CavilinQ is developing cavity-enhanced photonic links that aim to connect individual quantum processors into unified, modular clusters to enable larger-scale quantum computing. The platform is described as hardware-agnostic, with initial demonstrations planned for integration with neutral atom quantum processors. Its technology builds on high-fidelity light-matter interfaces advanced by scientific co-founders Mikhail Lukin and Hannes Bernien. The company plans to establish a specialized laboratory in Cambridge, Massachusetts, expand its team, and reach key technical milestones. CavilinQ announced a completed $8.8 million seed round to fund these efforts. The company positions its interconnects as enabling distributed quantum architectures that could scale performance and reliability beyond isolated processors.

Monarch Quantum, founded in 2025 and based in San Diego, develops integrated photonics systems called Quantum Light Engines™ that provide precise photonic control for quantum computing, sensing, and networking. The company combines photonics components, systems engineering, and advanced packaging to move laboratory-scale photonics setups to manufacturable hardware. Monarch entered 2026 with more than $60 million in customer contracts from customers including Quantinuum, Infleqtion and NASA, bringing total capital and contracts to over $115 million after the $55 million growth round. Its customer base includes quantum OEMs, national laboratories, defense integrators, and advanced research institutions. Leadership is led by photonics veteran Dr. Timothy Day, whose prior team commercialized Daylight Solutions (acquired by Leonardo DRS in 2017). Monarch plans to scale production, expand its supply chain, and pursue global partnerships to become a core hardware infrastructure supplier for the quantum ecosystem.

Delta.g is a Birmingham-based quantum technology spin-out from the University of Birmingham that builds quantum sensors engineered for real-world deployment. Its proprietary devices provide significant gains in precision, portability and reliability, enabling quantum-grade geospatial data collection. Early trials have demonstrated value across infrastructure monitoring, transportation, and other dual-use government and commercial scenarios. The hardware is paired with a data and analytics layer that integrates sensor outputs directly into customers’ decision-making workflows. With newly raised capital the company plans to expand its technical team, scale manufacturing capacity and deliver pilot field systems through key partners. It also intends to advance its analytics platform to support broader adoption. To date, Delta.g has secured £4.6 million in seed funding; the article did not disclose additional operating metrics such as revenue or user numbers.

Formed in 2021 through the merger of Honeywell Quantum Solutions and Cambridge Quantum, Quantinuum provides end-to-end quantum computing products and services. The company sells hardware and software, developer tools, and applications—its platform includes InQuanto, a tool for computational chemistry. Quantinuum is preparing to launch Helios, a next-generation quantum system intended to advance performance and move toward universal fault-tolerant quantum computing. The firm is expanding its global footprint and has announced partnerships and collaborations to explore hybrid and scalable quantum-classical models. Notable collaborations include work with NVIDIA at the Accelerated Quantum Research Center in Boston and partnerships with RIKEN, SoftBank Corp., Infineon Technologies, and the STFC Hartree Centre. Quantinuum is also expanding regionally with activity in New Mexico, Qatar (including a role in a $1 billion national initiative), and Singapore. Quantinuum is an integrated quantum computing company that develops quantum hardware and advanced software solutions to drive applications in materials discovery, cybersecurity, and next‑generation quantum AI. Led by CEO Rajeeb Hazra and based in Broomfield, Colorado, the company supplies technologies to firms including Airbus, BMW Group, Honeywell, HSBC, JPMorgan Chase, Mitsui and Thales. Quantinuum employs almost 500 people, including over 370 scientists and engineers. The company closed a $300m equity funding round at a $5 billion pre‑money valuation, bringing total capital raised since inception to approximately $625m. The round was anchored by strategic partner JPMorgan Chase, with participation from Mitsui & Co., Amgen, and Honeywell, which remains Quantinuum’s majority shareholder. Quantinuum intends to use the proceeds to accelerate the path toward universal fault‑tolerant quantum computers and to extend its software offering to enhance commercial applicability.
