The answer is negative: Letting A be a real hermitian matrix which is larger than J S01 , that is, A > J S01, there exists such an unbiased estimator M that V [M ] is not smaller than A. In other words, there is no better bound than SLD CR bound. In the general case, therefore, no ...

Fault-Tolerant Quantum Computation and the Threshold Theorem
... Before discussing how to perform fault-tolerant operations, it is nice to see where all of our discussion is heading. Suppose that we have constructed a fault-tolerant set of operations (gates, preparation, measurement, error correction) for a quantum error correcting code. In such a construction, i ...
