Line 73:
Once a cluster state has been successfully generated, computation can be done with the resource state directly by applying measurements to the qubits on the lattice. This is the model of [[one-way quantum computer|measurement-based quantum computation]] (MQC), and it is equivalent to the [[quantum circuit|circuit model]].
Logical operations in MQC come about from the byproduct operators that occur during [[quantum teleportation]]. For example, given a single qubit state <math>|\psi\rangle</math>, one can connect this qubit to a plus state (<math>|+\rangle=|0\rangle+|1\rangle</math>) via a two-qubit controlled-Z operation. Then, upon measuring the first qubit (the original <math>|\psi\rangle</math>) in the Pauli-X basis, the original state of the first qubit is teleported to the second qubit with a measurement outcome dependent extra rotation, which one can see from the partial inner product of the measurement acting on the two-qubit state:
