In the world of quantum computing, the Hilbert space dimension—the measure of the number of quantum states that a quantum computer can access—is a prized possession. Having a larger Hilbert space ...

A way to greatly enhance the efficiency of a method for correcting errors in quantum computers has been realized by theoretical physicists at RIKEN. This advance could help to develop larger, more ...

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 ...

IQM Quantum Computers has developed a new quantum error-correcting code that it says can reduce logical error rates by up to 1,000 times compared with the widely used ...

A multinational team has cracked a long-standing barrier to reliable quantum computing by inventing an algorithm that lets ordinary computers faithfully mimic a fault-tolerant quantum circuit built on ...

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 ...

Quantinuum has unveiled a third-generation quantum computer that could be easier to scale up than rival approaches. The US- and UK-based company Quantinuum today unveiled Helios, its third-generation ...

Microsoft released new open-source quantum development tools, expanding the Quantum Development Kit. VS Code and GitHub Copilot now play a more central role in ...
