| Abstract: A method for preparing an entangled quantum state of an atomic ensemble
is provided. The method includes loading each atom of the atomic ensemble
into a respective optical trap; placing each atom of the atomic ensemble
into a same first atomic quantum state by impingement of pump radiation;
approaching the atoms of the atomic ensemble to within a dipole-dipole
interaction length of each other; Rydberg-dressing the atomic ensemble;
during the Rydberg-dressing operation, exciting the atomic ensemble with
a Raman pulse tuned to stimulate a ground-state hyperfine transition from
the first atomic quantum state to a second atomic quantum state; and
separating the atoms of the atomic ensemble by more than a dipole-dipole
interaction length. |
