Besides the ongoing artificial intelligence boom in the technology sector, investor focus is also shifting to quantum computing.
In this space, several tech giants have made progress toward the overarching goal of actualizing quantum computing, an initiative likely to spur their respective stock price growth.
Indeed, their latest breakthroughs in 2025 suggest that quantum computing may soon move from theoretical promise to commercial reality.
To this end, Finbild has identified two stocks making notable advances in quantum computing.
Alphabet (NASDAQ: GOOGL)
Google’s Quantum AI division has unveiled its most advanced chip to date, known as Willow. The processor completed a benchmark calculation in under five minutes, a task Google estimates would take a classical supercomputer an unimaginable 10²⁵ years.
Beyond raw performance, the Willow chip represents a major leap in quantum error correction, the crucial technology required to scale quantum machines into practical, fault-tolerant systems.
With Alphabet (NASDAQ: GOOGL) positioning Willow as a step toward commercially relevant quantum applications, investor enthusiasm is likely to build around Alphabet’s long-term quantum roadmap.

IonQ (NYSE: IONQ), meanwhile, is emerging as the pure-play quantum stock making some of the most visible hardware progress. In one of the sector’s largest deals to date, the company completed its acquisition of Oxford Ionics for roughly $1.1 billion.
By absorbing Oxford’s on-chip trapped-ion technology, known for high fidelity and stability, IonQ has strengthened its position in one of the industry’s most reliable qubit architectures.
The company’s accelerated roadmap aims for dramatically larger qubit counts by the end of the decade, and its growing footprint in Europe signals a broader scale-up in global deployment.

In this case, fault-tolerant quantum computers will require millions of qubits, a level neither company has achieved. Commercial use cases remain limited by error rates, cost, and scaling challenges.
Therefore, investors must weigh the sector’s vast long-term potential against uncertain timelines and high capital demands.
