Dual-species matter qubit entangled with light.
We propose and demonstrate an atomic qubit based on a cold 85Rb-87Rb isotopic mixture, entangled with a frequency-encoded optical qubit. The interface of an atomic qubit with a single spatial light mode, and the ability to independently address the two atomic qubit states, should provide the basic interferometrically robust element of a quantum network.
