Quantum error correction (QEC) can facilitate large-scale quantum computations even with relatively noisy components. Strategies for practical QEC should have good ...

One of the biggest obstacles to building a large scale quantum computer is the high qubit cost of protecting quantum information. For two-dimensional architectures, the surface code has long been the ...

A new technical paper titled “Quantum error correction below the surface code threshold” was published by researchers at Google and other collaborators.

For the first time ever, a logical qubit meets all criteria, demonstrating that Quantum Error Correction is effective. Here is the link to the research paper. Many ...
