Quantum Computing Weekly Round-Up: Week Ending September 5, 2026

Quantum Computing Weekly Round-Up opens September with a Riyadh research pact, a Canadian soup plant turned photonics factory, a 120-qubit processor that slings more than 100,000 circuits a second, and a silicon machine booking an Equinix cage in Sydney. Pasqal signed with KACST. Xanadu locked CAD $195 million. IBM pushed Nighthawk r2. Skip a single link and you will spend Monday pretending you already knew the Gulf, Canada, and a Sydney data hall all moved at once.Pasqal did not treat the Nasdaq ticker as a victory lap. On August 31 the company signed a multi-year research pact with King Abdulaziz City for Science and Technology, represented by the National Center for Quantum Technologies. The Pasqal KACST pact pairs neutral-atom processors and cloud services with KACST labs, starting on quantum-safe cryptography for government, finance, and critical infrastructure. The ceremony landed at King Salman Science Oasis during a World Quantum Day event.The same week Arab News mapped a quantum-enabled economy under Vision 2030, with a National Quantum Strategy, a foundry, and sandboxes at Aramco and NEOM on the punch list. Quantinuum signed a non-binding Aramco MOU to hunt energy and digital-transformation use cases and to benchmark modalities. That is not a purchase order. It is a country treating quantum as industrial policy.Saudi telecom Salam added two Huawei agreements at LEAP 2026 covering next-generation IP networks and a QKD feasibility track. If you still think the Kingdom is window shopping, you have not been reading.Canada wrote the loudest manufacturing check. Ottawa put CAD $195 million from the Strategic Response Fund behind Xanadu’s Project OPTIMISM and the Inception photonics plant, a 158,000-square-foot Etobicoke build with cleanrooms, heterogeneous integration, and a systems centre meant to feed fault-tolerant photonic hardware. Christian Weedbrook called it a defining milestone. The empty Campbell’s footprint is now a factory floor.Across the Atlantic, the Novo Nordisk Foundation and Quantum Foundry Copenhagen announced a Copenhagen chip facility of 5,300 square meters, due in 2027, to sell wafer fabrication rather than another prototype fridge. Bloomberg tagged the build at about $62 million. The Foundation has already committed more than DKK 2.9 billion to quantum.Quantum Motion closed a second slice of its Series C. The additional silicon investment brings Imec.ventures, Lansdowne Partners, Sony Innovation Fund, S3 Ventures, and Inkef onto a $160 million round led by DCVC and Kembara. The incremental number stayed private. The Maryland lab and the DARPA QBI Stage B seat did not. Finland’s S-Transistors raised €2.6 million seed from Lifeline Ventures for cryogenic superconducting transistors and a pilot line. Money is following plants, transistors, and test racks.Diraq is putting an eight-qubit silicon machine inside an Equinix Sydney hall, self-contained cryogenics and all, drawing less than 20 kW, with installation aimed at October 2026. Andrew Dzurak’s pitch is the unromantic one: the advantage is that it racks like anything else.IBM published Nighthawk r2 specs: 120 programmable qubits, mid-circuit reset, and more than 100,000 circuits per second, about 25 times Heron throughput. The company says the chip holds accuracy on circuits with 7,500-plus gates. In Seoul, IBM’s Baek Han-hee told Sedaily the 2029 boom starts when Starling arrives and the argument shifts from qubit counts to software that bills.QTREX, trading as QTEX, will show an interconnect architecture for 17,280 cryogenic lines per stage at IEEE Quantum Week in Toronto. Wiring is the unglamorous bottleneck. This week someone tried to print their way out of it.Quobly and TNO signed an MOU on spin qubits to industrialize 300 mm FD-SOI devices with high-throughput metrology. OrangeQS extended its MAX platform into spin-qubit testing with Equal1 and Quobly. The test-equipment vendors are following the CMOS crowd.At SEMICON Taiwan, SEEQC signed an MOU with Taiwan’s Quantum Industry Technology Promotion Office for manufacturing, test, and supply-chain work. Classiq added Scientek and Kensho as local go-to-market partners. Commonwealth Magazine sketched Taiwan’s Big Six quantum bets, from Hon Hai’s trapped-ion lab to Quanta’s NT$3 billion spread across Rigetti, Quantinuum, and Pasqal. The island that built the AI server is shopping for the next rack.Rep. Nick Langworthy introduced the American Competitiveness Act, putting Commerce on the hook for a trusted quantum supply chain and a public report every three years. It is a bill, not a budget.Europe still trains. China still hires.

The Qubit Report tracked Guo Yanliang’s move from Innsbruck to an associate professorship at Renmin University, another ultracold-atom PI who learned the craft in EU labs. EE Times argued India’s quantum journey is already bigger than a qubit target, with a ₹6,003.65 crore National Quantum Mission, a 1,000-km QKD network from QNu Labs, and QpiAI stacking named processors toward a 2029 logical-qubit goal.Arqit, Es’hailSat, and AIEE ran quantum-safe satellite security across Es’hail-1 and the Doha teleport with no service hit. Sparkle and Hellas Sat stood up a Greece-Cyprus satellite link using a post-quantum IPsec overlay on a 72,000-kilometer geostationary path. QuSecure took QuProtect to TRL-7 at the U.S. Army’s Project Convergence Capstone 6.ESA said the QKDSat pulse source from DAS Photonics is qualification-ready for Honeywell’s Partnership Project. SEALSQ added wolfTPM support so QVault’s ML-DSA and ML-KEM can talk to the firmware everyone already ships. The overlay is no longer a conference slide. It is flying, marching, and compiling.QC Ware and IonQ put Promethium on Forte and modeled a heme active site within 0.5 kcal per mol of classical benchmarks, inside the chemical-accuracy line. Pasqal and True Nexus said they encoded protein structures tied to gelation on neutral-atom hardware. That is a milestone, not a product SKU.Fidelity Digital Assets mapped Bitcoin resistance options, including hash-based designs such as SHRINCS and the social-consensus tax of a soft fork. CryptoSlate warned USDC is only as quantum-safe as its slowest wallet, bridge, or chain across 37 networks. Circle can rotate its own keys. It cannot rotate yours. The Street packaged Elon’s nine-word Planck reply (“The universe is integer in units of Planck cubes”) as a take on the quantum race. He was answering a physics thread, not blessing your seed phrase.Hong Kong Polytechnic University published a tunnelling field-effect transistor in Science that beat the 60 mV/decade Boltzmann wall at room temperature on centimetre-scale silicon. MIT unveiled an Arm qubit architecture that splits storage from interaction to cut errors. Osaka, NICT, and Hamamatsu showed a 10-channel photonic interface for neutral-atom arrays in Optica, a record for that class of link.Origin Quantum, USTC, and Hefei partners measured coherent bucket-brigade QRAM routers on the third-generation Wukong chip, with 98 percent router transmission on a 10-qubit slice of a 72-transmon processor. It is not a full QRAM. It is a router that finally looks like one.This week the Quantum Computing Weekly Round-Up watched factories get funded, racks get reserved, satellites get post-quantum overlays, and Riyadh treat quantum as an economic plan, which is why skipping the links is how you fall a week behind.—See the full week of articles in the Weekly Archives Pages and the Weekly Round-Ups found at The Qubit Report.Origin Wukong tests show up to 98% single-router transmission for QRAM on the 72-qubit third-generation chip. Physical Review X reports a two-layer network at 93% Sparkle and Hellas Sat have run a live quantum-safe satellite connection on a 72,000 kilometer geostationary hop between Greece and Cyprus. The trial extends Sparkle Classiq signed a Scientek go-to-market agreement and a separate Kensho market-development partnership to expand Classiq quantum software in Taiwan.
