Quantum Computing Takes Center Stage in 2025 Tech Trends

Emerge’s 2025 Tech Trend of the Year: Quantum Computing Stopped Being Background Noise

For years, one of the quiet assumptions underpinning modern cryptography was that quantum computers were still too noisy and fragile to pose a practical threat. In 2025, that comfort weakened, as advances in hardware, software, and funding made quantum progress harder to dismiss as purely experimental.

Emerge framed the shift as a key 2025 tech trend, pointing to a year marked by frequent milestones and a growing sense that quantum computing is moving from isolated lab systems toward infrastructure that can be operated, integrated, and funded at scale.

A surge of late-stage funding and partnerships reshaped the global quantum industry in 2025, with capital concentrating around specific hardware approaches, cloud software platforms, and security technologies positioned for nearer-term deployment. Public-market interest also increased: pure-play quantum companies were widely discussed in 2025, and shares of IonQ, Rigetti Computing, and D-Wave Quantum were cited as outperforming the S&P 500 during the year. Separately, asset managers and hedge funds were reported as buyers of Rigetti Computing stock, even as the company disclosed heavy losses.

On the technical side, 2025 brought results aimed directly at the “too noisy to matter” narrative. Researchers demonstrated that a quantum system can become more stable as it scales, rather than more fragile—a result described as marking the end of the “Noisy Intermediate-Scale Quantum” (NISQ) era and the start of a new phase focused on greater stability and reliability.

Other developments reinforced the idea that quantum is becoming operational technology rather than a standalone curiosity. NVIDIA launched NVQLink, described as a platform designed to connect quantum processors into classical high-performance computing (HPC) environments and AI workflows. Hyperscale cloud providers were also active: AWS, Microsoft Azure, and Google Cloud were all described as running credible quantum efforts, while IBM was cited as scaling aggressively and Quantinuum as linking AI and quantum approaches.

Research teams also focused on making quantum systems easier to use and more practical to run. In April, Stephanie Wehner and colleagues at Delft University of Technology introduced QNodeOS, an operating system intended to improve access to quantum computing without requiring deep quantum specialization. In June, Chalmers engineers reported a pulse-driven qubit amplifier said to be ten times more efficient while staying cool and protecting quantum states—work connected to reducing noise and supporting larger systems.

Hardware progress was not limited to one region or architecture. Researchers from Moscow State University reported a 72-qubit quantum computer prototype based on single rubidium atoms, described as Russia’s third prototype to surpass the 70-qubit threshold. IonQ, meanwhile, continued to highlight the properties of its approach: by using naturally stable atoms isolated in a vacuum, its qubits are less susceptible to environmental noise and decoherence, a characteristic tied to fewer errors and more reliable results.

Beyond core computing, enabling technologies were also emphasized. New photonic and microwave-control techniques—using microwave-frequency vibrations to precisely manipulate laser light and generate stable new laser frequencies—were described as important not only for quantum computing, but also for quantum sensing and quantum networking.

Another theme throughout the year was convergence: quantum systems increasingly framed as part of hybrid computing stacks rather than separate machines. The expectation described for HPC centers was a gradual integration of photonic technologies into existing simulation workflows to target slow, power-hungry computational kernels, improving speed and energy efficiency. Cloud AI platforms were also described as partners, particularly for molecular and materials modeling where quantum methods can complement classical tools, with software companies expanding from pure quantum algorithms into workflow automation, error mitigation, and GPU-accelerated quantum simulation.

For cryptography and the crypto ecosystem, the significance is not that quantum computers have suddenly broken widely used encryption, but that 2025 produced enough concrete progress—along with serious investment and integration into mainstream compute environments—to reduce confidence in the long-standing assumption that quantum risk is safely distant.
