A Los Alamos scientist has shown that quantum computers can be used to “factorize” group representations, a mathematical ...

In theory, quantum physics can bypass the hard mathematical problems at the root of modern encryption. A new proof shows how.

Researchers have successfully used a quantum algorithm to solve a complex century-old mathematical problem long considered ...

Quantum computing is widely believed to be a revolutionary new technology. In fact, it is a double-edged sword. If efficient ...

Lauda and his colleagues solve some of the problems with topological qubits by using a class of theoretical particles they ...

A new study addresses a foundational problem in the theory of driven quantum matter by extending the Středa formula to ...

Quantum information and computation is a very active interdisciplinary area between math, physics, and computer science. Quantum error correction plays a central role ...

Today’s digital security relies on one fragile truth: that breaking today’s encryption standards, using tools available today, would take centuries. Quantum computing brings a shift in this reality.

Imagine the tap of a card that bought you a cup of coffee this morning also let a hacker halfway across the world access your bank account and buy themselves whatever they liked. Now imagine it wasn’t ...

Encryption—the process of sending a scrambled message that only the intended recipient’s device can decode—allows private and public sectors alike to safeguard information. Traditional encryption uses ...

IBM’s quantum computer cracked a 6-bit ECC key—safe for now, but experts warn Bitcoin and Ethereum must prepare for quantum threats.

The Fourier transform is a mathematical operation essential to virtually all fields of physics and engineering. Although there already exists an algorithm that computes the Fourier transform in ...
