13 quantum computing startups to watch in 2026 rankred

The current state of the quantum computing industry is dynamic and promising. According to a study by McKinsey, four sectors — finance, chemical, life sciences, and mobility — are poised to experience the earliest impacts of quantum computing, potentially adding up to $2 trillion by 2035. In 2023, quantum technology startups raised $1.71 billion through approximately 171 deals, with an average deal size being $40 million. These figures are based on publicly available investment data from Pitchbook, so the actual investment may be even higher. [1] Public investments account for nearly one-third of all investments in quantum technology.

Countries like the United States, Canada, South Korea, Germany, and the United Kingdom, have made substantial investments to advance this field, bringing the global funding total to nearly $42 billion. The majority of the funding has been raised by US companies, securing twice the amount compared to the next leading country. Following the US, companies in Canada and the UK have attracted significant investments. Here, we highlight some of the fastest-growing quantum computing startups that are making a significant impact on the industry by focusing on specific aspects of quantum technology, such as quantum cryptography and specialized hardware. Quantum computing continues to move from research labs into early commercial applications. Several companies are competing to develop viable quantum systems that can solve problems traditional computers cannot handle.

The technology remains complex and expensive. However, major tech firms and startups are making measurable progress in reducing error rates and building practical quantum computing systems. IonQ leads the quantum computing industry in accuracy. The company achieved 99.99% two-qubit gate fidelity in October 2025. No other quantum computing company has crossed the 99.9% threshold yet. This accuracy matters because error correction is the biggest challenge preventing quantum computers from widespread use.

IonQ uses trapped-ion technology, which provides good stability for qubits. The company reached the 99.9% fidelity mark in September 2024. Other companies following similar timelines would give IonQ roughly a one-year advantage. IonQ offers its quantum systems through major cloud platforms, giving it access to early customers. The company operates as a pure-play quantum computing firm. The quantum computing industry is growing with companies developing new types of computers.

These businesses are located worldwide, including in the United States, Europe, and Australia. Some companies have attracted large investments, like PsiQuantum which has raised $2.3 billion. SandboxAQ and Quantinuum have also secured nearly one billion dollars each to fund their work. Below is our list of 53 Quantum Computing startups worth keeping an eye on. Headlines these days highlight pure-play quantum computing startups racing to build fault-tolerant machines. But history suggests that the earliest and most durable value creation in emerging compute paradigms rarely accrues to the system builders alone.

In the near-to-medium term, quantum workloads will be highly dependent on classical infrastructure, advanced semiconductor manufacturing, precision test and packaging and secure enterprise-grade IT environments. For investors, this makes 2026 less about picking a single quantum winner and more about identifying the enablers positioned to capture real revenues as quantum transitions from laboratory experiments to early commercial deployment. Names to watch include Advanced Micro Devices AMD, Teradyne TER, Broadcom AVGO, Applied Materials AMAT and Oracle ORCL. In 2026, investors should also watch companies whose core businesses are not quantum computers per se, but provide the technologies that make quantum progress possible. These include essential enablers like Graphics Processing Units (GPUs) and High-Performance Computing (HPC) engines, semiconductor test and packaging equipment, materials and fabrication specialists and vendors of quantum-safe security. At the same time, progress in qubit fidelity and scaling is driving demand for sophisticated test, measurement and automation systems as well as advanced materials, deposition and etching technologies that can deliver repeatable, low-defect...
