Coherence and Rydberg Blockade of Atomic Ensemble Qubits

2015 · Physical Review Letters

We demonstrate |W⟩ state encoding of multiatom ensemble qubits. Using optically trapped Rb atoms, the T_{2} coherence time is 2.6(3) ms for N[over ¯]=7.6 atoms and scales approximately inversely with the number of atoms. Strong …
