Japan Unveils First Full-Stack Quantum Computer at Room Temperature
Confirmed
In Short: Professor Ohmori, from the Institute for Molecular Science (IMS) at Japan's National Institutes of Natural Sciences, announced the development of Japan's first full-stack quantum computer, Shunkai, which can perform quantum calculations at room temperature.
Professor Ohmori, from the Institute for Molecular Science (IMS) at Japan's National Institutes of Natural Sciences, announced the development of Japan's first full-stack quantum computer, Shunkai, which can perform quantum calculations at room temperature.
Shunkai was developed in collaboration with Hitachi and uses a quantum processing unit (QPU) from Infleqtion, a US-based tech company.
The machine's operation is significant as it represents a step forward in quantum computing, which traditionally faces challenges due to the need for extremely low temperatures to maintain quantum coherence.
Quantum computers use qubits, which can exist in multiple states simultaneously, unlike classical bits that are strictly 0 or 1. This property allows quantum computers to solve certain problems much faster than classical computers.
In a separate development, researchers at Kyushu University and Kobe University achieved quantum coherence at room temperature by embedding a chromophore in a metal-organic framework (MOF), a nanoporous crystalline material.
The researchers observed quantum coherence in a system with four electron spins, a first for molecular systems at room temperature.
Quantum sensing technology, which leverages the sensitivity of entangled states to environmental noise, is expected to enable higher resolution and sensitivity in sensing applications.
Shunkai's potential applications include error-correction technologies and practical industrial, academic, and governmental uses.
Professor Ohmori noted, “We expect that the external use of our full-stack machine Shunkai would lead to ripple effects on various fields in industry, academia, and government around the world.”

- In a study published in Science Advances, a group of researchers led by Associate Professor Nobuhiro Yanai from Kyushu University’s Faculty of Engineering, in collaboration with Associate Professor Kiyoshi Miyata from Kyushu University and Professor Yasuhiro Kobori of Kobe University, reports that they have achieved quantum coherence at room temperature: the ability of a quantum system to maintain a well-defined state over time without getting affected by surrounding disturbances This breakthrough was made possible by embedding a chromophore, a dye molecule that absorbs light and emits color, in a metal-organic framework, or MOF, a nanoporous crystalline material composed of metal ions and organic ligands.
- Notably, chromophores can be used to excite electrons with desirable electron spins at room temperatures through a process called singlet fission.
- This is opening a new approach to quantum computation & technology So, after all the hype and scare pumped into quantum computing recently, it turns out it’s just another cold fusion: always just ten years away.
- However, so far, it has been challenging to entangle four electrons and make them respond to external molecules, that is, achieve quantum sensing using a nanoporous MOF.
- While the coherence was observed only for nanoseconds, the findings will pave the way for designing materials for the generation of multiple qubits at room temperatures.
- Various systems can be employed to implement qubits, with one approach being the utilization of intrinsic spin—a quantum property related to a particle’s magnetic moment—of an electron.
- Breakthroughs, discoveries, and DIY tips sent six days a week.
- The Martian surface is a practically airless vacuum, constantly bombarded with radiation, and regularly reaches temperatures as low as -81 degrees Fahrenheit.
- Sonera previously announced that it had developed "breakthrough sensing technology" that "non-invasively measures magnetic fields" generated by the brain and body.
- "This proprietary technology holds the key to making brain activity as easy to measure as heart rate, temperature, and other physiological signals," said Sonera, in a 2023 press release.
