ABSTRACT

Quantum sensing is rapidly advancing, offering powerful new tools for precision measurements that go beyond what’s possible with classical methods. In this talk, I’ll explore how continuous variable (CV) quantum systems are driving these breakthroughs. First, we’ll see how squeezed light can push sensitivity past the limits of traditional NOON states, allowing us to make ultra-precise measurements even when faced with noise. Next, I’ll highlight how quantum entanglement offers an exponential advantage in learning about complex systems, drastically reducing the number of measurements needed. Finally, we’ll look at cutting-edge mechanical oscillators designed with nearly perfect efficiency, opening the door for new quantum experiments at room temperature. These developments are paving the way for more accurate measurements and exciting applications in quantum technology.
