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…
Numerical Simulations of 3D Ion Crystal Dynamics in a Penning Trap using the Fast Multipole Method
John Zaris, Wes Johnson, Athreya Shankar +2
We simulate the dynamics, including laser cooling, of 3D ion crystals confined in a Penning trap using a newly developed molecular dynamics-like code. The numerical integration of…
Quantum Synchronization and Dissipative Quantum Sensing
Gaurav M. Vaidya, Simon B. Jäger, Athreya Shankar
We study the phenomenon of quantum synchronization from the viewpoint of quantum metrology. By interpreting quantum self-sustained oscillators as dissipative quantum sensors, we de…
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…
Bilayer crystals of trapped ions for quantum information processing
Samarth Hawaldar, Prakriti Shahi, Allison L. Carter +3
Trapped ion systems are a leading platform for quantum information processing, but they are currently limited to 1D and 2D arrays, which imposes restrictions on both their scalabil…
