D.5 Quantum error correction - UTK-EECS
... is used to correct X errors, and triple redundancy again to correct Z errors, thus requiring nine code qubits for each logical qubut. Since Y = ZX and the Pauli matrices are a basis, this code is able to correct all errors. Quantum error correction is remarkable in that an entire continuum of errors ...

... schemes we choose square pulses with Rabi frequency j and duraction j = / j. This leads to an excitation probability P(q) shown right. With increasing pulse duraction the region of excitation is narrowed down. All momenta q except those with q¼0 are excited. By using Blackman pulses a more box ...

... For one, the state |ψi of a system is not an observable. Given a quantum system, there is no way to tell in what state |ψi it was prepared. If the state |ψi is known, the state can be “copied” by preparing another system. But it is impossible to copy an unknown quantum state. This means that many te ...
