The study involved four major activities in estimating the size of the quantum computing market. Exhaustive secondary research has been done to collect information on the market, peer, and parent markets. The next steps are to validate these findings, assumptions, and size with industry experts across the value chain through primary research. Both top-down and bottom-up approaches have been employed to estimate the global market size. After that, market breakdown and data triangulation have been used to estimate the market sizes of segments and subsegments.
Secondary sources for this research study include corporate filings (such as annual reports, investor presentations, and financial statements), trade, business, and professional associations, white papers, certified publications, articles from recognized authors, directories, and databases. Secondary data was collected and analysed to determine the overall market size, further validated by primary research.
Extensive primary research was conducted after understanding and analysing the quantum computing market scenario through the secondary research process. Several primary interviews were conducted with key opinion leaders from the demand- and supply-side vendors across four major regions—North America, Asia Pacific, Europe, and RoW (including the Middle East, Africa, and South America). After interacting with industry experts, brief sessions were conducted with highly experienced independent consultants to reinforce the findings from our primary research. This and the in-house subject matter experts’ opinions have led us to the findings described in the remainder of this report.
Note: Three tiers of the companies were defined based on their total/segmental revenue as of 2024; Tier 1 = >USD 1 billion, Tier 2 = USD 1 billion–USD 500 million, and Tier 3 = USD 500 million. Others include sales, marketing, and product managers.

Both top-down and bottom-up approaches have been used to estimate and validate the total size of the quantum computing market. These methods have also been extensively used to estimate the sizes of various market subsegments. The research methodology used to estimate the market sizes includes the following:

The market has been split into several segments and subsegments after arriving at the overall market size, using the market size estimation processes explained above. Data triangulation and market breakdown procedures have been employed to complete the overall market engineering process and arrive at the exact statistics of each market segment and subsegment, wherever applicable. The data has been triangulated by studying various factors and trends from both the demand and supply sides.
Quantum computing involves phenomena such as quantum entanglement and quantum mechanics superposition that quantum computers use for their enhanced computing power. The improved computing power of quantum computers can be attributed to how data is represented. Conventional computers use bits that can either be 1s or 0s, while quantum computers use qubits (quantum bits), which can be both 0s and 1s simultaneously due to superposition. Quantum computing devices or quantum computers operate with nanoscale components at low temperatures, and they have the potential to address some of the most challenging computational problems.
