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...
Generic Two-Qubit Photonic Gates Implemented by Number-Resolving Photodetection (2009)
Uskov, Dmitry B., Smith, A. Matthew, Kaplan, Lev
We combine numerical optimization techniques [Uskov et al., Phys. Rev. A 79, 042326 (2009)] with symmetries of the Weyl chamber to obtain optimal implementations of generic linear-optical KLM-type...
A Method to Modify RMT using Short-Time Behavior in Chaotic Systems (2009)
Smith, A. Matthew, Kaplan, Lev
We discuss a modification to Random Matrix Theory eigenstate statistics, that systematically takes into account the non-universal short-time behavior of chaotic systems. The method avoids...
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...
Inflationary dynamics for matrix eigenvalue problems (2007)
Heller, Eric J., Kaplan, Lev, Pollmann, Frank
Many fields of science and engineering require finding eigenvalues and eigenvectors of large matrices. The solutions can represent oscillatory modes of a bridge, a violin, the disposition of...
Acquisition and Mosaicing of Low-Contrast Background Radiometric Images for Scene Simulation (2007)
Lev Kaplan, Yossi Bushlin, Craig Gotsman
High resolution radiometric images of a large terrain were obtained by scanning the area with a downlooking imaging radiometer attached to a helicopter. A detailed description of the data acquisition...
Statistics of branched flow in a weak correlated random potential (2002)
Recent images of electron flow through a two-dimensional electron gas (2DEG) device show branching behavior that is reproduced in numerical simulations of motion in a correlated random potential...
Odd-even binding effect from random two-body interactions (2002)
Papenbrock, Thomas, Kaplan, Lev, Bertsch, George F.
Systematic odd-even binding energy differences in finite metallic particles are usually attributed to mean-field orbital energy effects or to a coherent pairing interaction. We show analytically and...
Spin Structure of Many-Body Systems with Two-Body Random Interactions (2000)
Kaplan, Lev, Papenbrock, Thomas, Johnson, Calvin W.
We investigate the spin structure of many-fermion systems with a spin-conserving two-body random interaction. We find a strong dominance of spin-0 ground states and considerable correlations between...
Wave Function Structure in Two-Body Random Matrix Ensembles (1999)
Kaplan, Lev, Papenbrock, Thomas
We study the structure of eigenstates in two-body interaction random matrix ensembles and find significant deviations from random matrix theory expectations. The deviations are most prominent in the...
Effects of Top Compositeness (1994)
Georgi, Howard, Kaplan, Lev, Morin, David, Schenk, Andreas
We investigate the effects of top quark compositeness on various physical parameters, and obtain lower limits on the compositeness scale from electroweak precision data. We consider corrections to...
Decays of $\ell=1$ Baryons --- Quark Model versus Large-$N_c$ (1994)
Carone, Christopher D., Georgi, Howard, Kaplan, Lev, Morin, David
We study nonleptonic decays of the orbitally excited, \su6 \rep{70}-plet baryons in order to test the hypothesis that the successes of the nonrelativistic quark model have a natural explanation in...
Inflationary dynamics for matrix eigenvalue problems
Heller, Eric J., Kaplan, Lev, Pollmann, Frank
Many fields of science and engineering require finding eigenvalues and eigenvectors of large matrices. The solutions can represent oscillatory modes of a bridge, a violin, the disposition of...
