Image courtesy Quip.Network.In this quantum computing weekly round-up, the pace is relentless—funding is pouring in, hardware is getting real-world ready, and the post-quantum security conversation just got a whole lot more urgent. If you skipped any of these stories, you’re going to want to click through now before the next big move drops and leaves you playing catch-up.The cash registers were ringing loud and clear. Finnish quantum unicorn IQM secured €50 million from BlackRock ahead of its public listing push, according to EU-Startups. Monarch Quantum surpassed $100 million in total capital and contracts after closing a $55 million growth round to scale its photonics infrastructure. Alice & Bob landed a $3.9 million ARPA-E award to put quantum computing to work designing rare-earth-free magnets. BTQ Technologies and Infleqtion also dropped full-year 2025 updates showing real commercial traction across multiple fronts.Engineers are delivering the goods that actually move the needle. Quantum Motion demonstrated a new high-performance qubit readout method that’s fast, scalable, and ready for spin-qubit arrays. UCSB researchers unveiled integrated stabilized laser chips that double as precision clocks and quantum controllers. NIST rolled out photonic chip packaging built to survive extreme conditions, while Harvard showed off racetrack-shaped lasers pumping out bright, stable frequency combs. QuEra launched an open-source package that simulates logical quantum circuits at massive scale on GPUs.The security crowd is wide awake. HP introduced a fresh LaserJet portfolio with built-in quantum-resistant security. Google warned of five quantum attack paths that could put $100 billion on Ethereum at risk, as reported by CoinDesk, while Ars Technica detailed how new advances are heightening the threat to elliptic-curve cryptosystems. SEALSQ and Kaynes Semicon inaugurated India’s first post-quantum cryptography personalization center, PQShield teamed with Japan’s CRYPTREC on PQC scale-up, and Naoris Protocol deployed its post-quantum mainnet.Orbit is the new lab bench. QuantX Labs launched the world’s first optical atomic clock technology into space. WISeKey’s WISE-SAT subsidiary sent its 21st satellite to low-Earth orbit aboard SpaceX, and Infleqtion delivered quantum precision timing for mission-critical systems.The labs keep dropping gems. LMU debuted a highly sensitive quantum microscope that twists light into sharper focus. FSU researchers clarified quantum magnetism in atomic nuclei, three fresh arXiv preprints pushed theoretical boundaries, and The Qubit Report unpacked the hidden thread connecting heat, information, and quantum computers.Governments are all-in. Canada announced new support for quantum computing in Saskatchewan, South Africa secured a national quantum technology hub at the University of Pretoria, and the DOE partnered on a quantum algorithm competition to strengthen the grid plus a $320 million nuclear-quantum research push. Stony Brook advanced national quantum leadership on Capitol Hill.Real products are rolling. QCI placed its quantum optimization machine on the Quantum Corridor network, LQUOM and Toshiba signed a joint research deal on long-distance QKD repeaters, and STV Group ran the first post-quantum trial of quantum-resilient drones Down Under.This week proved quantum tech is no longer “someday”—it’s shipping, funding, orbiting, and forcing every CISO and policymaker to update their playbooks right now.—See the full week of articles in the Weekly Archives Pages and the Weekly Round-Ups found at The Qubit Report.This Quantum Computing Weekly Round-Up highlights a busy week where governments and companies ramped up efforts in quantum security, navigation, and computing power.
