Quantum advantage in continuous variable optical quantum sensing and learning

Quantum technologies are enhancing our ability to sense and learn about the physical world, unlocking capabilities beyond classical limits. In this talk, I will present recent advancements in continuous variable (CV) quantum systems in establishing a quantum advantage in both sensing and learning. I will demonstrate how squeezed light enables ultra-precise measurements, surpassing the sensitivity of traditional NOON states even in noisy environments, and how variational algorithms can be employed on this platform to adaptively optimize the probe state and measurement strategies for high-precision optical phase sensing. Additionally, I will explore how quantum entanglement provides an exponential advantage in learning complex bosonic systems, drastically reducing the measurement overhead. These advancements illustrate the potential of CV quantum systems, setting the stage for novel applications in precision measurement and quantum technologies.
