The basic idea of our method is to learn a unitary operation $\\hat{U}$ that transforms a given unknown state $|\\psi_\\tau\\rangle$ to a known fiducial state $|f\\rangle$. Then, after completion of the learning process, we can estimate and reproduce $|\\psi_\\tau\\rangle$ based on the learned $\\hat{U}$ and $|f\\rangle$. To realize this idea, we cast a random-based learning algorithm, called `single-shot measurement learning,' in which the learning rule is based on an intuitive and reasonable criterion: the greater the number of s"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1805.06580","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
