China team boosts atom entanglement distance record fourfold

Key facts

• A Chinese research team has achieved a new record for atom entanglement distance.
• The team successfully entangled atoms over a distance of 100 kilometers.
• This new record is four times greater than previous achievements.
• The breakthrough is crucial for developing secure quantum communication networks.

A team of researchers in China has significantly advanced the field of quantum communication by establishing a new record for the distance over which atoms can be entangled. The team successfully entangled atoms across a distance of 100 kilometers, which is four times greater than previous benchmarks.

This achievement is a critical step towards building secure and robust quantum communication networks. Entanglement, a phenomenon where particles become linked and share the same fate regardless of distance, is a fundamental principle for quantum cryptography and quantum computing. Extending the distance over which this link can be maintained is essential for practical applications.
