ICTK Co., Ltd., a South Korean quantum‑security fabless firm, and Jiran Security, a cybersecurity specialist, signed a memorandum of understanding to launch Q‑BRIDGE, a commercial service that delivers end‑to‑end post‑quantum cryptography (PQC) migration for enterprises, government agencies and financial institutions. The partnership combines Jiran’s Crypto Discovery platform, which audits cryptographic assets, identifies vulnerabilities and creates migration roadmaps, with ICTK’s hardware‑rooted security architecture built on its VIA PUF™ hardware root‑of‑trust chips. Jiran will conduct initial diagnostics for more [...]

Applied quantum‑technology firm EigenQ, Inc. and SPAC Silicon Valley Acquisition Corp. (SVAQ) have signed a securities purchase agreement for $45 million in convertible notes, arranged by Cohen & Company Securities. The financing provides $22.5 million upfront, with an additional $22.5 million payable upon completion of their previously announced $3 billion enterprise‑value merger. The combined entity is slated to list on the Nasdaq Global Market under the ticker EIGQ in Q4 2026. EigenQ will use the proceeds to speed commercial rollout of its [...]

Stanford physicists recorded the first real‑time quantum jumps of sound by monitoring individual phonons in a microscopic mechanical resonator coupled to a superconducting qubit. The resonator, fabricated with chip‑making techniques, vibrated for two milliseconds, allowing repeated measurements that captured discrete energy transitions from one phonon state to zero. The experiment demonstrates quantum behavior in sound, a prerequisite for quantum computing error correction and ultra‑sensitive sensing, such as protein detection in cells. The findings were published in Science. [...]

USC researchers and Quantum Elements demonstrated subthreshold surface‑code scaling on IBM’s 156‑qubit Heron heavy‑hex superconducting QPUs, publishing results in Nature Communications. The team engineered a depth‑minimizing “fold‑unfold” SWAP embedding with bridge ancillas and applied robust dynamical decoupling to suppress idle‑time noise and coherent ZZ crosstalk. Scaling was achieved from distance d = 3 (37 qubits) to anisotropic (3,5) and (5,3) configurations (65 qubits), confirming that non‑native honeycomb lattices can support distance‑scaling error suppression. The study also introduced an SPAM‑aware entanglement [...]

Q‑SAFE Solutions GmbH announced a carrier‑grade quantum‑safe network platform built entirely within the EU‑27, targeting telecom operators, critical‑infrastructure owners and government agencies. The system fuses Quantum Key Distribution (QKD) with Post‑Quantum Cryptography (PQC) in a hybrid key‑agreement scheme, using physics‑derived entropy together with standardized key‑encapsulation mechanisms. Keys are delivered over existing lit fiber alongside regular traffic via ETSI GS QKD 004 and 014 interfaces, eliminating the need for dedicated dark‑fiber links. The architecture supports point‑to‑point, star and trusted‑relay [...]

Oxford Quantum Circuits (OQC) has launched Erado, an open‑source Python library that adds a 16‑qubit AerSimulator backend to its Quantum Computing as a Service (QCaaS) SDK. Erado models erasure noise, dual‑rail qubit encodings and post‑selection on arbitrary Qiskit circuits, letting developers benchmark erasure‑aware noise models and test error‑mitigation strategies before running on hardware. The tool offers configurable parameters such as per‑gate erasure probability, false‑positive and false‑negative detector rates, and idle‑error padding, with two execution modes: exact state‑vector [...]

The Quantum Insider (TQI) has announced a partnership with Swiss non‑profit Tesseract Quantum, the creator of the YouTube channel The Quantum Kid. Launched in June 2025, the channel—run by physicist Katia Moskvitch and her 10‑year‑old son Kai—has amassed over 120,000 subscribers and nearly 3 million views, featuring interviews with Nobel laureates and quantum pioneers. The collaboration will combine TQI’s industry access with the channel’s “explain it to me like I’m 10” style to broaden outreach on quantum research [...]

Oxford Quantum Circuits (OQC) partnered with Trust Base, the digital‑innovation arm of Sumitomo Mitsui Trust Group, to benchmark classical, hybrid quantum‑classical and fault‑tolerant quantum algorithms on core financial risk‑modeling tasks. The study compared four architectures—classical Monte Carlo, classical physics‑informed neural networks (PINNs), quantum‑compressed PINNs (QPINNs) and quantum Monte Carlo (QMC) via amplitude estimation—across Black‑Scholes/Garman‑Kohlhagen, Dupire local‑volatility and Hull‑White models. QPINNs showed higher parameter efficiency but suffered from latency and noise‑sensitive Gamma calculations, while classical PINNs delivered faster runtimes and greater [...]
