Quantum Computing Inc. QUBT or “QCi” is continuously investing in research and development (R&D) to strengthen its position in quantum photonics and scalable quantum computing. During the first quarter of 2026, the company expanded its engineering, scientific and technical workforces, contributing to a 133.5% year-over-year increase in research and development expenses.
One of QCi's primary R&D initiatives is the development of the next version of its Dirac quantum optimization platform. QCi is also advancing its gate-based quantum computing program, which aims to create a scalable, room-temperature quantum computer using photonic technology. Research efforts are focused on two key areas — improving gate fidelity through advanced engineering design and developing ultra-high-quality photonic integrated circuits based on thin-film lithium niobate (TFLN) technology.
The company’s fabrication facility (Fab 1) serves primarily as an R&D and technology validation center rather than a revenue-generating manufacturing operation. QCi uses Fab 1 to develop and stabilize fabrication processes that will eventually be transferred to a larger-scale Fab 2 facility designed for volume production.
QCi’s recent acquisitions of Luminar Semiconductor and NuCrypt have significantly expanded its research talent base and technical capabilities, supporting a vertically integrated approach to quantum technology development.
Peer Update
Rigetti RGTI achieved a two-qubit gate fidelity as high as 99.9% at 28-nanosecond gate speed on a prototype platform using its new proprietary adiabatic CZ scheme. Rigetti made strong progress toward deployment of its 108-qubit chiplet-based quantum system, advancing both performance validation and system-level integration. Rigetti continued collaborating with Riverlane on error correction research, focusing on system-level integration and long-term scalability.
D-Wave Quantum QBTS continues to advance its annealing platform through Advantage2 and the Leap cloud service. The company is expanding its product portfolio into gate-model quantum computing following the Quantum Circuits acquisition in January 2026. QBTS is targeting roughly 175 physical qubits by the end of 2028 to demonstrate error correction and logical operations. D-Wave continues to add commercial annealing applications in production and expand research use cases, including work in quantum AI and blockchain benchmarking.
