In this context, the visualisation of sets of multi-qubit pure quantum states on a single image can be helpful. However, the current approaches to visualization of this type only allow the representation of a set of single qubits (not allowing multi-qubit systems) or a just a single multi-qubit system (not suitable if we care about sets of states), sometimes with additional restrictions, on symmetry o","authors_text":"Alice Barthe, Jordi Tura, Michele Grossi, Vedran Dunjko","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2023-02-06T17:39:19Z","title":"Bloch Sphere Binary Trees: A method for the visualization of sets of multi-qubit systems pure states"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2302.02957","kind":"arxiv","version":1},"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:fee4effc85215472f0f5217073d21881e1f8aa3e9bfa26f567f50a280ace00a0","target":"record","created_at":"2026-07-05T05:39:08Z","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":"d87a872d2b1c07a640106619811ad58fec096b68d885f16af211d4d6f4687143","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2023-02-06T17:39:19Z","title_canon_sha256":"e1dfc1692436ff2c74edf45f4d09e8e33fd9225a9045d0fb11afba3b4eb667c0"},"schema_version":"1.0","source":{"id":"2302.02957","kind":"arxiv","version":1}},"canonical_sha256":"d688ec48c9a7f34746921d790565a40d05694711b93b99b718d4afd0af5159f2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d688ec48c9a7f34746921d790565a40d05694711b93b99b718d4afd0af5159f2","first_computed_at":"2026-07-05T05:39:08.504653Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:39:08.504653Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VJvCQ1SStnW3S+JVTpUEcYFbSmJ0xuDP9jEkPcCPM+HZXmVhaatr4VASQ6Px4klvnYDHGgXdQKNuB8RXys6yBg==","signature_status":"signed_v1","signed_at":"2026-07-05T05:39:08.505251Z","signed_message":"canonical_sha256_bytes"},"source_id":"2302.02957","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:fee4effc85215472f0f5217073d21881e1f8aa3e9bfa26f567f50a280ace00a0","sha256:ac1cb5a1f9ea96efd5260867a42dd07c6b02675ec413ac965599927ab8cdb15f"],"state_sha256":"e85d1c182845fee04717926686e12bf21d1beabd79ba68e1cd456d12275df22a"}
