Quantum error correction - Wikipedia
Quantum error correction (QEC) is a set of techniques used in quantum computing to protect quantum information from errors due to decoherence and other quantum noise.
Correcting quantum errors | IBM Quantum Learning
Quantum computing has the potential to enable efficient solutions to computational tasks for which efficient classical algorithms are not known, and possibly don't exist. There are, however, very significant challenges that will need to be overcome before we can reliably implement the sorts of large-scale quantum computations we hope will one ...
A quantum computer corrected its own errors, improving its …
Sep 10, 2024 · Scientists used Quantinuum’s H2 quantum computer (chip shown) to demonstrate a new milestone in quantum error correction. For the first time, a quantum computer has …
How Quantum Computers Will Correct Their Errors
Nov 16, 2021 · Useful quantum computers will need to use an error-correction technique like the one that was recently demonstrated on a real machine. The state of a single quantum bit needs to be imprinted on nine quantum bits for the error correction to work.
[1907.11157] Quantum Error Correction: An Introductory Guide
Jul 25, 2019 · In this review, we provide an introductory guide to the theory and implementation of quantum error correction codes. Where possible, fundamental concepts are described using the simplest examples of detection and correction codes, …
How Quantum Error Correction Works? - TechBullion
Nov 27, 2024 · Quantum error correction is the foundation upon which practical, large-scale quantum computing will be built. By encoding quantum information in ways that detect and correct errors without destroying the underlying quantum state, QEC ensures the reliability and scalability of quantum systems.
Unlocking the Potential of Quantum Computing: A Developer’s …
Dec 9, 2024 · Quantum Error Correction, a critical technique for building reliable quantum computers, paves the way for reliable and powerful quantum applications.
Error correcting codes for near-term quantum computers
Aug 16, 2023 · Quantum computers must correct more kinds of errors, like phase errors which can corrupt the extra quantum information that qubits carry. Not only that, but QEC techniques must correct errors without the ability to copy unknown quantum states, and without destroying the underlying quantum state.
Azure Quantum | Quantum error correction - quantum…
Quantum error correction techniques enable the construction of logical qubits from multiple physical qubits, reducing the impact of errors on the overall computation and making it possible to scale up quantum computers.
Realization of Real-Time Fault-Tolerant Quantum Error Correction
Dec 23, 2021 · Here, we present the first experimental demonstration of a quantum error-correction code able to detect errors and fix them while a computation is taking place as well as demonstrate the ability to arbitrarily repeat such corrected quantum computation.
