Welcome to the Quantum News Daily Brief. Story 1: NLM Photonics and LIGENTEC Build First Silicon Nitride Organic Hybrid Modulators Amid Materials Supply Chain Expansion. NLM Photonics and LIGENTEC Build First Silicon Nitride Organic Hybrid Modulators Amid Materials Supply Chain Expansion Electro-optic materials developer NLM Photonics, Swiss photonic integrated circuit (PIC) foundry LIGENTEC SA, and design firm Spark Photonics have fabricated the first Silicon Nitride Organic Hybrid (NOH) modula

Welcome to the Quantum News Daily Brief. Story 1: AlchemQ: Proof-Carrying Quantum Circuit Optimization with Per-Result Equivalence Certificates. Certificates are self-contained and tamper-evident: canonical gate-canon-v1 hashes, measured residuals, tri-state verdicts (certified/rejected/inconclusive), and versioned phase-note schemas for cross-platform reproducibility. The agent aggregates three fuzzy t-norms, cannot return an uncertified circuit, and since v0.4 guarantees no componentwise regre

Welcome to the Quantum News Daily Brief. Story 1: Neutral Atom continues to shine in the modality race. The second paper linked discusses how the researchers were able to achieve a fidelity improvement of 5.3x by optimising atom loss in neutral-atom quantum error correction systems. There has been recent developments around neutral atom in the past 3 months. A lot of folks think software will always be the most profound obstacle holding quantum back but I think AI will help ease some of the algo
