Google, major breakthrough in quantum computing

Google has verified a technology called "magic state cultivation" on its Willow processor, which has drastically reduced the quantum error rate.

It is understood that in quantum computing, photons (or light particles) are used as qubits.

However, qubits are prone to frequent errors, so quantum computers still have limitations at present.

"Magic states" are the key element to realize universal quantum computing.

Moreover, generating magic states with a sufficiently low error rate has long been a major challenge in building practical large-scale systems.
