A Rigetti quantum computer was showcased at Nvidia’s booth during the Nvidia GTC (GPU Technology Conference) in Washington, DC, on Wednesday, October 29, 2025.
The burgeoning field of quantum computing saw significant gains this week, with quantum stocks rallying sharply. This surge is largely attributed to renewed enthusiasm following Nvidia’s introduction of new open-source artificial intelligence models designed to accelerate the development of this transformative computing technology.
Since the beginning of the week, shares of IonQ have seen a remarkable surge of approximately 50%, mirroring the performance of D-Wave Quantum. Both Quantum Computing Inc. and Rigetti Computing have also experienced substantial growth, with their respective stocks climbing more than 20% each.
This impressive rally follows Nvidia’s unveiling of “Ising,” a novel suite of open-source AI models aimed at expediting the practical implementation of quantum computing. Nvidia CEO Jensen Huang emphasized the critical role of AI in making quantum computing a reality, stating, “AI is essential to making quantum computing practical. With Ising, AI becomes the control plane — the operating system of quantum machines — transforming fragile qubits to scalable and reliable quantum-GPU systems.”
Nvidia elaborated in a press release that Ising offers high-performance, scalable AI tools specifically for quantum error correction and calibration. These two areas represent some of the most formidable challenges in the construction of hybrid quantum-classical systems. The company strategically named Ising after a renowned mathematical model, underscoring the scientific underpinnings of their innovation.
The announcement coincided with “World Quantum Day,” an annual observance established in 2021 to promote public understanding of quantum technology. April 14th was chosen due to its representation of the Planck constant, a fundamental value in quantum physics.
This wave of positive momentum for Nvidia also extends to its stock performance. Tuesday marked Nvidia’s longest consecutive winning streak since 2023, with its shares appreciating by 18% over a ten-day period.
Proponents of quantum computing herald it as a potentially revolutionary technology capable of dramatically accelerating fields such as drug discovery and solving complex problems that remain intractable for even the most powerful classical computers. Recognizing this potential, governments and major technology corporations are making substantial investments to advance quantum computing capabilities.
Over the past few years, leading hyperscalers including Microsoft, Alphabet, and Amazon have announced the development of specialized chips designed to power these future-oriented quantum systems. IBM is also actively pursuing the development of its first quantum computer, with a target completion date of 2029.
However, the quantum computing market, while growing, remains relatively nascent. The largest publicly traded companies in this sector collectively represent approximately $31 billion in market value prior to Thursday’s trading session. The speculative nature of the industry means that the sector is susceptible to significant price volatility, and many stocks have experienced declines year-to-date. For instance, D-Wave and Rigetti have seen their stock prices fall by 20% and 15%, respectively.
IonQ also made notable headlines this week. The Maryland-based company announced a significant technical achievement: the successful linking of two remote quantum computers, a development they described as a “foundational technical milestone” for networked quantum systems utilizing entanglement. In parallel, the company secured a contract with the Defense Advanced Research Projects Agency (DARPA), further solidifying its position in the quantum research landscape.
The ongoing advancements in quantum computing, coupled with significant investments from both public and private sectors, signal a critical juncture for this technology. Nvidia’s strategic move with its Ising AI models underscores a growing understanding that sophisticated AI is not merely an adjunct but a fundamental enabler for realizing the full potential of quantum computation. As the field matures, the interplay between AI and quantum hardware will be a key determinant of progress, potentially unlocking solutions to some of humanity’s most pressing challenges.
