However, benchmarking these algorithms at a practical scale has been limited by ineffective simulation methods. We develop a quantum kernel framework using a Matrix Product State (MPS) simulator and employ it to perform a classification task with 165 features and 6400 training data points, well beyond the scale of any prior work. We make use of a circuit ansatz on a linear chain of qubits with increasing interaction distance between qubits. We assess the MPS simulator performance on CPUs","authors_text":"Mekena Metcalf, Nathan Fitzpatrick, Pablo Andr\\'es-Mart\\'inez","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2024-11-14T10:33:07Z","title":"Realizing Quantum Kernel Models at Scale with Matrix Product State Simulation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2411.09336","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":"sha256:4986175fe43354dbc37c87ffe74cd628426b379268083adf3ff0a2c56c1c7217","target":"record","created_at":"2026-07-05T09:35:25Z","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":"c33c3b81ccca778485e7b2fe98902bb74a5f4624a932894875ff1b7927a6ae58","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2024-11-14T10:33:07Z","title_canon_sha256":"ac3edc0eae896a635a407472de0dc91b4e3a4ab867efa5dcfe2acdcdcbfdd815"},"schema_version":"1.0","source":{"id":"2411.09336","kind":"arxiv","version":1}},"canonical_sha256":"3b30c791ff005db3c3f91cb1967ecc1cbff05aea16ccb0d4b3e5d7c284fb56d8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3b30c791ff005db3c3f91cb1967ecc1cbff05aea16ccb0d4b3e5d7c284fb56d8","first_computed_at":"2026-07-05T09:35:25.285063Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:35:25.285063Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"FFpFIAGQabWJcRMRn5Q4kMaoWOxI+MHC5wULl40UWrL2Jbl8NjJS2ayjOsyWgCu9XAcUrhN7/C2AvS0eoljhDA==","signature_status":"signed_v1","signed_at":"2026-07-05T09:35:25.285548Z","signed_message":"canonical_sha256_bytes"},"source_id":"2411.09336","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4986175fe43354dbc37c87ffe74cd628426b379268083adf3ff0a2c56c1c7217","sha256:194943136c066c2bafdbc4821f68b7d7186babd545c0c269850a960d4486719d"],"state_sha256":"933c73a364718c07ef78016ce1efbb8d21f593840330cec158bc5303a606de08"}
