Scalable High-Dimensional Multipartite Entanglement with Trapped Ions
Harsh Vardhan Upadhyay, Sanket Kumar Tripathy, Ting Rei Tan +2
We propose a protocol for the preparation of generalized Greenberger-Horne-Zeilinger (GHZ) states of atoms each with or internal levels. We generalize the celebrated…
Optimal Multiparameter Metrology: The Quantum Compass Solution
Denis V. Vasilyev, Athreya Shankar, Raphael Kaubruegger +1
We study optimal quantum sensing of multiple physical parameters using repeated measurements. In this scenario, the Fisher information framework sets the fundamental limits on sens…
Optimal and Variational Multi-Parameter Quantum Metrology and Vector Field Sensing
Raphael Kaubruegger, Athreya Shankar, Denis V. Vasilyev +1
We study multi-parameter sensing of 2D and 3D vector fields within the Bayesian framework for quantum interferometry. We establish a method to determine the optimal quantum…
Steady-state spin synchronization through the collective motion of trapped ions
Athreya Shankar, John Cooper, Justin G. Bohnet +2
Ultranarrow-linewidth atoms coupled to a lossy optical cavity mode synchronize, i.e. develop correlations, and exhibit steady-state superradiance when continuously repumped. This t…
