Progress in quantum metrology and applications for optical atomic clocks
Raphael Kaubruegger, Adam M. Kaufman
Quantum entanglement offers powerful opportunities for enhancing measurement sensitivity beyond classical limits, with optical atomic clocks serving as a leading platform for such…
Time complexity in preparing metrologically useful quantum states
Carla M. Quispe Flores, Raphael Kaubruegger, Minh C. Tran +3
We investigate the fundamental time complexity, as constrained by Lieb-Robinson bounds, for preparing entangled states useful in quantum metrology. We relate the minimum time to th…
Generating Entangled Steady States in Multistable Open Quantum Systems via Initial State Control
Diego Fallas Padilla, Raphael Kaubruegger, Adrianna Gillman +2
Entanglement underpins the power of quantum technologies, yet it is fragile and typically destroyed by dissipation. Paradoxically, the same dissipation, when carefully engineered,…
Lieb-Mattis states for robust entangled differential phase sensing
Raphael Kaubruegger, Diego Fallas Padilla, Athreya Shankar +9
We explore a two-node, entanglement-enhanced sensor network for differential phase sensing that exploits decoherence-free subspaces to suppress common-mode noise, a primary limitat…
