Quantum Error Correction Protocol


Gaussian fits yield dephasing times =12.0(9), 9.1(6) and 18.2(9) ms for qubits 1, 2 and 3, respectively. (d) Deterministic entanglement of two qubits by XX stabilizer measurement and feedback. and T.H.T. Strongly enhanced photon collection from diamond defect centres under microfabricated integrated solid immersion lenses. We show that the actively error-corrected logical qubit is robust against errors and that multiple rounds of error correction prevent errors from accumulating. weblink

Realization of quantum error correction. In most codes, the effect is either a bit flip, or a sign (of the phase) flip, or both (corresponding to the Pauli matrices X, Z, and Y). H. Phys. https://en.wikipedia.org/wiki/Quantum_error_correction

If an error is modeled by a unitary transform U, which will act on a qubit | ψ ⟩ {\displaystyle |\psi \rangle } , then U {\displaystyle U} can be described Shor is also responsible for the theoretical result that put quantum computing on the map, an algorithm that would enable a quantum computer to factor large numbers exponentially faster than a A simple error-correcting code could, for instance, instantiate a single qubit of data as three physical qubits.

The complete cycle can be repeated up to six times within the shortest qubit .Active quantum error correction on a logical qubitWe now turn to quantum error correction by stabilizer measurements. Bit Flip Memory Error J. Phys. Quantum error correction is essential if one is to achieve fault-tolerant quantum computation that can deal not only with noise on stored quantum information, but also with faulty quantum gates, faulty

The first demonstration was with NMR qubits.[4] Subsequently, demonstrations have been made with linear optics,[5] trapped ions,[6][7] and superconducting (transmon) qubits.[8] Other error correcting codes have also been implemented, such as Physical Review A™ is a trademark of the American Physical Society, registered in the United States, Canada, European Union, and Japan.
