Quantum computers promise to be able to solve problems that classical computers either cannot solve or would take many years to solve. While classical computers use binary bits (ones and zeros) to store and process data, quantum computers can encode much more data at once using quantum bits, or qubits, in superposition.
There is a good reason many investors are eager to invest in this emerging technology. The global quantum computing market for hardware and software is projected to reach $90 billion to $170 billion by 2040, according to the Boston Consulting Group (BCG). This market was valued at approximately $1.4 billion in 2024, according to Grandview Research. So, BCG’s estimate corresponds to a compound annual growth rate (CAGR) of about 30% to 35%.
Much of this growth is likely to occur in the backend of the period provided. Quantum computing is in its early stages, and several issues need to be addressed before it becomes a practical technology for solving problems efficiently.
Monitoring patent activity can be a valuable tool for investors, particularly for those interested in emerging technologies. Patents grant inventors a monopoly on their inventions for a specified period of time.
Of course, monitoring patent activity is just one tool in a tech investor’s toolkit. It certainly doesn’t replace reviewing a company’s quarterly reports. Monitoring liquidity metrics — such as cash flows, cash on the balance sheet, and cash burn — is particularly critical for companies that are not yet profitable.
That said, let’s dive into the patent activity of the major quantum computing players, both the pure plays — such as IonQ (NYSE: IONQ), Rigetti Computing (NASDAQ: RGTI), and D-Wave Quantum (NYSE: QBTS) — and the non-pure-plays, including big technology companies IBM (NYSE: IBM), Alphabet (NASDAQ: GOOG)(NASDAQ: GOOGL), Microsoft (NASDAQ: MSFT), and Amazon (NASDAQ: AMZN).

IBM and Alphabet were light-years ahead of other companies in terms of 2024 U.S. quantum computing patents. Indeed, IBM and Alphabet are widely regarded as leaders in the quantum computing space, as I mentioned in my January 2025 article on the Defiance Quantum exchange-traded fund (ETF).
-
Among the pure-play quantum computing companies, Rigetti had the most U.S. quantum patents obtained in 2024. However, D-Wave’s total number of U.S. quantum computing patents exceeds those of both Rigetti and IonQ.
