量子反閘是量子版的反閘,是量子計算中量子線路的一種邏輯閘,與古典反閘功能雷同,在於使量子位元的狀態從
、
。
其數學形式為:
![{\displaystyle \mathrm {NOT} |0\rangle =|1\rangle }](https://wikimedia.org/api/rest_v1/media/math/render/svg/64ead810e51c1b99a13f460d5b0fcf878ba46fec)
![{\displaystyle \mathrm {NOT} |1\rangle =|0\rangle }](https://wikimedia.org/api/rest_v1/media/math/render/svg/3f442ec023de294518f43320b8e2547eb5f3d981)
若寫成矩陣形式即為泡利X矩陣:
![{\displaystyle \sigma _{x}={\begin{pmatrix}0&1\\1&0\end{pmatrix))}](https://wikimedia.org/api/rest_v1/media/math/render/svg/799d02ca7ed8e2ebc396f2007aa4bf3b77c259da)
