computing as a giant red button that suddenly shuts off the internet, the reality is a little less theatrical and a lot more technical than that. The main danger isn't that ...
