Quantum mechanics poses several challenges in ontological elucidation. Contextuality threatens determinism and favors realism about possibilia. Indistinguishability challenges traditional identity criteria associated with individual objects. Entanglement favors holistic and relational approaches. These issues, in close connection with different interpretations of quantum mechanics, have given rise to various proposals for the ontology of quantum mechanics. There is a proposal that is realistic about possibilia, where quantum systems are seen as bundles of possible intrinsic properties. This proposal is developed in close connection with modal interpretations and addresses quantum contextuality straightforwardly. There are also proposals based on relations, associated with the relational quantum mechanics interpretation. In this paper, features of these proposals are combined to obtain a modal bundle-theorist relational proposal. Its aim is to consistently and straightforwardly address both contextuality and the holistic and relational aspects of quantum mechanics arising from quantum entanglement. The proposal, if some additional principles are assumed, may turn out to be both an instance of moderate structuralism and priority monism.

量子力学在本体论阐明方面提出了一些挑战。情境性威胁着决定论，并支持关于可能性的现实主义。不可区分性挑战了与单个物体相关的传统身份标准。纠缠有利于整体和关系方法。这些问题与量子力学的不同解释密切相关，引发了对量子力学本体论的各种提议。有一个关于可能性的现实建议，其中量子系统被视为可能的内在属性的集合。该提案的制定与模态解释密切相关，并直接解决了量子上下文问题。还有一些基于关系的建议，与关系量子力学解释相关。在本文中，这些建议的特征被结合起来以获得模态束理论家关系建议。其目标是一致、直接地解决量子纠缠引起的量子力学的背景性和整体性和关系性方面。如果假设一些额外的原则，该提案可能会成为温和结构主义和优先一元论的实例。
