<div id="readability-page-1">Editorial produced in partnership with Defiance ETFs · April 27, 2026<h3>Claim 55% Off TipRanks</h3>Trade QQQ with leverage April 14 — World Quantum Day — has become the quantum industry's annual marketing moment, and this year NVIDIA made sure it was the main event. The chipmaker used the date to unveil NVIDIA Ising, its first open-source family of AI models purpose-built for quantum computing, alongside an expansion of the NVQLink architecture that links GPUs to quantum processors. Shares of the publicly traded quantum pure-plays responded immediately: IonQ (IONQ) closed up roughly 20% on April 15, D-Wave Quantum (QBTS) jumped more than 22%, and Rigetti Computing (RGTI) climbed more than 13%.1 Over the broader week, the four pure-plays in the Defiance 2X Daily Long Pure Quantum ETF (QPUX) target basket — IONQ, RGTI, QBTS, and Quantum Computing Inc. (QUBT) — each saw weekly moves above 30%.2 The Defiance Quantum ETF (QTUM), which seeks to track the total return performance, before fees and expenses, of the BlueStar® Quantum Computing and Machine Learning Index, closed at $125.83 on April 16 — within pennies of a new 52-week high.3 For investors who treat quantum computing as a multi-year structural theme, the week is a useful reminder of how quickly sentiment can shift when a well-capitalized player moves. For active traders, it's a reminder that the pure-play names are capable of outsized daily moves in both directions. Defiance ETFs offers vehicles for both audiences: QTUM for diversified thematic exposure, and a trio of leveraged daily-reset ETFs — ($QPUX), ($RGTX), and ($IONX) — designed for tactical, short-horizon use. <h2>Inside Quantum Week: What NVIDIA Actually Announced</h2> NVIDIA's Ising family is the first open-source AI model suite built specifically for quantum workloads. According to NVIDIA (NVDA), the release includes two components: Ising Calibration, a vision-language model for interpreting measurements from quantum processors and recommending calibration actions, and Ising Decoding, a 3D convolutional neural network for real-time quantum error correction. NVIDIA describes Ising Decoding as delivering up to 2.5x faster performance and 3x higher accuracy than pyMatching, the current open-source industry standard for error-correction decoding.4 Early adopters listed in the launch release include Harvard, Cornell, IonQ, Infleqtion, IQM Quantum Computers, Lawrence Berkeley National Laboratory's Advanced Quantum Testbed, and Sandia National Laboratories.4 NVIDIA also updated its NVQLink QPU-to-GPU interconnect architecture, which the company now says supports 17 quantum-processor builders, five quantum control-system builders, and nine U.S. national labs.5 The practical message is a continuation of a theme that CEO Jensen Huang has pushed repeatedly since 2024: quantum computers will not replace classical supercomputers; they will be tightly coupled to them. Two other Quantum Week items reinforced the rally. IonQ was awarded a contract under DARPA's Heterogeneous Architectures for Quantum (HARQ) program on April 14, focused on photonic interconnects for networked quantum systems, and announced on the same day that it had photonically interconnected two independent trapped-ion quantum computers — a technical step toward distributed quantum computing.6 IonQ trading volume on April 15 reached roughly 85 million shares versus a three-month average near 22 million.7 <h2>QTUM: A Diversified Window Into the Quantum + AI Infrastructure Theme</h2> The Defiance Quantum ETF (QTUM) takes a different approach from the pure-play basket. QTUM seeks to track the BlueStar Quantum Computing and Machine Learning Index using a modified equal-weight methodology, holding approximately 85 securities with individual position sizes capped near 2%.8 The fund launched on September 4, 2018, carries an expense ratio of 0.40%, and held $3.77 billion in assets as of April 14, 2026.3 Morningstar assigned QTUM an Overall 5-star rating as of March 31, 2026, ranked among 221 funds in the U.S. Fund Technology category (3-year) and 199 funds (5-year).9 QTUM's top ten holdings as of April 14, 2026 illustrate the structural diversification — semiconductor equipment and memory manufacturers dominate the upper tier rather than quantum pure-plays:</div>

NVIDIA launched Ising, its first open-source AI model suite for quantum computing, during Quantum Week 2026, leading to significant stock price increases for quantum companies like IonQ and D-Wave Quantum. The Defiance Quantum ETF (QTUM) also saw a rise, closing near a 52-week high. QTUM aims to track the BlueStar Quantum Computing and Machine Learning Index, holding around 85 securities with a focus on diversified exposure rather than just pure-play quantum firms. The ETF has received a 5-star rating from Morningstar, reflecting its strong performance in the technology fund category.

- NVIDIA unveiled its Ising family of open-source AI models for quantum computing on April 14, which contributed to significant stock gains for several quantum-focused companies.  
- The Defiance Quantum ETF (QTUM), with assets exceeding $3.77 billion and a 5-star Morningstar rating, aims to track a diversified index of quantum computing and machine learning firms.  
- This rapid market response highlights the volatility in quantum-related stocks and the importance of both leveraged and diversified investment options for different trading strategies.
