Microsoft and Quantinuum demonstrate the most reliable logical qubits on record with an error rate 800x better than physical qubits - The Official Microsoft Blog

Yesterday marked a breakthrough in quantum computing: Microsoft and Quantinuum showcased the most dependable logical qubits ever documented.

These logical qubits have an error rate 800x better than physical qubits.

Researchers have achieved a significant improvement in error correction, allowing them to move from basic ("Foundational") to more robust ("Resilient") quantum computers.

???? Microsoft’s announcement states: "we ran more than 14,000 individual experiments without a single error. Furthermore, we demonstrated more reliable quantum computation by performing error diagnostics and corrections on logical qubits without destroying them."

???? This milestone represents a pivotal step towards constructing a hybrid quantum supercomputing system capable of revolutionizing research and innovation across various industries.

???? Having a hybrid supercomputer with just 100 reliable quantum bits would offer scientific benefits while reaching 1,000 reliable bits would unlock commercial advantages across various industries.

???? This breakthrough opens the door to solving real-world problems with reliable quantum computers. This also means: Q-Day is getting closer and closer.

???? Quantum computers, when sufficiently developed, could dismantle the security protocols that guard our digital lives. Blockchain, the decentralized ledger underpinning web3 applications, dApss, cryptocurrencies and secure transactions, will also face vulnerabilities.

???? To be prepared for potential attacks, using a post-quantum cryptographic algorithm is of the highest importance for blockchain networks.
