Trapping molecules to perform quantum operations. By carefully controlling how the molecules rotated with respect to one another, the team managed to entangle two molecules, creating a quantum state known as a two-qubit Bell state with 94 percent accuracy. The iSWAP gate used in this experiment swapped the states of two qubits and applied what is called a phase shift, an essential step in generating entanglement where the states of two qubits become correlated regardless of the distance in between.

So progress. For the uninitiated like me it does sound like baby steps though.
