Quantum error correction used to actually correct errors Microsoft and Quantinuum correct problems when entangling pairs of qubits.

And that's not just true for Atom's hardware; similar things can be said for other error-correction demonstrations done on different machines. There are two ways to go beyond these current limits.

When too many errors occur the process backs up to the previous guess and takes the other path. In our example, after tracing back, the decoder would take the path dictated by a 00 input.

A new technical paper titled “Error Detection and Correction Codes for Safe In-Memory Computations” was published by researchers at Robert Bosch, Forschungszentrum Julich, and Newcastle University.

Two other established error-detection techniques are checksum (add up all the bits of the entire message, document or program and produce a single sum) and cyclic redundancy check, which operates ...

Performance: The dual-rail qubit approach focuses on high fidelity and efficiency per qubit, aiming to achieve better results with fewer qubits compared to traditional scaling methods. Application: ...

Error detection is also important to gain an insight into the quality of the data sources, observation and processing. This report discusses methods to detect and correct errors automatically, and ...
