Abstract

Quantum technologies, spanning from sensing and metrology to simulations and computing, rely upon precise and low noise laser systems. Currently, we are witnessing a paradigm shift, where laboratory-based experiments are engineered such to develop reliable operating devices. The goal of providing continuous operation is key to enable their deployment for, e.g., PNT applications or cloud-based quantum computing services. Ultra-low noise laser systems are becoming integral part of these quantum devices due to their pivotal role in the effective functioning of the physics package. In fact, the performance are fundamentally linked to the noise properties of the driving laser fields, imposing the need of a careful choice of the appropriate sources, their spectral properties, and their stabilization. Here we present some of our recent ultra-stable laser system engineered for enabling several applications, we will describe ultra-stable comb and laser systems for quantum computing using neutral Yb, Sr, Rb, or Cs atoms, electric field sensing with Rydberg Rb atoms, and portable compact comb systems to enable uninterrupted operation of optical clocks in the field. A detailed noise analysis of the systems will be presented.
