Quantum computers are shifting from lab curiosities into real machines that can already outperform classical systems on narrow tasks, and the stakes are no longer theoretical. The technology promises ...

Quantum computers have become the latest canvas for humanity’s oldest fantasy: escaping death. Startups, futurists, and speculative essays now suggest that machines built to manipulate qubits could ...

Governments and tech companies continue to pour money into quantum technology in the hopes of building a supercomputer that can work at speeds we can't yet fathom to solve big problems. Imagine a ...

The commonly used RSA encryption algorithm can now be cracked by a quantum computer with only 100,000 qubits, but the technical challenges to building such a machine remain numerous ...

The Bitcoin network took its first step towards quantum-computing resistance with the addition of BIP 360 to its repository.

Quantum computers need special materials called topological superconductors—but they’ve been notoriously difficult to create. Researchers have now shown they can trigger this exotic state by subtly ...

The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it ...

New evidence suggests a rare triplet superconductor may help quantum computers stay in sync by preserving electron spin ...
