Abstract

We report on the experimental demonstration of stimulated Raman adiabatic passage in a ${\text{Tm}}^{3+}:\text{YAG}$ crystal. ${\text{Tm}}^{3+}:\text{YAG}$ is a promising material for use in quantum information processing applications, but as yet there are few experimental investigations of coherent Raman processes in this material. We investigate the effect of inhomogeneous broadening and Rabi frequency on the transfer efficiency and the width of the two-photon spectrum. Simulations of the complete ${\text{Tm}}^{3+}:\text{YAG}$ system are presented along with the corresponding experimental results.

Experimental investigations of stimulated Raman adiabatic passage in a doped solid

Jens Klein, Fabian Beil, Thomas Halfmann

We report on experimental investigations of stimulated Raman adiabatic passage (STIRAP) in a ${\mathrm{Pr}}^{3+}:{\mathrm{Y}}_{2}\mathrm{Si}{\mathrm{O}}_{5}$ crystal. STIRAP drives complete, coherent population transfer between two hyperfine levels in the ${\mathrm{Pr}}^{3+}$ ions. We investigate the variation of the STIRAP transfer efficiency with the experimental parameters: e.g., detunings, Rabi frequencies, and pulse delays. In addition, we also observe an alternative and efficient, adiabatic transfer process---i.e., $b$ -STIRAP---which occurs for a reversed sequence of laser pulses. We compare the efficiencies and time-resolved transfer dynamics of STIRAP and $b$ -STIRAP. The experimental data are supported by numerical simulations, also including the effect of laser frequency jitter. Our experimental data and the numerical simulations provide a clear and convincing demonstration of adiabatic excitations in a solid medium.We report on experimental investigations of stimulated Raman adiabatic passage (STIRAP) in a ${\mathrm{Pr}}^{3+}:{\mathrm{Y}}_{2}\mathrm{Si}{\mathrm{O}}_{5}$ crystal.

Population transfer via stimulated Raman adiabatic passage in a solid

Hayato Goto, Kouichi Ichimura

We report experimental demonstration of population transfer via stimulated Raman adiabatic passage with a rare-earth-ion-doped crystal $({\mathrm{Pr}}^{3+}:{\mathrm{Y}}_{2}\mathrm{Si}{\mathrm{O}}_{5})$ . About 90% of population of a ground level is transferred to another ground level with two pulses whose width is shorter than the lifetime of the excited state. The dependence of transferred population on the delay time of the pulse sequence is also experimentally investigated. The delay-time dependence observed in our experiment is similar to that obtained by numerical simulation.We report experimental demonstration of population transfer via stimulated Raman adiabatic passage with a rare-earth-ion-doped crystal $({\mathrm{Pr}}^{3+}:{\mathrm{Y}}_{2}\mathrm{Si}{\mathrm{O}}_{5})$.

Robust Population Transfer by Stimulated Raman Adiabatic Passage in a Pr3+:Y2SiO5 Crystal

Jens Klein, Fabian Beil, Thomas Halfmann

We report on the experimental implementation of stimulated Raman adiabatic passage (STIRAP) in a Pr3+:Y2SiO5 crystal. Our data provide clear and striking proof for nearly complete population inversion between hyperfine levels in the Pr3+ ions. The transfer efficiency was monitored by absorption spectroscopy. Time-resolved absorption measurements serve to monitor the adiabatic population dynamics during the STIRAP process. Efficient transfer is observed for negative pulse delays (STIRAP), as well as for positive delays. We identify the latter by an alternative adiabatic passage process.We report on the experimental implementation of stimulated Raman adiabatic passage (STIRAP) in a Pr3+:Y2SiO5 crystal.

Picturing stimulated Raman adiabatic passage: a STIRAP tutorial

Bruce W. Shore

The procedure of stimulated-Raman adiabatic passage (STIRAP), one of many well-established techniques for quantum-state manipulation, finds widespread application in chemistry, physics, and information processing. Numerous reviews discuss these applications, the history of its development, and some of the underlying physics. This tutorial supplies material useful as background for the STIRAP reviews as well as related techniques for adiabatic manipulation of quantum structures, with emphasis on the theory and simulation rather than on experimental results. It particularly emphasizes the picturing of behavior in various abstract vector spaces, wherein torque equations offer intuition about adiabatic changes. Appendices provide brief explanations of related coherent-excitation topics and useful evaluations of relative strengths of coherent transitions—the Rabi frequencies—involving Zeeman sublevels.The procedure of stimulated-Raman adiabatic passage (STIRAP), one of many well-established techniques for quantum-state manipulation, finds widespread application in chemistry, physics, and information processing.

Experimental demonstration of composite stimulated Raman adiabatic passage

Alexander Bruns, Genko T. Genov, Marcel Hain +2 more

We experimentally demonstrate composite stimulated Raman adiabatic passage (CSTIRAP), which combines the concepts of composite pulse sequences and adiabatic passage. The technique is applied for population transfer in a rare-earth doped solid. We compare the performance of CSTIRAP with conventional single and repeated STIRAP, either in the resonant or the highly detuned regime. In the latter case, CSTIRAP improves the peak transfer efficiency and robustness, boosting the transfer efficiency substantially compared to repeated STIRAP. We also propose and demonstrate a universal version of CSTIRAP, which shows improved performance compared to the originally proposed composite version. Our findings pave the way towards new STIRAP applications, which require repeated excitation cycles, e.g., for momentum transfer in atom optics, or dynamical decoupling to invert arbitrary superposition states in quantum memories.We experimentally demonstrate composite stimulated Raman adiabatic passage (CSTIRAP), which combines the concepts of composite pulse sequences and adiabatic passage.

Adiabatic refocusing of nuclear spins in Tm 3+ :YAG

Romain Lauro, T. Chanelière, J.-L. Le Gouët

We show that the optical absorbance detection of nuclear spin echo gives direct access to the spin concentration, unlike most coherent signal detection techniques where the signal intensity/amplitude is difficult to connect experimentally with the spin concentration. This way we measure the spin-refocusing efficiency in a crystal of Tm ${}^{3+}$ :YAG. Given the large inhomogeneous broadening of the spin transition in this material, rephasing the spins with the usual hard pulse procedure would require excessively high radiofrequency power. Instead we resort to an adiabatic pulse sequence that perfectly returns the spins to their initial common orientation, at low power cost.We show that the optical absorbance detection of nuclear spin echo gives direct access to the spin concentration, unlike most coherent signal detection techniques where the signal intensity/amplitude is difficult to connect experimentally with the spin concentration.
