Google continues to lead with bold milestones. In 2019, its Sycamore processor made headlines by achieving quantum supremacy. More recently, in December 2024, Google introduced Willow—a quantum chip capable of performing a computation in under five minutes that would take even the most powerful classical supercomputers an estimated 10 septillion years. This quantum leap, so to speak, highlights the dramatic computational advantages possible soon.

Microsoft is pursuing a different path, centered on topological qubits. Microsoft unveiled the Majorana 1 chip in February 2025, which is the first quantum processor powered by topological qubits. This approach promises improved stability and lower error rates, paving the way for more scalable and stable quantum systems. Through its Azure Quantum platform, Microsoft offers developers and enterprises a suite of tools, including the Q# language, to explore algorithm design and integrate quantum functions into classical workflows.

Startups are also vital to the quantum ecosystem. They are delivering high-fidelity quantum operations through trapped ion technology and pioneering photonic quantum systems that can operate at room temperature—an approach that may simplify large-scale deployment. Companies specializing in quantum annealing are already providing optimization capabilities to solve business-critical problems in logistics, machine learning, and material simulation. A leading quantum computing company has announced plans to build its first full-scale, fault-tolerant quantum computer in Queensland which also includes a $90 million investment to support technological development and talent acquisition.

Recent developments also include hybrid quantum-classical computing frameworks, advances in cryogenic control systems that extend qubit coherence, and quantum networking experiments that span hundreds of kilometers. These breakthroughs demonstrate that progress is not only about building powerful machines but also about building practical, scalable platforms for enterprise adoption.

Recent breakthroughs in quantum computing

The quantum computing landscape has seen remarkable progress in recent years, with breakthroughs across algorithms, hardware and applications.

Quantum algorithms continue to unlock new possibilities. Shor’s algorithm, which can factorize large numbers exponentially faster than classical methods, directly threatens existing cryptographic systems. Grover’s algorithm enhances search efficiency, offering potential applications in database management and cybersecurity.

One of the most exciting advancements in quantum computing is the development of quantum networks, which could create a fully functional quantum internet. In 2023, researchers from the Delft University of Technology in the Netherlands successfully demonstrated quantum entanglement between three nodes in a quantum network, a crucial step toward building scalable quantum communication systems. Unlike traditional networks, a quantum internet would enable ultra-secure communication by leveraging entanglement-based encryption, making it virtually impossible to intercept or tamper with transmitted data. This breakthrough has profound implications for cybersecurity, enabling unhackable communication for governments, financial institutions and enterprises handling sensitive data. 

In healthcare, quantum systems are already showcasing their transformative potential. For example, researchers at biotech firms are leveraging quantum-inspired computing to accelerate the identification of biomarkers for neurodegenerative diseases.

Challenges in scaling quantum computing

Despite these advancements, significant hurdles remain. One of the most pressing challenges is error correction. Qubits are inherently unstable and susceptible to environmental noise, leading to computational errors. While researchers have developed methods to combine multiple physical qubits into a single logical qubit, fully fault-tolerant quantum systems are still years away.

Another obstacle is scalability. Current quantum systems operate with hundreds of qubits, but practical applications require systems with thousands or even millions of qubits. Addressing this challenge involves improving qubit fidelity and developing robust cooling systems and error-correction protocols.

Additionally, the quantum industry faces a talent shortage. The highly specialized nature of quantum mechanics, hardware engineering and software development means that demand for skilled professionals far outstrips supply. Governments and companies are addressing this gap by investing in education initiatives, such as the U.S. Quantum Workforce Development Plan, which aims to cultivate a new generation of quantum experts.
