Quantum computers, which are being developed for practical use in the future, are subject to the possibility of errors occurring in every step from setting the initial state of the qubit to reading the output at the time of article creation, greatly limiting what can be done. I am. On April 3, 2024, Microsoft and quantum computing company

Quantum computers basically use qubits to store and process information. However, physical qubits are prone to errors due to noise, so Traditional quantum computers are severely limited in their usefulness and practicality. To reduce these errors, advanced techniques had to be used to combine multiple physical qubits into reliable virtual qubits called 'logical qubits.'

When you enable logical qubits, you can increase the number of physical qubits to create powerful quantum computers that can perform longer and more complex calculations.

Now, by combining Microsoft's qubit virtualization system and Quantinuum's H2 ion trap qubit processor with a unique quantum charge-coupled device architecture, 30 physical qubits can be reduced to four highly reliable logical qubits. I was able to successfully combine them. Combining multiple physical qubits into one logical qubit allows systems to be protected from errors. According to Microsoft, the new logical qubit was able to run 14,000 independent instances without a single error.

Furthermore, it has been revealed that these logical qubits only cause an error once per 100,000 executions, reducing the error rate to 1/800 of the conventional method using only physical qubits. that's right. According to Jennifer Strubley of Quantinuum, this achievement of ``reducing errors from physical qubits by 800 times'' is the lowest error rate ever.

Microsoft commented on this result, saying, ``Enabling the noise canceling feature of headphones while listening to music while eliminating most of the environmental noise is similar to applying a qubit virtualization system.'' 'Improving error rates is similar to the silence achieved with high-quality noise-canceling headphones.'

On the other hand, the research team revealed that this logical qubit is still in the development stage, saying, ``In order to surpass conventional quantum computers, we need to correct individual circuit errors and create quantum entanglement between at least two logical qubits.'' 'We need to further expand the difference in error rates between logical and physical qubits, as well as the ability to

Still, Microsoft CEO Satya Nadella said, 'This is an extremely exciting milestone on the path to realizing the scientific and commercial advances that come from reliable quantum computing.' Leave a comment of praise.

'These results are a historic achievement and a great reflection of how our collaboration with Microsoft continues to push the boundaries of the quantum ecosystem,' said Ilyas Khan, founder and chief product officer at Quantinnum. With Microsoft's cutting-edge error correction capabilities, coupled with the world's most powerful quantum computers and a fully integrated approach, we are very excited about the potential for further advances in quantum applications, especially at large scale. We can't wait to see how our customers and partners benefit from Quantinnum's solutions as we move to advanced quantum processors.'
