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

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 ...

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP ...

A theorem states that no correction code can implement all the gate operations required for freely programmable computations with the logical quantum bits easily and protected against errors.

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.

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 ...

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.

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.
