Motional Quantum Error Correction
Is it possible to preserve quantum coherence in systems that are irreversibly coupled to the environment? Apart from being of fundamental interest, this question is of particular significance in the area of quantum information processing [1], where the first two-bit quantum gate operations have been demonstrated in quantum optical systems such as trapped ions [2], and optical cavities [3]. In t...
متن کاملQuantum Error-Correction Codes on Abelian Groups
We prove a general form of bit flip formula for the quantum Fourier transform on finite abelian groups and use it to encode some general CSS codes on these groups.
متن کاملQuantum Error Correction
⋆ It seems very unlikely that quantum computation can be realized unless there is some means of correcting the errors which will inevitably arise when physical devices are constructed to carry out such a computation. The situation is far different from that in ordinary “classical” computers in which for most purposes the probabilities of errors are so small that they can be ignored. • The absen...
متن کاملExperimental Quantum Error Correction
Quantum error correction is required to compensate for the fragility of the state of a quantum computer. We report the first experimental implementations of quantum error correction and confirm the expected state stabilization. In NMR computing, however, a net improvement in the signal-to-noise would require very high polarization. The experiment implemented the 3-bit code for phase errors in l...
متن کاملQuantum error correction
Suppose for simplicity that our system consists of a single qubit. We start with errors we are familiar with from the classical setting – bit-flips. Such an error converts the original state, say α|0〉+β |1〉, into α|1〉+β |0〉. We can correct these kind of errors using classical error correcting codes. For example, we may use a repetition code, i.e., encoding |0〉 as |000〉 and |1〉 as |111〉. Thus, w...
