Comparing Quantum Computing Stocks: IonQ and Alphabet

The quantum computing sector stands at a pivotal moment as it moves from research environments into the world of commercial applications. Although a clear quantum advantage—where quantum computers would significantly outperform classical counterparts—has not yet been realized, the competition to achieve this breakthrough is creating substantial investment opportunities. Research indicates that quantum computing may generate as much as $1 trillion in economic value by 2035, promising to revolutionize sectors such as finance, defense, life sciences, and manufacturing.

Two companies leading this charge are IonQ and Alphabet, each adopting different technological strategies to advance in the quantum computing domain. As this innovative technology begins to transform areas from drug development to financial analytics, grasping their specific strategies and market positions is crucial for investors eager to benefit from this evolution.

Below, we will examine each company’s quantum platform to determine which stock may present the best opportunity in this transformative field.

Why Invest in IonQ?

IonQ’s strong position in the quantum computing space stems from three primary advantages. Firstly, its trapped-ion technology is gaining robust traction, particularly within government and defense sectors.

The company’s recent collaborations reflect this momentum, including two contracts with the U.S. Air Force Research Lab: a $54.5 million quantum computing agreement and a $21.1 million quantum networking project in partnership with Qubitekk. These deals, along with a strategic alliance with General Dynamics, highlight growing confidence in IonQ’s offerings.

Another notable advantage for IonQ is its cloud-based quantum computing services. Through major platforms such as Amazon, Microsoft, and Google, IonQ’s quantum computers are widely accessible, providing multiple revenue avenues while expanding its market presence. This model, termed quantum-computing-as-a-service (QCaaS), allows customers to explore quantum applications without needing substantial upfront investments.

However, IonQ is currently operating with significant losses as it prioritizes technological advancements over immediate profitability. In its most recent report, IonQ indicated a net loss of $129.6 million for the first nine months of 2024, with an accumulated deficit of $481.7 million. While these losses are concerning, they reflect aggressive investments aimed at increasing qubit numbers and improving fidelity—both critical elements to achieving a broader quantum advantage.

The Case for Alphabet

In contrast, Alphabet’s focus on quantum computing showcases the strength of its deep technical expertise and extensive resources. The company’s latest quantum processor, Willow, has demonstrated impressive advancements, particularly in error correction as it scales with additional qubits—an industry-essential milestone referred to as "below threshold." This breakthrough indicates that Alphabet is making considerable progress toward practical quantum computing.

The technical milestones achieved are noteworthy. Willow completed calculations in under five minutes that would take the highest-performing supercomputers billions of years to solve. While these results presently lack commercial applications, they serve as validation of Alphabet’s approaches to error correction and quantum architecture. Furthermore, Alphabet benefits from an advanced fabrication facility in Santa Barbara, which allows comprehensive control over the complex manufacturing processes involved.

Nonetheless, Alphabet’s quantum computing initiatives are merely a fraction of its extensive technology portfolio. Recent financial results reveal strong growth in artificial intelligence (AI) and cloud services, contributing to a solid operating margin of 32% last quarter. Although quantum computing may enhance these areas in the long run, particularly within AI, it remains more of a research-oriented investment than a source of immediate revenue.

Which Stock is the Better Investment in Quantum Computing?

For investors focused on pure quantum computing exposure, IonQ seems to present a more straightforward investment option, despite its current financial losses. The growth in government contracts and valuable partnerships reflects commercial validation of its trapped-ion technology. Additionally, its cloud-based services open various paths to revenue growth as the quantum market matures.

On the other hand, Alphabet offers a more balanced investment proposition. While its advancements in quantum computing are impressive, especially concerning error correction, they are just one aspect of a diverse technology portfolio.

Investors in Alphabet gain exposure to quantum computing alongside established revenue streams from advertising, cloud services, and developments in artificial intelligence. However, those specifically seeking dedicated exposure to quantum computing may find more targeted opportunities in pure-play alternatives.
