A Universal, Low-Delay SEC-DEC-TAEC code has been introduced to protect state registers against increasingly common multi-bit errors while maintaining low latency and reduced circuit complexity [1].

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 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 paper has triggered a wave of activity in the quantum gravity community, and new quantum error-correcting codes have been discovered that capture more properties of space-time.

However, quantum computers are notoriously error-prone. Traditionally, quantum computing platforms have worked to scale up and then correct for errors afterward.

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.

The company said it is able to reduce error rates in its quantum computing capabilities by 1,000-fold thanks to four-dimensional geometric codes.
