具有量子输入或输出的量子非局域游戏已以多种不同形式被构建，包括秩一游戏、量子异或游戏、投影格之间的支撑映射、概率量子超图以及有限量子集上的弗罗贝尼乌斯代数规则算子。我们通过为每个规则分配其获胜变换空间（即被确定性接受的变换的算子空间），对这些模型进行了统一的算子代数比较。我们引入了具有有限维输入和输出冯·诺依曼代数以及任意（可能无限维）裁判冯·诺依曼代数\\\\(\mathcal{R}\\\\)的\\\\(\mathcal{R}\\\\)-投影测试量子游戏。它们的获胜变换空间恰好是具有自然双模结构的算子空间，等价于矩形量子关系。我们将该形式体系与投影格游戏、超图量子游戏以及图形规则算子定义进行比较：投影格游戏恰好捕获自反获胜双模；超图量子游戏具有保价值的投影测试实现，且在过渡到完美变换后，其描述的自反部分与投影格游戏相同。利用道斯（Daws）的技术，我们还将规则算子转化为有限维冯·诺依曼代数张量积中的投影，该识别将图形规则置于同一算子双模框架中，同时保留了价值与完美性。最后，我们将并发与戈德堡（Goldberg）以及博赫尼亚克-卡斯普扎克-索尔特（Bochniak-Kasprzak-Sołtan）的同步条件进行比较。该框架通过经典、秩一、量子异或、着色以及量子图同态与同构游戏得到说明。
英文摘要
Quantum non-local games with quantum inputs or outputs have been formulated in several different languages, including rank-one and quantum XOR games, support maps between projection lattices, probabilistic quantum hypergraphs, and Frobenius-algebraic rule operators on finite quantum sets. We give a unified operator-algebraic comparison of these models by assigning to each rule its winning transformation space: the operator space of transformations accepted with certainty. We introduce \(\mathcal R\)-projection-test quantum games with finite-dimensional input and output von Neumann algebras and an arbitrary, possibly infinite-dimensional, referee von Neumann algebra \(\mathcal R\). Their winning transformation spaces are precisely operator spaces with a natural bimodule structure, equivalently rectangular quantum relations. We compare this formalism with projection-lattice games, hypergraph quantum games, and the graphical rule-operator definition. Projection-lattice games capture exactly the reflexive winning bimodules. Hypergraph quantum games admit value-preserving projection-test realisations, and, after passing to perfect transformations, describe the same reflexive part as projection-lattice games. Using Daws' technique, we also translate rule operators to projections in tensor products of finite-dimensional von Neumann algebras. This identification places graphical rules in the same operator-bimodule framework and preserves both values and perfectness. Finally, we compare concurrency with the synchronicity conditions of Goldberg and of Bochniak--Kasprzak--Sołtan. The framework is illustrated by classical, rank-one, quantum XOR, colouring, and quantum graph homomorphism and isomorphism games.
