Recently, Che and Wu (2019 Int. J. Theor. Phys. 58 584–90) presented a recurrence relation of multi-qubit states. Inspired by this, we present the recurrence relation of ququart maximally entangled states. Further, via the recurrence relation of six ququarts maximally entangled states, a seven ququarts absolutely maximally entangled state can be constructed. We also show this state is the three-uniform state of seven ququarts states.

通过递归关系构造七个绝对最大纠缠态的四方

近日，车和吴（2019诠释。J.理论值的PHY。 58 584-90）提出的多量子位状态的递推关系。受此启发，我们提出了Ququart最大纠缠态的递推关系。此外，通过六个最大夸脱态的四方的递归关系，可以构成七个最大最大纠缠态的四方。我们还显示了该状态是七个Ququarts状态的三一致状态。
