连续变量四模无权图态的局部互补规则
Local complementation rule for continuous-variable four-mode unweighted graph states
摘要:
本文将局部互补规则应用于连续变量(CV)图的状态,这是一种基本的图变换规则,连续应用该规则可生成任意图状态的轨道。对于四模无权图态,发现了相应的局域补高斯变换,但它们并不完全反映量子比特的局域Clifford幺正形式。这是刻画CV图状态局部高斯等价类的重要一步。
英文摘要:
The local complementation rule is applied for continuous-variable (CV) graph states in the paper, which is an elementary graph transformation rule and successive application of which generates the orbit of any graph states. The corresponding local Gaussian transformations of local complementation for four-mode unweighted graph states were found, which do not mirror the form of the local Clifford unitary of qubit exactly. This work is an important step to characterize the local Gaussian equivalence classes of CV graph states.
