Quantum computing is an innovative technology with the potential to solve the most complex problems facing humanity. At its heart is IonQ, a leader in this field, developing trapped-ion quantum computers. IonQ has shown remarkable achievements in both technological development and commercial expansion in recent years, accelerating the advent of the quantum era. In 2025, we will take a closer look at IonQ's technology status and future prospects.
IonQ focuses on trapped-ion technology, which utilizes individual atoms as qubits. It precisely fixes ionized Ytterbium (Yb+) atoms with electromagnetic fields and manipulates the qubit states using lasers to implement entanglement. Recently, research on Barium (Ba+) ions is also actively underway to improve control and readout efficiency. In particular, on October 21, 2025, it achieved a world record by achieving 99.99% 2-qubit gate fidelity through its self-developed Electronic Qubit Control (EQC) technology. This significantly reduces the overhead required for quantum error correction, becoming a major milestone in the development of large-scale quantum systems. EQC technology controls qubits using precision electrons instead of lasers and can utilize existing semiconductor manufacturing processes, contributing to increased scalability, stability, and cost-effectiveness.
In September 2025, IonQ presented a new benchmark for quantum computing performance by achieving #AQ 64 (Algorithm Qubits) on its Tempo system. This is a result that is 3 months ahead of schedule, meaning that the Tempo system can consider more than 1800 quintillion possibilities, and it can be used to solve complex real-world problems such as energy, new drug development, engineering simulation, supply chain optimization, and fraud detection. The increase in the #AQ value means that the useful computational space for executing quantum algorithms has doubled, showing that IonQ can provide a computational space 36 quintillion times more powerful than IBM's current quantum system.
IonQ is also focusing on increasing the accessibility of quantum computing. Through the IonQ Quantum Cloud platform, users can develop and experiment with quantum algorithms by connecting to IonQ's quantum processor (QPU) and simulators. This platform is compatible with major quantum software development kits (SDKs) and provides on-demand or QPU time reservation methods. In particular, since June 2021, IonQ's quantum computers have also been accessible through the Google Cloud Marketplace, allowing more developers, researchers, and companies to easily utilize quantum technology. In April 2025, it also agreed to collaborate with G-QuAT (Global Research and Development Center for Business by Quantum-AI Technology) in Japan to provide cloud-based access to Forte-class quantum systems.
IonQ aims to lead the future quantum computing market through an aggressive technology roadmap. In 2025, it plans to introduce a system with approximately 100 physical ion trap qubits (development prototype), and by 2027, it plans to implement approximately 10,000 physical qubits on a single chip. In 2028, it aims for a system with a total of 20,000 physical qubits through two chips connected by photonic interconnects, which corresponds to approximately 1,600 error-corrected logical qubits. Ultimately, by 2030, it plans to achieve millions of physical qubits and 40,000 to 80,000 logical qubits, accelerating innovation in new drug development, materials science, financial modeling, logistics, cybersecurity, and national defense.
IonQ is pursuing various strategic partnerships and acquisitions to accelerate its technology roadmap and strengthen its market position. In 2025, it acquired Oxford Ionics to secure chip-integrated ion trap technology and acquired Lightsynq to strengthen photonic interconnect technology for faster connections between quantum processing units. In addition, it is collaborating with Emergence Quantum of Australia to jointly develop next-generation quantum hardware and is contributing to the development of pharmaceutical research by building a quantum-accelerated chemical calculation workflow with AstraZeneca, AWS, and NVIDIA. In September 2025, it signed an MOU with the U.S. Department of Energy (DOE) for the development of quantum secure communication and space quantum technology, and in October, it participated as a founding member of the Q-Alliance in Italy to build a world-class quantum computing hub in Lombardy. These collaborations show that IonQ's quantum technology can be applied to a wide range of fields, including energy grid optimization, autonomous vehicle object detection, and artificial intelligence.
IonQ is solidifying its position as a leader in the quantum computing field through its unique ion trap technology, continuous performance improvements, an aggressive roadmap, and extensive partnerships. As of 2025, the record-breaking achievements of #AQ 64 and 99.99% 2-qubit gate fidelity demonstrate the rapid progress of IonQ's technology. The expansion of cloud access and the grand goal of achieving millions of qubits by 2030 show that the day when quantum computing has an innovative impact on real industries and society is not far off. IonQ's quantum technology will open unprecedented possibilities, from new drug development to finance, national defense, and space technology. We look forward to the next chapter of the quantum revolution led by IonQ.
