As of October 8, 2026, the products identified here are two U.S.-listed funds—Defiance Quantum ETF (QTUM) and Corgi Quantum Computing ETF (CQTM)—and two UCITS funds: VanEck Quantum Computing UCITS ETF (QNTM) and iShares Quantum Computing UCITS ETF (QANT). They differ in investment approach and market access, and none should be assumed to hold only companies whose businesses are devoted to quantum computing. Check each fund’s current documents and your local exchange before investing.
The original title’s “for 2025” is out of date: the product information discussed here includes filings and listings from 2026. This is a dated guide to four identified funds, not a claim to cover every quantum-themed ETF worldwide. Fund names, holdings, fees and availability can change.
Which quantum computing ETFs are identified?
| Fund | Market and approach | What its stated exposure means | Documented details |
|---|---|---|---|
| Defiance Quantum ETF (QTUM) | U.S.-listed; seeks to track an index | The BlueStar Quantum Computing and Machine Learning Index combines quantum-computing and machine-learning exposure. | Defiance’s factsheet reports a 0.40% expense ratio and 83 holdings, both as of December 31, 2025. These are dated figures, not confirmed current values. |
| Corgi Quantum Computing ETF (CQTM) | U.S.-listed; actively managed | Cboe describes exposure across quantum hardware, cryogenics and software, as well as post-quantum cryptography and secure communications. | Cboe gives May 6, 2026 as its listing date. A comparable current fee and holdings count are not stated in the cited sources. |
| VanEck Quantum Computing UCITS ETF (QNTM) | UCITS product; access depends on market and share class | Its holdings need not be pure-play quantum companies. VanEck’s February 28, 2026 factsheet lists Samsung Electronics, IonQ, Deutsche Telekom and Honeywell among its top holdings. | The factsheet is a dated snapshot and directs investors to VanEck for the complete current holdings list. A comparable fee and holdings count are not stated here. |
| iShares Quantum Computing UCITS ETF (QANT) | UCITS product; listing, currency and share class depend on market | The product is identified on the iShares UK professional fund page; review its current fund documents to understand its exposure. | A current fee and holdings count are not established here. |

How do QTUM and CQTM differ?
QTUM follows an index
In its April 30, 2026 summary prospectus, Defiance says QTUM seeks to track, before fees and expenses, the total return performance of the BlueStar Quantum Computing and Machine Learning Index. That objective includes machine learning alongside quantum computing; the fund’s name alone does not mean the portfolio is narrowly focused on quantum hardware makers. See the SEC summary prospectus and the issuer factsheet.

The 0.40% expense ratio and 83-holding count in Defiance’s factsheet are both dated December 31, 2025. Because they are not synchronized with the later prospectus date, treat them as historical reference points and verify current costs and holdings with the issuer before comparing QTUM with another fund.
CQTM is actively managed
Corgi’s April 30, 2026 summary prospectus states that CQTM seeks capital appreciation. Cboe says the fund was listed on May 6, 2026 and describes its exposure as spanning quantum hardware, cryogenics and software, alongside post-quantum cryptography and secure communications. Those categories are Cboe’s description, not a guarantee that every holding is a pure-play quantum business. Consult the SEC summary prospectus and Cboe listing for fund-specific information.
Rank #2
What should investors know about the UCITS funds?
QNTM and QANT are UCITS products, rather than interchangeable U.S.-listed share classes. A fund’s home market, exchange listing, trading currency and share class can affect whether an investor can buy it and which listing is relevant. Availability also depends on local rules and the investor’s broker; a ticker on one exchange does not establish access in another country.
VanEck’s February 28, 2026 QNTM factsheet names Samsung Electronics, IonQ, Deutsche Telekom and Honeywell among its top holdings. That snapshot illustrates why a “quantum” label does not necessarily mean a portfolio consists exclusively of companies deriving revenue from quantum computing. VanEck says to consult its current information for the complete holdings list. See the QNTM factsheet.
iShares identifies QANT on its UK professional fund page. Check that page and the relevant exchange listing for the latest documents, share class and trading details before relying on a ticker or product statistic.
How to compare funds before investing
- Read the objective and method. Determine whether the fund tracks an index or is actively managed, and read what the index or mandate counts as quantum-related exposure.
- Inspect current holdings. Look beyond the fund name. Check the full holdings list, the date it represents and the weight of the largest positions. Adjacent areas such as machine learning, semiconductors, communications or security may contribute to a fund’s theme.
- Verify all-in costs. Compare the current expense ratio or other stated fund charges using issuer documents with the same effective date. Brokerage commissions, bid-ask spreads and currency conversion may also matter, depending on the listing and account.
- Confirm the correct listing and eligibility. Check domicile, exchange, share class and trading currency, then confirm with your broker that the specific product is available to you.
- Read the prospectus risks. Review the fund’s own risk disclosures, including the risks associated with its investment strategy and underlying securities. A thematic label is not a substitute for understanding what can drive the fund’s value.
The available figures do not support a like-for-like performance, assets-under-management or live-holdings comparison across these four funds. Avoid ranking them on those measures without current, comparable issuer data.

An ETF provides exposure to a basket of securities under its stated objective or strategy; it does not establish that quantum computing will be adopted on a particular schedule or that companies in the portfolio will benefit commercially. A theme can span businesses with different activities and varying degrees of connection to quantum technology. Consider the underlying holdings and the fund’s risks, rather than treating the name as a forecast or a measure of revenue purity.
This list is informational, not a personalized investment recommendation. Fund details and market access can change, so use the latest prospectus, factsheet and exchange information for the exact listing you are considering.
