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...
Optimization of quantum interferometric metrological sensors in the presence of photon loss (2009)
Lee, Tae-Woo, Huver, Sean D., Lee, Hwang, Kaplan, Lev, McCracken, Steven B., Min, Changjun, ...
We optimize two-mode, entangled, number states of light in the presence of loss in order to maximize the extraction of the available phase information in an interferometer. Our approach optimizes...
Maximal Success Probabilities of Linear-Optical Quantum Gates (2008)
Uskov, Dmitry B., Kaplan, Lev, Smith, A. Matthew, Huver, Sean D., Dowling, Jonathan P.
Numerical optimization is used to design linear-optical devices that implement a desired quantum gate with perfect fidelity, while maximizing the success rate. For the 2-qubit CS (or CNOT) gate, we...
Entangled Fock states for Robust Quantum Optical Metrology, Imaging, and Sensing (2008)
Huver, Sean D., Wildfeuer, Christoph F., Dowling, Jonathan P.
We propose a class of path-entangled photon Fock states for robust quantum optical metrology, imaging, and sensing in the presence of loss. We model propagation loss with beam-splitters and derive a...
Optimizing Optical Quantum Logic Gates using Genetic Algorithms (2007)
Wu, Zhanghan, Huver, Sean D., Uskov, Dmitry, Lee, Hwang, Dowling, Jonathan P.
We introduce the method of using an annealing genetic algorithm to the numerically complex problem of looking for quantum logic gates which simultaneously have highest fidelity and highest success...
