This sequence can conceal the fidelity cost of producing smooth, band-limited, and amplitude-admissible controls. Here, we evaluate a constraint-native alternative based on inexact proximal alternating-direction updates. The formulation combines gate-infidelity minimisation with amplitude bounds, Fourier-domain bandwidth projection, amplitude sparsity, and total-variation regularisation. We compare it with GRAPE, standard Krotov optimisation, and L-BFGS-B on a single-qubit gate, a leakage-p","authors_text":"Ziwen Song","cross_cats":["physics.atom-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2026-03-13T14:27:40Z","title":"Constraint-native quantum control for fidelity--complexity trade-offs with inexact proximal ADMM"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2603.13020","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:0854ae447047d0d76b55ddc47f807fa57ebeb5348c9d2175fe7ae1c658b082b5","target":"record","created_at":"2026-07-14T01:20:01Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"848ebd0ed340552eba01d069ad77699db26b9e575fdf6820d90bc5fb5bba0c53","cross_cats_sorted":["physics.atom-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2026-03-13T14:27:40Z","title_canon_sha256":"3b56cad8a9d152485f911f5b4057edaae9bfd3460e5e3e399b63defdf972ef77"},"schema_version":"1.0","source":{"id":"2603.13020","kind":"arxiv","version":2}},"canonical_sha256":"bfe6cbd7c6d0794c05658961864c48368b86c26cce28aeb1da9c1026de6aa8e1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bfe6cbd7c6d0794c05658961864c48368b86c26cce28aeb1da9c1026de6aa8e1","first_computed_at":"2026-07-14T01:20:01.350095Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-14T01:20:01.350095Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"P+5UuKdaEIU7URDAWDZrlGflufhFKAzRZIHwRA6CGvSpWbMzomfQ2gxaj/mAPRr+p69S04wGWtghCQNDsjUNCQ==","signature_status":"signed_v1","signed_at":"2026-07-14T01:20:01.350954Z","signed_message":"canonical_sha256_bytes"},"source_id":"2603.13020","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0854ae447047d0d76b55ddc47f807fa57ebeb5348c9d2175fe7ae1c658b082b5","sha256:edd5828f684ff9048b539bb7d5e274d4e307449fc6bfab3b83cec6dc19816dff"],"state_sha256":"fa8218e75afc93ce54f2f34ba0b3bcb3faa5b2b210f08587dd088487f12ecf27"}
