摘要

我们描述了产生四量子位最大纠缠态的量子电路，纠缠量通过使用Cayley超行列式的绝对值作为纠缠单调来量化。更精确地说，我们证明了这种类型的四量子位纠缠态可以通过一组$\mathtt{CNOT}$电路作用于状态$|0000\rangle$的LU轨道的一些特殊状态来获得。

Quantum circuits generating four-qubit maximally entangled states

We describe quantum circuits generating four-qubit maximally entangled states, the amount of entanglement being quantified by using the absolute value of the Cayley hyperdeterminant as an entanglement monotone. More precisely we show that this type of four-qubit entangled states can be obtained by the action of a family of $\mathtt{CNOT}$ circuits on some special states of the LU orbit of the state $|0000\rangle$ .

期刊介绍： Mathematical Structures in Computer Science is a journal of theoretical computer science which focuses on the application of ideas from the structural side of mathematics and mathematical logic to computer science. The journal aims to bridge the gap between theoretical contributions and software design, publishing original papers of a high standard and broad surveys with original perspectives in all areas of computing, provided that ideas or results from logic, algebra, geometry, category theory or other areas of logic and mathematics form a basis for the work. The journal welcomes applications to computing based on the use of specific mathematical structures (e.g. topological and order-theoretic structures) as well as on proof-theoretic notions or results.
