Summary

Story summary

Researchers from the University of Chicago and collaborators developed molecular qubits that operate at telecom frequencies, enabling direct fiber-network integration.
The qubits could enable ultra-secure communication and link quantum computers over long distances.
They are compatible with silicon photonics and use erbium, a rare-earth element, to provide clean light absorption and strong magnetic-field interaction.
