A quantum computing ETF is an exchange-traded fund that holds publicly traded companies selected for a connection to quantum computing or related technologies. It lets investors buy a single fund share for exposure to a basket of companies, but there is no standard definition of “quantum computing” across funds. To understand what a particular ETF owns, check its prospectus and, for an index fund, the index methodology—not just the name.
How a quantum computing ETF works
An ETF pools investors’ money and holds a portfolio of securities. Its shares trade on an exchange, while the portfolio’s holdings and investment mandate determine the exposure it provides. A quantum-themed ETF applies a stated strategy to select companies it considers connected to quantum computing, quantum-enabled technologies, or related areas.
The strategy can be index-based or actively managed. An index ETF aims to track a benchmark before fees and expenses; an active ETF gives its adviser discretion to choose investments within the fund’s mandate. Neither approach guarantees that the companies will succeed or that the ETF’s share price will rise.
How funds define the quantum theme
“Quantum computing ETF” is a theme, not a standardized portfolio category. Depending on the fund, eligible companies may include businesses involved in quantum hardware, software, components, algorithms, networking, sensing, or security. Some funds also include adjacent areas such as machine learning or specialized semiconductors; others include post-quantum cryptography and quantum-ready security.
#1 Best Overall
That difference can materially change a fund’s holdings. A company included because it works on machine learning or semiconductor technology may not have the same exposure to quantum computing as a company developing quantum hardware. Read the fund’s definition of eligible companies and look at its current holdings to see what the theme means in practice.
How selection approaches differ
Index-tracking funds
An index ETF follows a named benchmark and its rules. Defiance Quantum ETF (QTUM), for example, tracks the BlueStar Quantum Computing and Machine Learning Index. Its prospectus describes a modified equal-weighted portfolio and a screen of globally listed companies based on business activity. The index screens semi-annually, with market-capitalization thresholds that differ between quantum-computing and machine-learning-related companies. The fund uses a passive approach: it generally follows the index rather than selling a company solely because its adviser expects it to underperform. See the Defiance Quantum ETF prospectus for the strategy and index details.
Actively managed funds
An active ETF’s adviser selects investments according to the fund’s stated mandate rather than simply replicating an index. The Corgi Quantum Computing ETF (CQTM) seeks capital appreciation and says that, under ordinary market conditions, it invests at least 80% of net assets in companies materially involved in quantum computing, quantum-enabled technologies, and related security solutions. Its stated scope includes hardware, components, software, algorithms, networking, sensing, and post-quantum cryptography. The 80% policy and the fund’s definition are described in its summary prospectus.
Different listings and jurisdictions
Funds with quantum-related names are not necessarily available to the same investors or governed by the same rules. BlackRock describes QANT as an international UCITS fund benchmarked to the STOXX Global Quantum Computing Index. Its structure and geographic availability are distinct from the U.S. fund examples above; consult the BlackRock product page for its current product information.

| Comparison point | What to check |
|---|---|
| Objective and management | Whether the fund tracks an index or is actively managed; its stated objective; and, for an index fund, the benchmark and methodology. |
| Theme definition | Which activities qualify as quantum-related, and whether the mandate also includes machine learning, semiconductors, quantum-enabled applications, or post-quantum security. |
| Portfolio composition | Current holdings, number of issuers, sector and company concentration, and geographic exposure. A broad-sounding theme does not by itself mean a broadly diversified portfolio. |
| Costs and trading | Current expense ratio, brokerage charges, bid-ask spreads, liquidity, and trading currency. These can vary by fund and over time; verify them in current issuer and brokerage information rather than assuming a consistent comparison. |
| Risks and instruments | Technology, market, index, geographic, and concentration risks, plus whether the fund uses direct holdings or derivatives such as options or swaps. |
Risks of investing in quantum computing ETFs
Technology and business uncertainty
Companies developing quantum-computing or machine-learning technology can face rapid technological change, product obsolescence, competition, uncertain consumer demand, and regulation. Their businesses may also depend on patents and other intellectual-property rights. These risks are described in the WisdomTree Quantum Computing Fund summary prospectus, which states: “You can lose money on your investment in the Fund.”
Index and concentration risk
An index fund is exposed to the index’s eligibility rules, weighting choices, and scheduled reconstitution. A company that remains eligible may stay in the portfolio even if its prospects weaken between reviews. Funds can also be concentrated in particular sectors, countries, currencies, or companies; the BlackRock QANT product page identifies such concentration as a risk.
Derivatives and fund-specific exposure
Fund structures and instruments can differ. Cboe describes QTUP as concentrated in the quantum-computing industry and says it may obtain exposure directly or synthetically through options and swaps. That disclosure should not be generalized to other quantum-themed ETFs. Review the specific fund’s latest prospectus for its permitted investments and risks.
No assurance of adoption or investment returns
A thematic label does not establish that quantum computing will reach a particular adoption timeline, that an underlying company will become commercially successful, or that the fund will perform well. An ETF provides exposure to the strategy it describes; it is not a forecast of the technology’s future and is not a personalized investment recommendation.
Where to verify current fund details
Fund names, holdings, fees, listings, and availability can change. Check the latest prospectus, issuer product page, index methodology where relevant, and brokerage listing before investing. The examples here illustrate distinct approaches; they are not a complete list of quantum-related ETFs.
