Fault-Tolerant Quantum Computation and the Threshold Theorem
... In any discussion of the threshold theorem for fault-tolerant quantum computation, one of the most important points is what is assumed in the order to produce the threshold. It is useful to list the assumptions which are put into the model. We will not be able to discuss the threshold theorem under ...

... One can also look at CNOT as a gate with one input qubit (controller) and one output qubit (controlled). CNOT flips the state with respect to its output wherever its input is 1. By making the condition on this flipping more complex, possibly using more input qubits, we can construct analogous unita ...
