Quantum Error Correction Continuous Variable States Against Gaussian Noise

In this case, the encoded five wave packets form a five-partite linear cluster entangled state.Error-inThe five encoded wave packets constitute five quantum channels, where the errors possibly occur.

Phys. According to the standard notation for QEC code1, the presented five-wave-packet code should be expressed by [n, k, d] = [5, 1, 3], where n = 5 denote the number of used wave packets, k = 1 et al. D Phys.

  • The aim of quantum error correction (QEC) is to eliminate or, at least, reduce the hazards resulting from the imperfect channels and to ensure transmission of quantum states with high fidelity1.
