Abstract

The precision of atom interferometry is affected by system errors due to the laser parameters and atomic velocity. We propose the method of the Stimulated Raman Adiabatic Passage(STIRAP) to enhance the accuracy of the atom interferometry and its tolerance for the environment. We calculate the fidelity of the target atomic state for the cases of the STIRAP technique, rectangular pulse and Gaussian pulse. It is shown that the fidelity of the atomic state obtained with the STIRAP technique is higher than that with rectangular pulse and Gaussian pulse. In addition, higher interference fringe contrast of the atom interferometry can be obtained with the pulse sequence consisting of STIRAP than the rectangular pulse sequence and Gaussian pulse sequence. This scheme may have promising applications in precise measurements with atom interferometry.

IMPROVED ATOM INTERFEROMETER PERFORMANCE USING COUNTERINTUITIVE STIMULATED RAMAN ADIABATIC PASSAGE

Tatasciore, Branden

Atom interferometers depend on light/matter interactions and are extremely sensitive sensors capable of being employed as accelerometers, rotation sensors, and gravity and magnetic gradiometers. Typical interferometers use a well-known velocity (generally from atoms launched out of an atomic trap) to interferometrically measure quantities of interest (e.g., acceleration and rotation). This thesis evaluates the effects of atom velocity in an atom interferometer sensor that exists at NPS, which uses a continuous beam of cold rubidium atoms with a narrow but not monochromatic range of velocities passing through continuous laser fields. The atom’s velocity dictates the interaction time between the atom and laser. However, this combination results in pulse errors due to velocity averaging. One method to counteract these pulse errors uses the so-called counterintuitive laser arrangement—a method known as stimulated Raman adiabatic passage (STIRAP). STIRAP will be shown to be a more robust approach. Starting with the atoms in one of the ground states, all or a portion of the atoms can be transferred to the other ground state in a well-controlled manner. Changes in acceleration and rotation can be sensed with very high precision by a detection laser resulting in applicability as a highly sensitive accelerometer or gyroscope. This project explores experimentally and theoretically the utility of counterintuitive pulse sequences for atom interferometry applications.

Optimized pulse for stimulated Raman adiabatic passage on noisy experimental platform*

Zhiling Wang, Leiyinan Liu, Jian Cui

Stimulated Raman adiabatic passage (STIRAP) is an important technique to manipulate quantum states in quantum simulation and quantum computation. The transformation fidelity is limited in reality due to experimental imperfections. After systematically calculating the influence of dissipation caused by thermal fluctuations and instantaneous decay of the intermediate state, we find optimized control pulses of Rydberg atom in optical tweezer to increase the STIRAP fidelity via optimal control method. All constraints of currently available control lasers have been taken into account. The transition error can be further depressed when control lasers with shorter rise time and accordingly proper total evolution time are applied. Finally, the robustness of the control pulses with respect to random deviations between the theoretical pulse shape and the implemented ones is also enhanced by additional rounds of optimizations based on ensemble averaged fidelity.

Geometric atom interferometry with shortcuts to adiabaticity

Yan-Xiong Du, Xian-Xian Yue, Zhen-Tao Liang +3 more

Realization of the highly efficient $\ensuremath{\pi}$ and $\ensuremath{\pi}/2$ pulses is crucial in an atom interferometry. Here we propose a scheme to realize these operations based on an intrinsically fault-tolerant geometric phase and stimulated Raman shortcuts to the adiabatic passage. The scheme is fast due to the shortcuts to adiabaticity and is robust based on the geometric phase. In the presence of various noises, we show that the fringe contrast of the proposed interferometer is higher than that of the resonant Raman pulse and the stimulated Raman adiabatic passage. Furthermore, the scheme is demonstrated to be especially suitable for applications that require a large space-time area enclosed by interfering wave packets.

Composite stimulated Raman adiabatic passage

Boyan T. Torosov, Nikolay V. Vitanov

We introduce a high-fidelity technique for coherent control of three-state quantum systems, which combines two popular control tools---stimulated Raman adiabatic passage (STIRAP) and composite pulses. By using composite sequences of pairs of partly delayed pulses with appropriate phases, the nonadiabatic transitions, which prevent STIRAP from reaching unit fidelity, can be canceled to an arbitrary order by destructive interference, and therefore, the technique can be made arbitrarily accurate. The composite phases are given by simple analytic formulas, and they are universal for they do not depend on the specific pulse shapes, the pulse delay, and the pulse areas.

Experimental realization of stimulated Raman shortcut-to-adiabatic passage with cold atoms

Yan-Xiong Du, Zhen-Tao Liang, Yichao Li +6 more

Accurate control of a quantum system is a fundamental requirement in many areas of modern science ranging from quantum information processing to high-precision measurements. A significantly important goal in quantum control is preparing a desired state as fast as possible, with sufficiently high fidelity allowed by available resources and experimental constraints. Stimulated Raman adiabatic passage (STIRAP) is a robust way to realize high-fidelity state transfer but it requires a sufficiently long operation time to satisfy the adiabatic criteria. Here we theoretically propose and then experimentally demonstrate a shortcut-to-adiabatic protocol to speed-up the STIRAP. By modifying the shapes of the Raman pulses, we experimentally realize a fast and high-fidelity stimulated Raman shortcut-to-adiabatic passage that is robust against control parameter variations. The all-optical, robust and fast protocol demonstrated here provides an efficient and practical way to control quantum systems.
