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…
Hybrid qubit-oscillator module from motional states of two interacting atoms
Jaeyong Hwang, Tianrui Xu, Sean R. Muleady +5
We propose a qubit-oscillator platform based on the motional states of two interacting atoms in an optical tweezer. By stroboscopically modulating an engineered trap with tunable a…
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…
The Hong-Ou-Mandel effect with atoms
A. M. Kaufman, M. C. Tichy, F. Mintert +2
Controlling light at the level of individual photons has led to advances in fields ranging from quantum information and precision sensing to fundamental tests of quantum mechanics.…
Spectrum estimation of density operators with alkaline-earth atoms
Michael E. Beverland, Jeongwan Haah, Gorjan Alagic +3
We show that Ramsey spectroscopy of fermionic alkaline-earth atoms in a square-well trap provides an efficient and accurate estimate for the eigenspectrum of a density matrix whose…
