[42] demonstrated cascaded quantum time transfer over 2×100 km using relay stations that generatefreshentangled photon pairs at each hop, achieving 3.82 ps TDEV at 10 s and 0.39 ps at 5,120 s. This approach preserves the broadband correlations on each segment but requires each relay node to be physically secured (a trusted-node architecture). No multi-segment quantum repeater chain has been demonstrated to date for any application, and"},{"citing_arxiv_id":"2604.19802","ref_index":21,"ref_count":1,"confidence":0.5,"is_internal_anchor":false,"paper_title":"Electric field dependent g factors of RaOCH$_3$ molecule","primary_cat":"physics.atom-ph","submitted_at":"2026-04-11T03:51:53+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":4.0,"formal_verification":"none","one_line_summary":"A new method calculates electric-field-dependent g-factors for the first excited rotational level of RaOCH3 and identifies K-doublet levels with small g-factor differences.","context_count":0,"top_context_role":null,"top_context_polarity":null,"context_text":null},{"citing_arxiv_id":"2604.08692","ref_index":81,"ref_count":1,"confidence":0.5,"is_internal_anchor":false,"paper_title":"Arqon: A suite of control applications enabling a reliable quantum network","primary_cat":"quant-ph","submitted_at":"2026-04-09T18:25:44+00:00","verdict":"UNVERDICTED","verdict_confidence":"LOW","novelty_score":5.0,"formal_verification":"none","one_line_summary":"Arqon delivers reliable quantum network service via admission control and scheduling that satisfies defined reliability requirements for accepted demands in static topologies, with O(k^3) and O(N^3) complexity.","context_count":1,"top_context_role":"background","top_context_polarity":"background","context_text":"Englund, and R.
