To perform practical fault\u2010tolerant quantum computations, however, not only do we require precision manufacturing techniques to produce millions of qubits, but these techniques need to consistently yield low\u2010error qubits. A deep understanding and control of the interactions between the qubits and their environment are needed as we scale so that devices can be engineered to avoid high error rates. In this work, we experimentally and theoretically characterize two often\u2010overlooked error mechanisms affecting nuclear spin qubits in silicon caused by local interactions. The first is the direct magnetic interactions between nuclear spins, causing dipolar coupling errors, and the second is the interactions between the nuclear spins and their associated electron spin, causing \u201chotspots\u201d of anisotropic hyperfine coupling errors. By modeling the properties of the combined electron\u2013nuclear spin system as a function of magnetic field, contact hyperfine strength, and electron tunnel rate, we show how these errors can be reliably mitigated, giving rise to readout fidelities of .<\/jats:p>","DOI":"10.1002\/advs.77080","type":"journal-article","created":{"date-parts":[[2026,9,27]],"date-time":"2026-09-27T18:00:31Z","timestamp":1790532031000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Dipolar Coupling Errors in Nuclear Spin Qubits"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-0761-2738","authenticated-orcid":false,"given":"I.
