Labs kept shrinking the photonics stack and turning microwave noise into entanglement, while governments treated GPS denial and post-quantum migration as operational work. Europe still published more than it commercialized. Japan’s NEC left the hardware race. Makes ya’wonder!?
Quantum Computing Weekly Round-Up for the week ending September 5, 2026 tracks factories, racks, and post-quantum links moving at the same time. Pasqal signed a multi-year quantum-safe research pact with KACST in Riyadh. Canada put CAD $195 million behind Xanadu’s Inception photonics plant. IBM published Nighthawk r2 at 120 qubits and more than 100,000 circuits per second. Diraq reserved an Equinix cage in Sydney. Quantum-safe overlays flew on Es’hail-1 and a Greece-Cyprus satellite path.
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% transmission and 82.4% random-access fidelity, two different metrics. Partner names, TCG method, and the Tian Feng caution sit in the full report.
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 Quantum Safe Interconnect, a software post-quantum overlay on IPsec, after a March ground PoC announcement. Quotes and the commercial evaluation plan sit in the full report.
Classiq signed a Scientek go-to-market agreement and a separate Kensho market-development partnership to expand Classiq quantum software in Taiwan. Scientek will work semiconductor, research, university and government accounts; Kensho will handle introductions, local support and training, with an early focus on chemical, materials and defense buyers. SEMICON Taiwan 2026 booths, executive remarks and the Q2T follow-on context appear in the full report.
Fidelity Digital Assets published a September 1, 2026 research note on Bitcoin quantum resistance, written by Daniel Gray. The note says a future cryptographically relevant quantum computer could threaten ECDSA and Schnorr private-key control once public keys appear on chain. Readers can review the SHRINCS design, signature-size trade-offs, and the soft-fork path Fidelity outlines for holders and custodians.
U.S. Representative Nick Langworthy introduced the American Quantum Competitiveness Act on August 31, 2026, making the Secretary of Commerce principal advisor to the President on commercial quantum technology and trusted supply chains. A public competitiveness strategy would be due within two years of enactment and every three years after. Full statutory duties, corridor geography, and industry quotations are in the article.
Arqit, Es’hailSat and AIEE Demonstrate Quantum-Safe Satellite Security Key Takeaways Live Network Test: Arqit, Es’hailSat, and AIEE applied quantum-safe encryption across live satellite-connected networks using
Quantum Computing Weekly Round-Up for the week ending August 29, 2026 captures the week quantum computing became a public-market and public-policy story at the same time. Pasqal listed on Nasdaq with €309 million in cash. IBM closed its HRL Laboratories acquisition. NSF put $290 million behind eight Quantum Leap institutes, and Treasury stood up a financial-sector Quantum-Readiness Task Force. Field trials from Q-CTRL and SuperQ, plus Pasqal’s Saudi joint venture, made the laboratory feel far away.
Infleqtion has received a $20 million NASA follow-on contract for the Quantum Gravity Gradiometer Pathfinder, raising total program investment to $40 million. The JPL-led mission is designed to fly the first space-based quantum gravity sensor, with hardware work through 2027 and a targeted 2030 low-Earth orbit launch. Sensor architecture, microgravity testing plans, and the path to later science-grade instruments are detailed inside.
