Time-Reversal and Reversible Dynamics in Cavity QED for Quantum Metrology
Simone Colombo, Edwin Pedrozo-Peñafiel
Quantum-enhanced metrology relies on entanglement to achieve sensitivities beyond the standard quantum limit. While remarkable progress has been made in generating highly entangled…

Time-reversal Interferometry Using Cat States with Scalable Entangling Resources
Sebastián C. Carrasco, Michael H. Goerz, Zeyang Li +4
We propose a novel method for generating Schrödinger-cat states -- defined as equal superpositions of arbitrary coherent states -- using a concise sequence of rapid twist-and-turn…

Quantum-amplified global-phase spectroscopy on an optical clock transition
Leon Zaporski, Qi Liu, Gustavo Velez +5
Optical lattice clocks (OLCs) are at the forefront of precision metrology, operating near a standard quantum limit (SQL) set by quantum noise. Harnessing quantum entanglement offer…
