"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

If you’ve ever sent a text message, played a CD, or stored a file in the cloud, you’ve benefited from error correction. This revolutionary idea dates back to the ...

There’s widespread agreement that most useful quantum computing will have to wait for the development of error-corrected qubits. Error correction involves ...

Today’s quantum computing hardware is severely limited in what it can do by errors that are difficult to avoid. There can be problems with everything from setting the initial state of a qubit to ...

Schematics of EFBQC. In a fusion network, the photons participating in fusions are encoded in a QEC code, and an encoded-fusion protocol is performed actively in a concatenative manner between encoded ...

Quantum computers are a little like librarians: both abhor noise. Compared with their classical counterparts, quantum computers are finicky and need a serene environment to perform their calculations ...

For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...

All complex biological systems—like the DNA, RNA and proteins constantly being copied and built within our cells—are prone to errors. That means as life evolved to be more elaborate, it also had to ...

Astronaut John Glenn was wary about trusting a computer. It was 1962, early in the computer age, and a room-sized machine had calculated the flight path for his upcoming orbit of Earth — the first for ...
