All-optical Loss-tolerant Distributed Quantum Sensing
Rajveer Nehra, Changhun Oh, Liang Jiang +1
Distributed quantum sensing (DQS) leverages quantum resources to estimate an unknown global property of a networked quantum sensor beyond the classical limit. We propose and analyz…
Mesoscopic ultrafast nonlinear optics -- The emergence of multimode quantum non-Gaussian physics
Ryotatsu Yanagimoto, Edwin Ng, Marc Jankowski +8
Over the last few decades, nonlinear optics has become significantly more nonlinear, traversing nearly a billionfold improvement in energy efficiency, with ultrafast nonlinear nano…
