The controller has to do two sets of writes or reads — one for the data and one for the code, adding latency to each access. Some controllers can pack multiple codes together for sequential data, ...

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

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.

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

To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate.

A student's tweak in quantum computing code could double its ability to catch errors, piquing the interest of Amazon's quantum computing program.

By entangling vibrations within a single atom, scientists have realized a long-theorized quantum code that could make ...

For quantum computers to go from research curiosities to practically useful devices, researchers need to get their errors under control. New research from Microsoft and Quantinuum has now taken a ...

A major challenge for DNA-based information encoding strategies is the high rate of errors that arise during DNA synthesis and sequencing. Here, we describe the HEDGES (Hash Encoded, Decoded by Greedy ...
