Focusing on ($1+1$)-dimensional $\\varphi^4$ scalar field theory, the approach employs the Hamiltonian formalism to map the theory onto a spatial lattice, with fields represented as quantum harmonic oscillators. Using measurement-based quantum computing, we implement non-Gaussian operations for CQVC platforms. The study introduces methods for preparing initial states with specific momenta and simulating their evolution under the $\\varphi^4$ Hamiltonia","authors_text":"Michael Spannowsky, Simon Williams, Steven Abel","cross_cats":["hep-lat","hep-ph","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2025-02-03T19:11:38Z","title":"Real-Time Scattering Processes with Continuous-Variable Quantum Computers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2502.01767","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":"sha256:00b085ef62e0c5bfd67a0d2c86619da4058520049c8e7d70210e4f1b95b65fa1","target":"record","created_at":"2026-07-05T12:03:24Z","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":"275a067d4108f5e23477948850ed42ca49180c9400be3385924c969accc86d36","cross_cats_sorted":["hep-lat","hep-ph","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2025-02-03T19:11:38Z","title_canon_sha256":"7b3393b036380bacda0ea2a5ee2aec1e5895b0f351634ddfd58cca8c3f373b22"},"schema_version":"1.0","source":{"id":"2502.01767","kind":"arxiv","version":2}},"canonical_sha256":"e054b5d37198f89b408282c4af07e79d96486077900f60631ec847ae7afffb57","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e054b5d37198f89b408282c4af07e79d96486077900f60631ec847ae7afffb57","first_computed_at":"2026-07-05T12:03:24.428165Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T12:03:24.428165Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bKfpwWEkBqpWPZEqyyNHYTZUqlJJ3wHNKnteZAh53aPMwpC7kB9YGkuxnQeDWb+0kXJxg6n2LeuSXkmMBbHLAA==","signature_status":"signed_v1","signed_at":"2026-07-05T12:03:24.428687Z","signed_message":"canonical_sha256_bytes"},"source_id":"2502.01767","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:00b085ef62e0c5bfd67a0d2c86619da4058520049c8e7d70210e4f1b95b65fa1","sha256:441cda7e58968ec10f51abb165f9141107ea8a347959135f435dcb4ec20c3072"],"state_sha256":"685f7e0531cfd97e0f97c39ffc9b4f4e41fbc32100dd2b1e80390f05b63b0692"}
