Over the last century, quantum mechanics has driven transformative technological progress and reshaped the world through inventions such as lasers and semiconductors. In particular, quantum effects underpin intriguing phenomena defying classical intuition and unprecedented information processing capabilities, with an example being quantum computers. However, real-world quantum systems are inevitably coupled to their surrounding environment, which renders them essentially “open” and introduces decoherence and noise that usually obscure and destroy genuine quantum properties. Such impacts are especially detrimental for maintaining coherent control over large quantum systems with many particles, presenting a major challenge for advancing the frontiers of quantum technologies. This project aims to address this challenge by developing new protocols for preserving interesting quantum properties and unraveling associated quantum phenomena in open systems comprising many particles. The protocols will feature setups relevant to a number of existing and emerging quantum platforms. The proposed research will help enhance the capabilities for controlling quantum systems, which has applications ranging from quantum information processing to quantum metrology. In addition, the work conducted will enable advances in the physics of quantum systems subject to interactions with classical environments. In parallel with these research activities, this project incorporates a multi-layered educat
