2 Japan’s First Quantum Computer: 3 Superconducting Quantum Computer
A Fully Domestic Quantum Computer: From Osaka to the World
Center for Quantum Information and Quantum Biology (QIQB), The University of Osaka
Quantum computers are a new type of computer that uses the properties of quantum superposition and entanglement to perform calculations. Using quantum bits (qubits) that can exist in a superposition of 0 and 1, they interfere with each other like waves, allowing for various possibilities. The results are observed to derive answers. This mechanism makes it possible to complete tasks that are impossible for conventional computers, such as factoring large numbers, calculating the behavior of complex molecules, and elucidating photosynthesis and black holes. As a result, technological innovations are advancing rapidly all over the world.
In this section, you can use a tablet to try programming on a domestically developed quantum computer, which was developed through a collaboration between The University of Osaka, and various institutions and companies. There are also displays of models and games showcasing components, materials, and mechanisms developed by domestic manufacturers. Come and experience the future of computing firsthand!

“A”, Japan’s First Quantum Computer
RIKEN Center for Quantum Computing (RQC)
In March 2023, RIKEN unveiled “A”, Japan’s first domestically produced superconducting quantum computer. Later the same year, a second unit was introduced at the RIKEN RQC-Fujitsu Collaboration Center followed by a third one at The University of Osaka. This year came to be known as the first year of domestically produced quantum computers.
Here, you can experience a quantum computer recreated using XR (cross-reality) technology that blends virtual and real worlds, based on the 3D design diagrams of “A”. Take a close-up look at the quantum chip, often referred to as the “brain” of the quantum computer, which was actually developed at RIKEN.

This XR (extended reality) experience enables you to explore a superconducting quantum computer. Meticulously reconstructed from actual blueprints, the large-scale device can be taken apart by hand, layer by layer. As you remove the intricate wiring, components, and cooling systems, you eventually uncover a tiny chip at its center forming the heart of quantum computation. By picking up the chip and examining it at close range, you gain a tangible sense of the precision underlying this cutting-edge technology. A charming cat character explains how the quantum computer works, making the complex science accessible to all audiences.

Chandelier: The Form of a Superconducting Quantum Computer
Fujitsu Limited
When you remove the large cylinder of a quantum computer, a gold freezer appears. At the very bottom of this freezer lies a quantum bit integrated circuit cooled to nearly absolute zero (colder than the temperature of the universe), which serves as the brain of the quantum computer. Referred to as a “chandelier,” the freezer has unique appearance with countless cables leading to the chip in order to manipulate the quantum bits.
In this exhibition, you can view a full-scale model of the second unit developed at the RIKEN RQC – FUJITSU Collaboration Center. Quantum computers are devices that attempt to unlock the mysteries of nature by directly manipulating the quantum properties that govern the natural world. Just as nature is beautiful, quantum computers possess a unique charm.
