Motivation

Laser cooling techniques have transformed atomic, molecular, and optical (AMO) physics by enabling precise quantum control at microkelvin and sub-microkelvin temperatures. Traditional approaches, such as Doppler and sub-Doppler cooling, have long been instrumental in preparing quantum gases. More recent cooling innovations extend these capabilities o species and regimes that were previously inaccessible, enabling frontier applications in quantum simulation [Greiner, et al.], timekeeping [Chen&Ludlow (2024), Chen&Katori(2025)], and quantum information science through techniques like erasure cooling [Endres, et al.].

Our research focuses on narrow-line laser cooling utilizing ultranarrow optical clock transitions, aiming to integrate these techniques into multiplexed operations and extended coherent control over multiple trapping sites. Such integration is essential for developing large-scale processor architectures and ensuring the continuous operation of coherent qubit systems in next-generation quantum technologies.
