Quantum computing is attracting fresh investment as technology companies accelerate development timelines and governments back the sector. According to expectations cited by The Daily Upside, the first fault-tolerant quantum computers could arrive around 2028 or 2029. However, commercial adoption remains uncertain, prompting investors to look at exchange-traded funds for exposure.
The Defiance Quantum ETF (NASDAQ: QTUM) tracks the BlueStar Machine Learning and Quantum Computing Index. This fund covers companies involved in quantum computing, machine learning, computing chips, and related software. QTUM held 90 stocks and had $5.74 billion in net assets as of the report, charging an annual expense ratio of 0.40%. The portfolio is broad, with Global Unichip representing 2.33% of assets, Horizon Quantum Holdings Ltd (NASDAQ: HQ) at 1.87%, and Palantir Technologies Inc (NASDAQ: PLTR) at 1.84%. QTUM returned 36% year to date, though it experienced an 8% decline over the preceding three months.
For a more direct bet on quantum developers, the WisdomTree Quantum Computing Fund (NYSE: WQTM) allocates a larger percentage of its portfolio to companies developing the technology. The fund held approximately $346 million in assets and charged a 0.45% annual expense ratio. Its largest holdings include IonQ Inc (NYSE: IONQ) at 6.1%, Quantinuum Inc (NASDAQ: QNT) at 5.6%, Rigetti Computing Inc (NASDAQ: RGTI) at 5.2%, and D-Wave Quantum Inc (NASDAQ: QBTS) at 4.8%. IBM (NYSE: IBM), Microsoft Corp (NASDAQ: MSFT), and Amazon.com, Inc (NASDAQ: AMZN) also provided exposure to larger technology businesses.
Quantum computers are expected to eventually support drug discovery, materials science, financial modeling, and supply-chain optimization, complementing conventional CPUs and GPUs rather than replacing them entirely. QTUM offers broader exposure to the wider computing ecosystem, while WQTM tilts more heavily toward quantum specialists. Neither fund guarantees gains if the technology takes longer than expected to become commercially useful. The next test for the sector is whether progress in error correction and practical computing applications translates into repeatable customer demand and sustainable revenue.
