Collective Quantum Logic Spectroscopy
Raphael Kaubruegger, Matthew Patkowski, Yicheng Zhang +3
Scaling trapped-ion quantum sensors from single ions to large ensembles is a key challenge for next-generation precision measurements. At the same time, many ion species of interes…
Motional Kerr-Cat States of an Atom in an Optical Tweezer
Steven K. Pampel, Gur Lubin, Dawson P. Hewatt +6
Schrödinger cat states - quantum superpositions of classically or macroscopically distinct states - constitute a powerful resource for quantum computing, enhanced metrology, and pr…
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,…
