Quantum Metrology with Two-Mode Squeezed Vacuum: Parity Detection Beats the Heisenberg Limit (2009)
Anisimov, Petr M., Raterman, Gretchen M., Chiruvelli, Aravind, Plick, William N., Huver, Sean D., Lee, Hwang, ...
We study the sensitivity and resolution of phase measurement in a Mach-Zehnder interferometer with two-mode squeezed vacuum ( photons on average). We show that super-resolution and sub-Heisenberg...
Optimizing the Multi-Photon Absorption Properties of N00N States (2009)
Plick, William N., Wildfeuer, Christoph F., Anisimov, Petr M., Dowling, Jonathan P.
In this paper we examine the N-photon absorption properties of "N00N" states, a subclass of path entangled number states. We consider two cases. The first involves the N-photon absorption properties...
