But a “quantum” label does not guarantee pure exposure: a fund may also hold semiconductor makers, large technology companies, machine-learning firms, or quantum-ready security businesses. Compare its mandate, holdings, costs, risks, and local availability before deciding.
How a fund can give you quantum-computing exposure
An ETF pools investors’ money to hold a basket of securities. Buying fund shares can therefore spread your exposure across several companies rather than tying it to one quantum-computing stock. The fund’s actual exposure depends on how its manager defines the theme and selects or weights holdings.
That distinction matters because quantum computing is still an emerging investment theme. In its 2026 report, the European Securities and Markets Authority (ESMA) said only five additional EU-based funds among more than 35,000 analyzed fund disclosures explicitly named quantum computing as an investment theme, in addition to three new dedicated quantum UCITS ETFs. The three new ETFs had combined assets under management of USD 0.6 billion at the end of March 2026. Those figures describe the EU funds ESMA analyzed, not the whole global fund market. ESMA’s report
Compare the fund’s definition of “quantum”
Products with similar names can have different mandates. Some track an index spanning quantum computing and machine learning; others actively select companies and may include quantum-related cybersecurity. A broader mandate can provide exposure to businesses that support or may benefit from the technology, but it may mean less direct exposure to companies focused on quantum computing itself.
#1 Best Overall
| Fund example | Mandate and approach | Published fee or fund details | What to examine |
|---|---|---|---|
| Defiance Quantum ETF (QTUM) | Seeks to track the BlueStar Quantum Computing and Machine Learning Index before fees and expenses; passive strategy. Its index was concentrated in semiconductors as of 2026-03-31. | 0.40% total annual operating expenses in the SEC-filed summary prospectus dated 2026-04-30. | Index rules and weighting; current semiconductor, machine-learning, and quantum exposure; trading costs and availability. SEC-filed prospectus |
| Corgi Quantum Computing ETF (CQTM) | Actively managed. Its ordinary-course policy is to invest at least 80% of net assets in companies materially involved in quantum computing, quantum-enabled technologies, and quantum-ready security. The fund says it is non-diversified. | Expense figure: not stated in the cited summary prospectus. | How the manager defines eligible companies, the security component, holdings, concentration, and liquidity. SEC-filed prospectus |
| iShares Quantum Computing UCITS ETF (QANT) | Aims to reflect the STOXX Global Quantum Computing Index. | BlackRock lists a 0.50% total expense ratio for the cited share class, which is Ireland-domiciled, UCITS-compliant, semi-annual rebalancing, and accumulating income. Provider page accessed 2026-10-04. | Index methodology and ESG screening; share class, trading currency, local eligibility, and geographic and currency exposure. BlackRock fund page |
| WisdomTree Quantum Computing Fund (WQTM) | WisdomTree says it invests primarily in quantum-computing companies and invests in index securities regardless of individual investment merit; it does not attempt to outperform its index. | Expense figure: not stated in the cited provider page. | Current fund structure, index, holdings, fees, and how much company revenue is actually tied to quantum computing. WisdomTree fund page |

Use a checklist before choosing
- Read the mandate and index rules. Establish whether the fund is passive or actively managed, what qualifies a company for inclusion, how holdings are weighted, and whether the strategy also covers semiconductors, machine learning, or security.
- Inspect current holdings. Look at the actual companies, their weights, country and currency exposure, company size, and how much of their business is attributable to quantum computing. A fund name alone cannot establish how closely its holdings match your intended exposure.
- Compare the full cost. Check the latest expense ratio or operating expenses, plus any trading costs and share-class features. The stated annual fund charge is not necessarily the only cost of owning or trading the investment.
- Confirm access and local treatment. Check whether the fund and specific share class can be bought through your account in your country. Domicile, listing market, currency, tax treatment, and investor eligibility differ; the examples above do not establish which one you can access or whether it suits your circumstances.
- Read the risk disclosures and consider your own limits. Compare the fund’s disclosed risks with your time horizon and ability to withstand losses. The SEC’s Investor.gov guide to non-traditional index funds recommends reviewing costs, risks, index construction, actual holdings, and fit with investment goals.
Understand what a basket does—and does not—reduce
Holding a basket can reduce dependence on any one issuer, but it does not eliminate equity-market risk or the possibility that a narrow technology theme underperforms. A fund may be concentrated in a small set of companies or adjacent industries. There is also uncertainty about whether quantum-related products will produce material revenue or improve the economics of companies that invest in them.

The specific disclosures vary. The Defiance prospectus describes concentration, emerging-technology, equity-market, and currency risks, and notes that few public companies currently have significant attributable revenue or profit streams from emerging technologies such as quantum computing. Corgi identifies itself as non-diversified and warns that concentration can increase sensitivity to adverse market or sector developments. BlackRock identifies technology change, intellectual-property protection, regulation, competition, and concentration risks for QANT. WisdomTree warns about rapid advances, obsolescence, competition, demand, regulation, and dependence on patents and intellectual property in quantum-computing and machine-learning firms.
Targeted or non-traditional index strategies can be complex, may have limited track records, and are not assured to outperform traditional market indexes, according to Investor.gov. No thematic fund guarantees that investors will benefit if quantum computing becomes more widely adopted.
