Neutral-atom arrays with single-particle detection and control are a powerful tool for quantum science. In this defense, I present results from two projects, both performed with the same tweezer-programmable neutral-strontium-array apparatus. First, we engineer Rydberg interactions to create entangled spin-squeezed states, whose measurement noise can outperform classical limits. In a synchronous optical-frequency comparison between two spin-squeezed ensembles of atoms, we realize a measurement with a stability better than the standard quantum limit.

Description: This training was developed by the Center for the Improvement of Mentored Experiences in Research (CIMER) at University of Wisconsin Madison and provides evidence-based, interactive mentor training curricula that engages mentors in collective problem solving and connects them with resources to optimize their mentoring practices. Mentors engage in activities, assignments, case studies, and facilitated discussions to solve mentoring dilemmas and share successful mentorship strategies.

Learning Objectives:

Ultracold polar molecules are an exciting platform for quantum science and technology. The combination of rich internal structure of vibration and rotation, controllable long-range dipolar interactions and strong coupling to applied electric and microwave fields has inspired many applications. These include quantum simulation of strongly interacting many-body systems, the study of quantum magnetism, quantum metrology and molecular clocks, quantum computation, precision tests of fundamental physics and the exploration of ultracold chemistry.

Polyaromatic hydrocarbons (PAHs) are ubiquitous in astrochemistry and are si

Abstract: Efforts on quantum simulation and computation have lead to the realization of well-controlled quantum many-body systems. Due to practical constraints, they are inevitably open, i.e., coupled to the environment, which generally leads to decoherence but can also be used to stabilize interesting states. In the thermodynamic limit, the nonequilibrium steady states can undergo phase transitions due to the competition of unitary and driven-dissipative processes. After recalling general properties, we will discuss first simple examples.

Single atoms and molecules are the emerging frontier in engineering applications as they represent the ultimate limit of modern electronic and photonic devices. While controlling at these extremely small scales have become a reality, the understanding of energy transport, conversion, and dissipation properties of these systems is falling behind due to the lack of experimental tools.
