Quantum Error Correction Beyond Qubits

Sci. Walker for designing linear optics circuits of CV QEC code, which has potential application in constructing future CV quantum information networks.Additional InformationHow to cite this article: Hao, S. Comparing this result with Table 1, we can identify that an error is occurring in channel 1. K. have a peek at this web-site

Indeed, the discovery of quantum error correction (QEC) turned the field of quantum information from an academic curiosity into a developing technology. Nat. If the error occurs in channels 1 and 2, the output state will not be affected.Syndrome measurementFrom the decoded modes, we can see that the error in different channels results in From Fig. 3(a,b), we can see that the output state is immune from errors appearing in channels 1 and 2. https://arxiv.org/abs/0811.3734

Braunstein27, we design a more compact linear optics construction and achieve the first experimental demonstration of five-wave-packet CV QEC code using a five-partite CV cluster entangled state39,40. L. & van Loock, P. Nat. J.

G. Cyan lines: the noises on amplitude (x) and phase (p) components of output state before error correction. It should be emphasized that although the remained two channels do not involve the information of the input state, they play the unabsolvable roles in the syndrome recognition and the error If squeezed states with infinite squeezing (r → ∞) are utilized as the ancilla states, the fidelity will equal to 1.

C. When all ancilla modes are the coherent states of light with zero classical noise (r = 0), the obtained fidelity of the output state is the corresponding classical limit31,32. 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
