You can invest in quantum computing without choosing individual company shares by buying a pooled fund, most commonly a thematic exchange-traded fund (ETF). But “quantum” funds do not all own the same kinds of businesses: some include semiconductor and machine-learning companies, and one example also includes quantum-ready security firms. Compare a fund’s mandate, holdings, costs, risks and local availability before deciding; a basket can reduce reliance on one issuer, but it does not remove investment risk.
What investing through a quantum fund means
A thematic fund pools investors’ money and holds a basket of securities selected under its stated strategy. You buy shares or units of the fund rather than selecting each company yourself. The fund’s label is only a starting point: its holdings may include businesses involved in quantum computing alongside semiconductor suppliers, broad technology companies, machine-learning businesses or security firms.

That distinction matters because a fund can have meaningful exposure to industries related to quantum computing without depending on quantum-related sales for most of its returns. The SEC’s Defiance Quantum ETF summary prospectus says that only a few public companies currently have significant attributable revenue or profit streams from emerging technologies such as quantum computing, and that the technologies may not materially affect some portfolio companies’ economic returns.

#1 Best Overall
| Fund | Stated approach | What to examine |
|---|---|---|
| Defiance Quantum ETF (QTUM) | The SEC-filed summary prospectus dated 2026-04-30 says it passively seeks to track the BlueStar Quantum Computing and Machine Learning Index before fees and expenses. Its cited total annual operating expenses are 0.40%. The index was concentrated in semiconductors as of 2026-03-31. | Index rules and weighting; how much exposure is to semiconductors, machine learning and quantum computing; current holdings; expenses and trading costs; jurisdiction and account availability. SEC summary prospectus. |
| Corgi Quantum Computing ETF (CQTM) | The SEC-filed summary prospectus describes active management and an ordinary-course policy to invest at least 80% of net assets in companies materially involved in quantum computing, quantum-enabled technologies and quantum-ready security. The fund describes itself as non-diversified and identifies concentration risk. | How the manager selects securities; what qualifies as quantum or security exposure; holdings, company size and liquidity; concentration, costs and prospectus risks. SEC summary prospectus. |
| iShares Quantum Computing UCITS ETF (QANT) | BlackRock says the fund aims to reflect the STOXX Global Quantum Computing Index. Its cited page lists Ireland domicile, UCITS compliance, semi-annual rebalancing, and accumulating income for the cited share class. The page lists a 0.50% total expense ratio for that share class. | Index rules and any screening; domicile and UCITS status; share classes, trading currency and local eligibility; current holdings, geographic and currency exposure, and charges. BlackRock fund page. |
| WisdomTree Quantum Computing Fund (WQTM) | WisdomTree says the fund invests primarily in quantum-computing companies and holds index securities regardless of individual investment merit. Its provider page warns of technology, obsolescence, competition, demand, regulatory and intellectual-property risks. | Current fund structure and index; holdings and concentration; quantum-related revenue exposure; current prospectus and fees. WisdomTree fund page. |
The expense figures shown are from different funds and jurisdictions, and do not by themselves indicate which fund is cheaper to own overall. Verify current charges in the latest documents and account for trading costs and any share-class differences.
What to check before investing
- Read the fund’s current prospectus and reports. Confirm its objective, eligibility, strategy, risks and charges. A fund name is not a substitute for its legal investment mandate.
- Inspect actual holdings. Look at the companies and industries represented, their weights, and whether the fund’s exposure is chiefly to quantum businesses or to adjacent areas such as semiconductors and broader technology.
- Understand how securities are selected and weighted. An index fund follows stated index rules; an actively managed fund relies on its manager’s selection process. Neither approach guarantees a return or a closer link to quantum-related revenue.
- Compare costs and share-class details. Check the expense ratio or total expense ratio, other fund charges, trading costs, income treatment and trading currency for the share class you are considering.
- Check domicile, listing and local access. Availability depends on your country, residency, brokerage account and the specific share class. Tax treatment and suitability also depend on personal and local circumstances.
- Consider risk and time horizon. Decide whether you can tolerate losses and a potentially narrow, volatile theme as part of your overall investment plan.
The SEC’s Investor.gov guidance on non-traditional index funds recommends examining fund costs, risks, index construction and holdings, and whether the fund fits your investment goals. It also cautions that targeted strategies can be complex, may have limited track records and need not outperform traditional market indexes. Read the guidance.
Rank #2
Why a basket does not make the theme low-risk
A fund can spread exposure across several issuers, reducing dependence on any one company, while remaining concentrated in a narrow technology theme or related industries. Its value can fall with equity markets, and its holdings can be affected by rapid technological change, competition, regulation, concentration and uncertainty about whether quantum computing will produce meaningful commercial revenues.
The fund disclosures illustrate different versions of that risk. Defiance identifies emerging-technology, concentration, equity-market and currency risks. Corgi warns that its non-diversified structure can make it more sensitive to adverse developments affecting a company or sector. BlackRock identifies technology change, intellectual-property protection, regulation, competition, and concentration in sectors, countries, currencies or companies. WisdomTree highlights rapid advances, product obsolescence, demand, regulation and reliance on patents and intellectual property. Review the disclosures for the specific fund rather than assuming that diversification across holdings removes these risks.

ESMA reported that three EU-domiciled quantum-focused ETFs launched in 2025 and together had USD 0.6 billion in assets under management at the end of March 2026. In its analysis of disclosures from 35,189 EU-domiciled funds, ESMA also found five additional EU-based funds that explicitly named quantum computing as an investment theme, beyond those three dedicated UCITS ETFs. This is a dated snapshot of EU-domiciled funds, not a count of every quantum-related investment product worldwide. Read ESMA’s report.
