To circumvent this difficulty, Markus Müller's research group has established a method that allows the quantum computer to switch back and forth between two correction codes in an error-tolerant ...

More information: Quantum error correction below the surface code threshold, Nature (2024).DOI: 10.1038/s41586-024-08449-y. Provided by Nature Publishing Group ...

A quantum computer corrected its own errors, improving its calculations . It’s a step in the right direction for reliable quantum computing ...

Instead, a quantum error-correction scheme must be used. This usually involves encoding a bit of quantum information into an ensemble of qubits that act together as a single “logical qubit”. One such ...

There are similarities and differences between what the company is talking about today and IBM's recent update of its roadmap ...

Additional qubits can be used as sensors to detect errors and allow interventions to correct them. Recently, there have been a number of demonstrations that logical qubits work in principle .

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 ...

The new technique, outlined in a preprint on arXiv, comes from the same family of error-correction approaches as the surface code. ... Researchers Used a One-Atom Quantum Computer to Simulate ...

Three startups have announced error-correction breakthroughs that could accelerate enterprise adoption of quantum computing. Topics Spotlight: AI-ready data centers ...

IBM’s vision for its large-scale fault-tolerant Starling quantum computer. IBM. IBM has just made a major announcement about its plans to achieve large-scale quantum fault tolerance before the ...
