W-State Characterization and Progress Toward Non-Destructive State-Selective Measurements with an EMCCD Camera in Rb

POSTER

Abstract

We present a method for differentiating k-partite W-State entanglement from other singly-excited states, under the assumption that there are less than two excitations, valid for Rydberg blockade experiments. We use this method to demonstrate ~9 atom W-State entanglement generation via Rydberg blockade with two separate state rotations: a Jx Microwave rotation experiment and a Jz Ramsey fringe experiment. We also report progress towards a non-destructive state-selective readout with an EMCCD camera, which could increase experimental data rates significantly.
