3 ETFs That Own the Quantum Compute Transition

The quantum computing trade has shifted from speculation to an investable theme with identifiable catalysts. On May 21, 2026, the Department of Commerce allocated roughly $2 billion in CHIPS Act letters of intent to nine quantum companies, including $100 million each for D-Wave, Rigetti, Quantinuum, PsiQuantum, Atom Computing, and Infleqtion. That federal capital sits alongside IBM's error-correction milestones and Google's Willow chip benchmarks, moving the timeline question from "will quantum work" to "which modality scales first." For investors, the question is not whether to get exposure – it is which vehicle captures the transition without taking the wrong side of volatility.

Three exchange-traded funds dominate the discussion, each taking a distinct approach. Defiance Quantum ETF (QTUM) holds pure-play qubit makers in an equal-weighted basket. ARK Autonomous Technology & Robotics ETF (ARKQ) layers active management over quantum-adjacent semiconductors and control electronics. Global X Robotics & Artificial Intelligence ETF (BOTZ) provides picks-and-shovels exposure through industrial automation and AI hardware. The performance gap tells the real story: QTUM is up 45% year-to-date and 86% over 12 months; ARKQ returned 25% YTD and 76% in the past year; BOTZ shows 11% YTD and 30% one-year.

The Catalyst: Federal Capital and Milestones That Broke the Narrative

The $2 billion in CHIPS Act letters of intent is not theoretical. It funds actual fabrication of qubit hardware, cryogenic enclosures, and classical control electronics at nine companies, many of which are held directly in QTUM. IBM's progress on error-correction and Google's Willow benchmarks have shifted the conversation from speculation to commercialization timelines. For ETF investors, the mechanism is simple: when a milestone hits, the pure-play names move first and hardest. QTUM rose roughly 23% over the past month alone, tracking the funding announcements and milestone news.

The market read is not that quantum is risk-free. The risk-reward now has a catalyst calendar. This is no longer a thesis that requires faith in a 10-year horizon. It is a thesis that responds to concrete government and corporate spending.

QTUM: The Only Pure-Play Quantum Basket

QTUM tracks the BlueStar Quantum Computing and Machine Learning Index and is the only ETF on this list designed around the quantum thesis explicitly. It holds listed pure-plays – IonQ, Rigetti, D-Wave, Quantum Computing Inc. – plus larger platform owners with quantum research divisions: IBM, Alphabet, and Honeywell. The expense ratio is 0.40%, competitive for a thematic fund this narrow.

Equal-Weighting and the Volatility Tradeoff

The portfolio is roughly equal-weighted, which matters more than it sounds. A market-cap weighting would let IBM and Alphabet dominate, diluting exposure to the small qubit makers that most investors want. Equal weighting keeps IonQ and Rigetti meaningful contributors to returns. The tradeoff is volatility: when those names rally on a CHIPS headline, QTUM captures it directly. When they drop 30% on a missed milestone, the fund feels it sharply.

For traders tracking individual holdings, IBM carries an Alpha Score of 50, AMD scores 59, and NVIDIA leads the trio at 73 with a current price of $211.14, down 1.45% on the day. Those scores give a quick reference point for the health of the larger positions within the ETF basket.

ARKQ: Active Management with Quantum Adjacencies

ARKQ is actively managed with a mandate to invest at least 80% in autonomous technology and robotics companies. Net assets stand at $2.1 billion and the expense ratio is 0.75%, the cost of conviction-driven allocation. The fund does not hold qubit makers directly. Instead, it owns the classical compute and testing layer that every quantum system requires.

Concentration Risk in the Quantum-Adjacent Play

Tesla anchors the fund at about 10%, followed by Teradyne at roughly 7%, Advanced Micro Devices at about 8%, Kratos Defense at 5%, and Palantir near 3%. The semiconductor and testing names are the quantum-adjacent exposure: Teradyne builds the test equipment, AMD supplies classical processors, and Palantir handles the data workflows that quantum simulations plug into. The problem is that 10 positions account for more than half of the fund, and a drawdown in Tesla moves the entire portfolio.

ARKQ returned 25% YTD and 76% over the past year. It is the right vehicle for investors who want active conviction with quantum-adjacent positioning. Those investors must accept that the fund’s performance will often diverge from news about IonQ or Rigetti.

BOTZ: Infrastructure for Any Modality

BOTZ manages about $3.44 billion in net assets, making it the largest of the three. It concentrates in industrial robotics, machine vision, and AI compute hardware. The case for including it in a quantum-themed portfolio rests on a single mechanism: every quantum system shipped requires a stack of classical infrastructure – precision manufacturing, cryogenic enclosures, and test equipment – and that stack is exactly what BOTZ owns.

Japanese Automation and the Picks-and-Shovels Bet

Keyence sits at roughly 9% of net assets, ABB at about 9%, FANUC near 9%, and NVIDIA around 8%. The industrial automation names, mostly Japanese and European, supply the equipment that fabricates qubit chips, photonic packages, and cryogenic enclosures. The fund holds 51 positions across about a dozen automation verticals, with heavy weighting toward Japan. Year to date, BOTZ is up 11%, with a one-year return of 30%.

The lag versus QTUM reflects the tradeoff: less direct quantum upside with less drawdown risk when a single-qubit company misses a milestone. The five-year return of 19% is a reminder that broad automation exposure does not always compound as much as pure thematic plays during a hype cycle.

Comparing Returns, Risk, and the Right Fit

The metrics confirm the narrative. QTUM delivers the highest raw returns with the highest volatility. ARKQ offers active management with a concentrated portfolio. BOTZ provides diversification across the compute infrastructure that benefits regardless of which qubit modality wins.

Practical rule for allocation

Investors who want direct exposure to the qubit commercialization trade and can stomach the volatility should lean toward QTUM. Investors who prefer active management and are comfortable with a portfolio that touches quantum through semiconductors and defense should consider ARKQ, though the Tesla weighting means performance will often diverge from quantum news. Investors who want a structural holding that benefits no matter how the timeline plays out should use BOTZ.

A blended approach weights toward QTUM for thematic intensity and toward BOTZ for diversification, with ARKQ filling a conviction-sized slot for those who believe in Cathie Wood’s active process. The commercialization of quantum computing is no longer a question – it is a set of positions to be managed.

For additional context on the individual holdings, the IBM stock page shows an Alpha Score of 50, the AMD stock page shows a 59, and the NVDA stock page shows a 73 at $211.14. Broader stock market analysis can help frame the sector rotation around the quantum theme.
