Abstract: The 20th century has witnessed the rise of quantum mechanics and its fueled scientific and technological revolution. The humankind is now on the verge of a second quantum revolution sparked by quantum information science and engineering (QISE). Entanglement as a
quintessential quantum resource lies at the heart of QISE, giving rise to a plethora of quantum-enabled or enhanced capabilities that shift the landscape of communication, sensing, and computing. This talk will present a full-stack QISE approach building on foundational quantum
materials, to functional quantum devices, and finally toward system-level entanglement-based applications. I will describe our recent experimental advances in entanglement-based QISE, including quantum machine learning for data classification, entangled sensor networks for
precise radiofrequency and optomechanical sensing, and entanglement-assisted communication surpassing the ultimate classical capacity. Next, I will introduce two major endeavors to foster the transition from basic quantum research to near-term, widely impactful real-world quantum
technologies: the development of scalable quantum photonics materials and devices and the construction of the Interdisciplinary Quantum Information Research and Engineering (INQUIRE) testbed, a distributed infrastructure to advance convergent QISE research and
