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 focus on sensing and precision metrology enhanced by entanglement, a unique and radically new resource for information processing. I will describe our recent experimental advances in entanglement-based quantum machine learning for data classification and entangled sensor networks for precise radiofrequency and optomechanical sensing. A pathway toward large-scale quantum sensor networks and prospects for future applications underpinned by quantum-enhanced sensing will also be discussed.
