| Abstract(in English) | Quantum error correction proposed by Shor is based on an assumption that noise is localized, that is, state of a qubit is disturbed only by interaction with its local environment. However, for entangled state where the state itself does not have locality, there cannot be any such locality for noise on it. Actually, when a state is entangled, not only state of a qubit but also state of its local environment is involved in entanglement, which means if an entangled state is represented by superposition of a minimum number of unentangled states, noise on each term is different term by term, resulting in non-local noise. Though a complication is that Shor code can allow for up to two different local environment states, which makes it work with trivial examples, in general, quantum error correction is impossible. |
