Sharing a secret... the quantum way

Researchers at the University of the Witwatersrand in Johannesburg, South Africa, have demonstrated a record setting quantum protocol for sharing a secret amongst many parties. The team created an 11-dimensional quantum state ...

Connecting the quantum internet

Researchers at the Kastler Brossel Laboratory in Paris have succeeded in implementing a novel "hybrid" entanglement swapping protocol, bringing within reach the connection of disparate platforms in a future, heterogeneously ...

Laser loop couples quantum systems over a distance

For the first time, researchers have succeeded in creating strong coupling between quantum systems over a great distance. They accomplished this with a novel method in which a laser loop connects the systems, enabling nearly ...

Scientists tap into AI to put a new spin on neutron experiments

Scientists seek to use quantum materials—those that have correlated order at the subatomic level—for electronic devices, quantum computers, and superconductors. Quantum materials owe many of their properties to the physics ...

Tiny optical cavity could make quantum networks possible

Engineers at Caltech have shown that atoms in optical cavities—tiny boxes for light—could be foundational to the creation of a quantum internet. Their work was published on March 30 by the journal Nature.

Researchers demonstrate the missing link for a quantum internet

A quantum internet could be used to send unhackable messages, improve the accuracy of GPS, and enable cloud-based quantum computing. For more than twenty years, dreams of creating such a quantum network have remained out ...
