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 …

Scalable Passive Optical Masks That Enable One- and Two-Species Atom-Trap Arrays

2024

We report a passive approach for trapping arrays of neutral atoms of one or two species, using a single laser. Compared to active setups, e.g., spatial light modulators, our approach is simple, compact, and robust.
