Alternatively, deferring all measurements until the end of circuits allows them to be analyzed using only [[pure state]]s. |

In error corrected code blocks, the instruction set is limited to some discrete set.{{cite book |author=Williams |first=Colin P. |title=Explorations in Quantum Computing |publisher=[[Springer Science+Business Media|Springer]] |year=2011 |isbn=978-1-84628-887-6}} This error corrected instruction set almost always include the [[Pauli matrices|Pauli gates]]. One way to extend the error corrected instruction set of a quantum computer is to exploit the principle of deferred measurement, to convert [[Quantum logic gate#Controlled_gates|quantum controlled]] Pauli gates that are typically not in the error corrected set of quantum gates, into [[Quantum logic gate#Classical_control|classically controlled]] Pauli gates.{{Cite journal | arxiv = quant-ph/9908010 |last1= Gottesman|first1=Daniel |last2=Chuang | first2=Isaac L.|title = Quantum Teleportation is a Universal Computational Primitive|year = 1999 |journal=[[Nature (journal)|Nature]] |volume=402 |issue= 6760|pages=390–393 |doi=10.1038/46503|bibcode= 1999Natur.402..390G|s2cid= 4411647}} |
