A robust, fiber-coupled scanning probe magnetometer using electron spins at the tip of a diamond nanobeam

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Yufan Li, Gesa Welker, Richard Norte, Toeno van der Sar, | Summary: Fiber-coupled sensors are well suited for sensing and microscopy in hard-to-reach environments such as biological or cryogenic systems. We demonstrate fiber-based magnetic imaging based on nitrogen-vacancy (NV) sensor spins at the tip of […]

Universal scaling solution for a rigidity transition: renormalization group flows near the upper critical dimension

Kavli Affiliate: Itai Cohen | First 5 Authors: Stephen J. Thornton, Danilo B. Liarte, Itai Cohen, James P. Sethna, | Summary: Rigidity transitions induced by the formation of system-spanning disordered rigid clusters, like the jamming transition, can be well-described in most physically relevant dimensions by mean-field theories. However, we lack a theoretical description of these […]

All-optical Loss-tolerant Distributed Quantum Sensing

Kavli Affiliate: Alireza Marandi | First 5 Authors: Rajveer Nehra, Changhun Oh, Liang Jiang, Alireza Marandi, | Summary: 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 analyze an all-optical resource-efficient scheme for the next-generation DQS systems. Our method […]
