quantum computing industry

Cloudflare announced on Tuesday that it plans to issue quantum-proof TLS certificates, positioning itself among the first certificate authorities to use cryptography widely believed to withstand attacks from quantum computers. The move anticipates a future in which quantum machines could break today's encryption, and it puts the web infrastructure company ahead of much of the industry in securing internet traffic against that threat.

Researchers have proposed a new definition for scalable logical qubits, the error-corrected building blocks needed for practical quantum computers. A clearer standard for what counts as a scalable logical qubit could help labs and companies measure progress toward fault-tolerant machines and compare results across different quantum computing platforms.
