Quantum Metrology with Two-Mode Squeezed Vacuum: Parity Detection Beats the Heisenberg Limit
Petr M. Anisimov, Gretchen M. Raterman, Aravind Chiruvelli +4
We study the sensitivity and resolution of phase measurement in a Mach-Zehnder interferometer with two-mode squeezed vacuum (<n> photons on average). We show that super-resolution…

Parity Measurements in Quantum Optical Metrology
Aravind Chiruvelli, Hwang Lee
We investigate the utility of parity detection to achieve Heisenberg-limited phase estimation for optical interferometry. We consider the parity detection with several input states…
