Japan first quantum computer put into use.
According to news on March 27, Japan’s first domestically produced quantum computer developed by RIKEN was officially put into use.
Researchers from universities and other institutions can use this quantum computer through online cloud services.

Like the technology adopted by Google and IBM, Japan’s first quantum computer also uses a superconducting circuit with zero resistance at extremely low temperatures to prepare the basic unit of information for calculations – qubits.
The device has “2D integrated circuits” and ” Vertical wiring package” function.
The quantum computer has 64 qubits , surpassing the 27-qubit quantum computer that IBM will launch in Japan in 2021.
Yasunobu Nakamura, head of development and director of the Quantum Computer Research Center, emphasized: “The accuracy is already quite close to the world level.
We will continue to improve technology and disseminate relevant technical knowledge.”
It is understood that Fujitsu accepts the technology and knowledge provided by Riken, and plans to develop a trial machine in 2023.
In short, Japanese companies will launch a full-scale counterattack, and the competition for quantum computing dominance between China, the United States and Japan will become more intense.
What is quantum computer?
Unlike classical computers, which store information in bits that can be either 0 or 1, quantum computers use quantum bits, or qubits, which can exist in multiple states simultaneously, allowing for more complex and efficient computations.
In a quantum computer, qubits are manipulated using quantum gates, which can perform operations on multiple qubits simultaneously.
This allows quantum computers to perform certain calculations much faster than classical computers, particularly for problems that involve searching large databases or factoring large numbers.
While quantum computers hold great potential for solving complex problems, they are still in the early stages of development and are currently limited by the number of qubits that can be reliably controlled and the errors that can arise from their delicate quantum nature.
However, many researchers and companies are working to develop more powerful and reliable quantum computers, which could have a significant impact on fields such as cryptography, drug discovery, and materials science.
What are the advantages of quantum computer over regular computer?
Quantum computers have several advantages over regular computers:
-
Speed: Quantum computers can perform certain calculations much faster than classical computers. This is because qubits can exist in multiple states simultaneously, allowing for parallel processing of information.
-
Efficiency: Quantum computers can solve certain problems with fewer steps than classical computers, making them more efficient in certain tasks.
-
Security: Quantum computers have the potential to break many of the encryption techniques currently used to secure data, but they also have the potential to create new, unbreakable encryption techniques.
-
Simulation: Quantum computers can simulate quantum systems much more accurately than classical computers, which is important in fields such as materials science and drug discovery.
-
Optimization: Quantum computers can optimize complex systems much more efficiently than classical computers, which is important in fields such as finance and logistics.
However, it’s worth noting that quantum computers are still in the early stages of development and are currently limited by the number of qubits that can be reliably controlled and the errors that can arise from their delicate quantum nature.
