Completed: Yale Facility for Free-Space Quantum Link Across Long Island Sound

Yale University has completed an optical facility in New Haven forming the third facility in a free-space optical quantum link with Stony Brook University and Brookhaven National Laboratory. The demonstrated 13-mile Stony Brook–Brookhaven leg has transmitted quantum states and entangled photons through open air, adding wireless capability to the 161-mile fiber network. Technical details on adaptive optics, the forthcoming 30-mile Q-LATS connection, and SCY-QNet integration show the path toward extended entanglement distribution across Long Island Sound. The post Completed: Yale Facility for Free-Space Quantum Link Across Long Island Sound appeared first on The Qubit Report.

IonQ Subsidiary Skyloom Reaches 84 On-Orbit Optical Terminals Supporting SDA Constellation

IonQ Subsidiary Skyloom Reaches 84 On-Orbit Optical Terminals Supporting SDA Constellation Space-based optical communications developer Skyloom Global—a subsidiary of IonQ (NYSE: IONQ)—has deployed dozens of additional Optical Communication Terminals (OCTs) into low-Earth orbit (LEO). Launched aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base, the optical payloads were integrated onto York Space Systems satellites supporting the U.S. Space Development Agency’s (SDA) Proliferated Warfighter Space Architecture (PWSA).

Interoperable Free-Space Optics: Skyloom’s terminals conform to official SDA optical interoperability standards, enabling direct optical cross-links (OISLs) between orbiting space vehicles and ground stations. Quantum Networking Roadmap: Following IonQ’s acquisition of Skyloom in January 2026, the optical transport layer provides the physical hardware foundation for future distributed quantum entanglement, free-space quantum key distribution (QKD), and space-to-ground quantum interconnects. Led by IonQ President of Quantum Platform Jordan Shapiro, the expansion demonstrates industrial-scale manufacturing and deployment of U.S.-built optical space communications i

Pasqal and Eleven Ventures Form Joint Venture to Scale Neutral-Atom Quantum Systems Across Saudi Arabia and MENA Region

Pasqal and Eleven Ventures Form Joint Venture to Scale Neutral-Atom Quantum Systems Across Saudi Arabia and MENA Region Neutral-atom quantum computing developer Pasqal and Saudi Arabian investment platform Eleven Ventures have signed an agreement to establish a commercial joint venture—Pasqal Arabia—to deploy, commercialize, and scale neutral-atom quantum processors across the Kingdom of Saudi Arabia and the broader Middle East and North Africa (MENA) region. Timed to coincide with Saudi Arabia’s state visit to France, the initiative supports the Kingdom’s Vision 2030 framework to establish localized, sovereign high-performance computing (HPC) and artificial intelligence infrastructure. Operational MetricJoint Venture DetailJoint Venture NamePasqal ArabiaBoard ChairmanshipHRH Prince Abdulaziz Bin Turki Bin Talal (Founder, Eleven Ventures)Corporate PartnersPasqal & Eleven VenturesDeployment FootprintKingdom of Saudi Arabia & MENA regionPrimary FocusOn-premises neutral-atom QPU deployment, AI convergence, and local talent developmentNasdaq SPAC PartnerBleichroeder Acquisition Corp. II (Nasdaq: BBCQ) On-Premises Infrastructure and Regional Workforce Scaling The joint venture establishes a commercial conduit to deploy multiple on-premises quantum computing systems directly within Saudi Arabia rather than relying solely on remote cloud access: Sovereign High-Performance Computing: Pasqal Arabia will integrate neutral-atom quantum hardware alongside high-performance classical computing and AI infrastructure to meet regional enterprise and government demand. Local Capability & Talent Pipeline: The entity will build dedicated technical expertise and workforce development programs within the Kingdom, training domestic quantum engineers and researchers to operate native installations. Diplomatic & Strategic Alignment: The agreement was highlighted during a diplomatic delegation visit by Saudi Arabian officials to Pasqal’s headquarters and QPU manufacturing fac
