13 Quantum Computing Startups To Watch In 2024

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.
