Japan's TOYO Corporation has installed a full-stack quantum computer, IQM Spark, capable of operating at room temperature, marking a significant step in quantum computing. The system, which will be operational in early 2027, is expected to operate with approximately 50 qubits, with plans to scale up to around 500 qubits as development progresses.

The Spark system will be installed at TOYO’s R&D center in Kiba, Tokyo, and will serve as a testbed for evaluating and verifying components and related technologies used in superconducting quantum computers under real operating conditions. This marks a pivotal moment for Japan’s quantum ambitions as the country aims to advance scalable quantum computing.

The new benchmark, QUOPS or Quantum Universal Operations Performance System, aims to provide a standardized way to assess the performance of different quantum computers. This benchmark is particularly important because there are many ways to build a quantum computer, making it challenging to compare their performance.

Associate Professor Nobuhiro Yanai from Kyushu University and his team have achieved quantum coherence at room temperature by embedding a chromophore in a metal-organic framework (MOF). This breakthrough allows for the generation of multiple qubits at room temperatures, a critical advancement for quantum computing and sensing technologies.

The chromophore, a dye molecule that absorbs light and emits color, was introduced in a UiO-type MOF to suppress molecular motion and achieve room-temperature quantum coherence. This is opening a new approach to quantum computation and technology, as it enables the creation of qubits that can exist in a combination of states and be 'entangled'.

While quantum coherence was observed only for nanoseconds, the findings will pave the way for designing materials for the generation of multiple qubits at room temperatures. This is a significant step towards practical quantum computing, as it addresses the challenge of maintaining quantum information at room temperature.

The Spark system will be made available to external users to support the development of applications and advance quantum error correction research across academia and industry. This approach aligns with TOYO’s commitment to broadening access to quantum computing and contributing to the real-world adoption of quantum technologies in Japan.

According to Grand View Horizon, Japan’s quantum computing market generated a revenue of US$ 84.7 million in 2025, and is expected to reach US$ 555.5 million by 2033. This growth underscores the increasing demand for on-premises quantum computers and the importance of initiatives like the Spark system in driving the adoption of quantum technologies.

What this adds

The QUOPS benchmark is designed to be a flagship benchmark for the field, giving a summary performance of the computational power of different quantum computers and allowing us to track progress towards useful quantum computing.

The chromophore-based approach to achieving quantum coherence at room temperature is a significant advancement, as it typically requires liquid nitrogen-level temperatures to maintain quantum superposition and entanglement.

The Spark system's full-stack approach combines high-performance hardware with proprietary software, offering programmability, scalability, and fidelity control that next-generation systems demand.
