摘要:We study efficient quantum error correction schemes for the fully correlated channel on an n-qubit system with error operators that assume the form . In particular, when is odd, we have a quantum error correction scheme using one arbitrary qubit to protect the data state in the -qubit system. When is even, we have a hybrid quantum error correction scheme that protects a -qubit state and 2-classical bits. The scheme was implemented using Matlab, Mathematica and the IBM's quantum computing framework qiskit.

Note: Problems and results will be described in terms of elementary matrix theory. No quantum mechanics background is needed.
