This provided the impetus for researchers to develop the error detection and correction codes discussed here. Without FEC the world would be quite different.

SEC-DED: Single Error Correction-Double Error Detection codes, which can correct single-bit errors while detecting double-bit errors.

Technical Terms Quantum error-correcting codes: Codes designed to protect quantum information from errors induced by decoherence, operational faults, and other noise sources.

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.

Checkbits in computer memory refer to additional bits used in error detection and correction schemes, particularly in the context of Error-Correcting Codes. Their superconducting system uses ...

Shenzhen, May. 27, 2025––MicroAlgo Inc. (the "Company" or "MicroAlgo") (NASDAQ: MLGO), today announced efforts to improve the accuracy and reliability of quantum algorithms by exploring and ...

The solution to this is to use what are called logical qubits, which distribute quantum information across multiple hardware qubits and allow the detection and correction of errors when they occur.

One popular approach to this is called surface code correction, in which many physical qubits work as one so-called logical qubit, essentially introducing redundancy.

Now, Microsoft has pushed the envelope further, having developed error-correction codes that are applicable to many types of qubits. So has IBM, signifying broad efforts towards the same result.

For the first time anywhere, Xanadu researchers have created a single chip that embodies a powerful type of error-detection code in a pulse of laser light.
