Exploring the dynamical interplay between mass-energy equivalence, interactions and entanglement in an optical lattice clock
Anjun Chu, Victor J. Martínez-Lahuerta, Maya Miklos +5
We propose protocols that probe manifestations of the mass-energy equivalence in an optical lattice clock (OLC) interrogated with spin coherent and entangled quantum states. To tun…

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…
