Entanglement Levels Up

Extending a key resource of quantum technology, entanglement—either by having more than two quantum objects or using “qudits” instead of “qubits”—offers prospects for improvements in quantum communications, computation and other technologies.

The First Time the Laser Was Classified

An argument between Bell Labs and ARPA in 1959 led to classification of a million-dollar ARPA project to make the first laser—and delayed the laser efforts of both parties.
