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

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 ...

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 ...

Yoon Auh’s company does “cryptographic logistics,” swapping ciphers on the fly, because nobody can prove quantum-resistant ...

Irrational numbers have underpinned quantum mechanics for a century. Removing them could eliminate its strangest features and ...

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, ...

I founded Xanadu to build the world’s first scalable quantum computer. Keeping the industry here may be even harder.

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 ...

But a couple of orders of magnitude colder than it is in outer space.” He’s talking about the refrigerators inside IBM’s ...

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 ...
