To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate. Scientists encode these ...

Quantum computing may one day outperform classical machines in solving certain complex problems, but when and how this “quantum advantage” emerges has remained unclear. Now, researchers from Kyoto ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...

European researchers are developing quantum computers using light and glass, in a collaboration that promises breakthroughs in computing power, battery technology and scientific discovery. Giulia ...

Classical computing has operated as the fundamental power behind our digital world for many decades. Modern civilization relies on classical systems to operate smartphones and global financial ...

Algorithms called phantom codes could help quantum computers run complex programs without errors, overcoming a big hurdle for making the technology more broadly useful. Many popular error-correcting ...
