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.

Syremis Therapeutics is advancing a neuropsychiatric pipeline grounded in clinically validated mechanisms, aiming to create best-in-class treatments for schizophrenia, major depressive disorder, bipolar depression and other psychiatric conditions. Its lead asset, ST-905, is a potent dual M1/M4 muscarinic receptor agonist now in Phase 1 trials and designed for once-daily oral dosing with the potential for a long-acting injectable formulation. A second program, ST-901, is a next-generation NMDA antagonist in IND-enabling studies and slated to enter Phase 1 next year to address depressive disorders. Both candidates originated at Clexio Biosciences before being spun out to Syremis. The company highlights the vast unmet need in schizophrenia, which affects more than 20 million people globally, and cites limitations in efficacy and tolerability of current therapies as its market entry point. Syremis is led by a seasoned team including co-founders Elisabeth Kogan (CEO), Elena Kagan (CDO), and Menashe Levy (CTO), with board members drawn from Dexcel Pharma, Third Rock Ventures, Bain Capital Life Sciences and other industry leaders. Its $165 million Series A financing provides the capital to advance both programs through clinical proof of concept. No commercial revenues or patient enrollment figures have been disclosed to date.

QuEra Computing is a Boston-based quantum technology company that has pioneered a neutral-atom platform capable of room-temperature operation, wireless laser control and dynamic qubit rearrangement. In 2025 the firm, in partnership with Harvard, MIT and Yale, demonstrated continuous operation of a 3,000-qubit array, integrated fault-tolerant architecture with 96 logical qubits, logical magic-state distillation and a new algorithmic fault-tolerance framework, collectively resolving the main barriers to large-scale quantum computing. QuEra’s systems, such as the cloud-accessible Aquila and the on-premises Gemini-class machine installed at AIST in Japan, are already powering dozens of peer-reviewed scientific papers and hybrid HPC workflows. Commercial traction accelerated in 2025 with record revenue and cash collections from product and service deliveries, and the company has doubled its global workforce. Looking ahead, QuEra plans to unveil third-generation systems in 2026–2027 featuring large numbers of high-quality logical qubits for classically intractable problems. The company operates globally from Boston, Tokyo and the United Kingdom while expanding its Quantum Alliance with partners like BCG X and Deloitte Japan.
