States of an Ensemble of Two-Level Atoms with Reduced Quantum Uncertainty
We generate entangled states of an ensemble of 5×10[superscript 4] [superscript 87]Rb atoms by optical quantum nondemolition measurement. The resonator-enhanced measurement leaves the atomic ensemble, prepared in a superposition of hyperfine clock levels, in a squeezed spin state. By comparing the r...
