Quantum computation, non-demolition measurements, and reflective
... the state of quantum computer for error correction has the effect of making its operating states macroscopically indistinguishable: the more “stable” the code is, the more errors it can correct in each pass. The concatenated codes involve re-encoding already encoded bits. This process reduces the ef ...

In Fig. 2(f) we report the histogram of the occurrence of different values of probabilities, that quantify the nonorthogonality component of the experimental projectors. We observe a good agreement with the null value expected for orthogonal ...

Operator methods in quantum mechanics
... This is clearly a discrete transformation. Application of parity twice returns the initial state implying that P̂ 2 = 1. Therefore, the eigenvalues of the parity operation (if such exist) are ±1. A wavefunction will have a defined parity if and only if it is an even or odd function. For example, for ...
