Fujitsu Asia Pte Ltd scores win at Singapore Business Review International Business Awards 2026

Fujitsu Asia Pte Ltd emerged as the recipient of the Technology accolade at the Singapore Business Review International Business Awards 2026. The award honours the company’s recently introduced AI Computing Broker (ACB) services, a workload broker technology that effectively utilises the available GPUs for AI workloads together with its on-going trials in a proof-of-concept project with a leading university in Singapore.

Decoding the Future - Quantum Computing Explained (Without the Confusion)

Quantum computing often feels like something straight out of a sci-fi movie - intimidating, complex, and full of jargon like “superposition” and “entanglement” - but we are on the cusp of a major tech disruption that will redefine everything from national security and encryption to how we discover new medicines. Join Mahesh Krishnan, CTO, Fujitsu Australia Limited, and Rose Ahlefeldt, Quantum Physicist, Australian National University, as they decode the future of quantum computing with a clear explanation of quantum terminologies, key concepts and practical applications that will benefit businesses.

Waves before the breakthrough: navigating Australia's quantum horizon

Laura Entwistle, Consulting Partner at Uvance Wayfinders and Mahesh Krishnan, CTO at Fujitsu, examine Australia’s quantum readiness, emerging risks, strategic opportunities, and what government and industry leaders should prioritise now.

Inside Superconducting Quantum Computer

Signals from the external control unit are attenuated and sent to the superconducting quantum chip, which is kept at an extremely low temperature. After the computation, the signals that represent the measured quantum states are progressively amplified and returned to the analysis unit.

The computers we use today have become more powerful through the miniaturisation of superconductors

As classical computers reach their limits, quantum computers offer a new way forward by using qubits that can represent multiple states at once instead of just 0 or 1. This allows computing power to grow extremely fast as more qubits are added. By combining quantum computers with classical supercomputers, this technology could help solve problems that were previously impossible, improve AI, and tackle major challenges in areas like healthcare, finance, and manufacturing while supporting broader digital transformation across society.

Leading the business with quantum computers in 2030

Quantum computing is a pivotal technology poised to drive significant advancements and transformative changes across society and business. By 2030, as its computing power scales dramatically, Fujitsu believes that a significant disparity will emerge between enterprises leveraging quantum technology and everyone else. Fujitsu is committed to supporting customers in becoming early adopters of quantum computing to maximize the competitive benefits of this transformative era.

Solving complex social challenges with quantum technology

Quantum computers are well suited to rapidly process complex problems that push the limits of conventional computing. This unique ability to perform computations previously deemed intractable will accelerate the creation of new value,  and enable groundbreaking discoveries and problem-solving across numerous fields, including materials science, drug discovery, and financial forecasting.

Fujitsu's quantum computing R & D strategy

Fujitsu, in collaboration with leading research institutes worldwide, promotes R & D across all areas of quantum technology - from hardware (such as quantum devices, integration, and quantum state control) to foundational software (quantum platform and quantum software), as well as practical quantum applications, with the goal of progressing towards widespread commercial use of quantum computers.

World-leading quantum computing technology

Fujitsu is dedicated to leading global R&D in quantum technology, and accelerating its real-world adoption.

World-leading 256-qubit superconducting quantum computer

In April 2025, Fujitsu, in joint development with RIKEN, developed a world-leading 256-qubit superconducting quantum computer. It has been available to companies and research institutions since the first quarter of fiscal 2025.

1,000 qubits computer scheduled for 2026 installation

Fujitsu is currently developing a 1,000-qubit superconducting quantum computer, scheduled to be installed in a new building at the Fujitsu Technology Park and launched in 2026.

Diamond spin quantum computer

Fujitsu is also exploring optional alternatives to superconducting quantum systems. Comparatively, the Diamond spin approach offers superior scalability through optical interconnects. In March 2025, we achieved the world's first high-precision quantum gate operation with an error probability below 0.1%, a crucial step toward large-scale quantum computing.
