Coherent excitation and stimulated emission from optical transitions has been proposed as a mechanism to generate strong coherent forces in atomic systems and as the basis for fast quantum gates in trapped ions. We have demonstrated driving coherent oscillations between the 2S1/2 and 2P1/2 states in trapped 171Yb+ with 2.5 ps pulses straddling the resonance at 369.5nm. At higher powers nearly full extinction was observed, demonstrating coherence, however residual detuning issues have precluded full coherent population transfer.

Abstract
Coherent excitation and stimulated emission from optical transitions has been proposed as a mechanism to generate strong coherent forces in atomic systems and as the basis for fast quantum gates in trapped ions. We have demonstrated driving coherent oscillations between the 2S1/2 and 2P1/2 states in trapped 171Yb+ with 2.5 ps pulses straddling the resonance at 369.5nm. At higher powers nearly full extinction was observed, demonstrating coherence, however residual detuning issues have precluded full coherent population transfer.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
