论文摘要
使用超鼻涕光学时钟过渡和复合脉冲的新一代原子传感器正在将量子工程控制推向非常高的应用和基本物理学的精度。在这里，我们提出了一种新版本的Ramsey-Bordé干涉法引入了任意复合激光脉冲，并具有量身定制的脉冲持续时间，Rabi场，失调和相位步骤。我们通过微调光激发参数的微调控制来保护超鼻子光学时钟过渡，以抵抗与激光探针场波动的残留轻偏变耦合，从而探索$ 10^{-18} $分数精度的水平。我们首次提出了针对强大的Hyper Ramsey-Bordé和Mach-Zehnder干涉仪的新发展，我们在其中保护波袋干扰与与残留多普勒效应相关的频率或相位测量的失真，并耦合到脉冲面积误差。具有复合脉冲和超冷来源的量子物质波传感器将提供惯性效应，以更好的精度诱导相移，以产生过度舒适的光学时钟并改善基本物理学的测试，以实现一类新的原子干涉仪跟踪具有很高敏感性的原子干涉仪跟踪时空雷值。
A new generation of atomic sensors using ultra-narrow optical clock transitions and composite pulses are pushing quantum engineering control to a very high level of precision for applied and fundamental physics. Here, we propose a new version of Ramsey-Bordé interferometry introducing arbitrary composite laser pulses with tailored pulse duration, Rabi field, detuning and phase-steps. We explore quantum metrology below the $10^{-18}$ level of fractional accuracy by a fine tuning control of light excitation parameters protecting ultra-narrow optical clock transitions against residual light-shift coupled to laser-probe field fluctuation. We present, for the first time, new developments for robust hyper Ramsey-Bordé and Mach-Zehnder interferometers, where we protect wavepacket interferences against distortion on frequency or phase measurement related to residual Doppler effects and light-shifts coupled to a pulse area error. Quantum matter-wave sensors with composite pulses and ultra-cold sources will offer detection of inertial effects inducing phase-shifts with better accuracy, to generate hyper-robust optical clocks and improving tests of fundamental physics, to realize a new class of atomic interferometers tracking space-time gravitational waves with a very high sensitivity.
