The Quantum Circuit Model and Universal Quantum Computation
... So far we have talked about quantum computations involving only a few qubits. In this lecture I’d like to begin to discuss how we might scale this up to more than a few qubits and to make something resembling a valid model of computation. To do proper justice to this task, we should probably review ...

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 ...

A Gentle Introduction to Quantum Computing
... obeys time symmetery. A quantum mechanical system that is evolved from a given initial state to a final state using a definite series of operations can be evolved backwards from the final state to the initial state using the inverse of the series of operations on it. A quantum computer is also a rev ...
