Investing in quantum AI technologies: Ways to seek potential exposure and companies to follow
You can't be in two places at once…unless you're operating at the subatomic level of quantum mechanics. This principle, known as quantum superposition, is also helping to fundamentally advance computing. And investors may encounter companies exploring the intersection of quantum computing and AI.
Quantum computing is still in the very early stages, given the extreme difficulty of controlling the qubits that can make data processing dramatically faster. Yet similar to how AI went from a research topic in the 1950s to seemingly an overnight sensation with ChatGPT's public debut in 2022,1 quantum computing has been in R&D since around the 1980s and is getting closer to more mainstream applications.2
When combined, quantum computing could potentially make AI itself more efficient and effective by running certain workloads on quantum processors.3 Because quantum computing enables analysis of multiple scenarios simultaneously, that may help overcome some of the scaling constraints and difficulty of working with limited information that AI currently faces. Quantum AI is being examined in experimental settings for potential business applications, including drug discovery research and financial portfolio optimization.4
While outcomes remain uncertain, a range of startups and established technology companies are actively conducting research into quantum computing and artificial intelligence. This guide examines how some organizations are approaching this emerging area and the considerations involved as the technology continues to develop.
How to potentially gain exposure to quantum AI technologies
There are several ways to seek exposure to quantum AI technologies as both an accredited investor or as a non-accredited retail investor, such as the following:
Investing in private market startups
For accredited investors, investments in certain private market companies may offer indirect exposure to businesses involved in quantum AI‑related research and development. Some of these startups are primarily focused on quantum technologies that could still be used by other companies in an AI context, but they don't necessarily provide direct exposure to the hybrid quantum AI market. Others do operate more at the intersection of these fields.
Some examples include:
(See the section "Private companies involved in quantum AI technologies for more details on these startups.")
Investing in public market companies
Another potential option, available to both accredited and retail investors, is gaining exposure through publicly traded companies engaged in quantum computing and AI research. This includes large technology firms such as Alphabet, Amazon, IBM, and Microsoft, which pursue quantum‑related initiatives alongside a wide range of other businesses, resulting in potential indirect and diversified exposure.
Also, some publicly traded companies focus more specifically on quantum computing, including IonQ, D‑Wave Computing and Rigetti Computing. These firms center their activities on quantum technologies and, in certain cases, also engage with artificial intelligence–related systems. For example, Rigetti has announced a collaboration with NVIDIA related to technologies intended to support connections between AI supercomputing infrastructure and quantum computing systems.5
In addition, certain publicly traded funds, such as the Defiance Quantum ETF (QTUM), hold baskets of companies involved in quantum computing and machine learning or AI. Exposure levels vary by issuer, and the degree of overlap between quantum and AI technologies may evolve over time.6
Who can invest in private companies doing quantum AI?
Investment in private companies doing quantum AI is typically limited to accredited investors, due to U.S. regulations that generally restrict the offer and sale of private company securities to such investors.
Some large accredited investors, such as VC funds and certain high-net-worth individuals, may be able to invest in quantum AI companies if selected to participate in primary funding rounds or strategic investment partnerships. Smaller accredited investors may consider buying stock in private companies engaged in quantum AI through a private stock marketplace like Forge, subject to the availability of shares.

Quantum Machines
Quantum Machines, founded in 2018 and based in Israel,11 sells control hardware and software that helps enable quantum R&D. The company's mission is to build a quantum orchestration platform "that powers quantum breakthroughs and accelerates the path towards the new age of quantum computing."12 That also blends into the AI side, such as with Quantum Machines partnering last year with quantum processor company Diraq to deploy a system that achieved ultra-fast communication between quantum hardware and NVIDIA Grace-Hopper superchips.13
At this time, Quantum Machines' Forge Price is unknown. However, Forge has tracked Quantum Machines' funding rounds, such as with the company most recently raising its Series C in February 2025. This round raised $153.04 million at a $664.68 million valuation, with investors including PSG Equity, Intel Capital, Red Dot Capital Partners and TLV Partners.14
