Optimizing qubit Hamiltonian parameter estimation algorithms using PSO
Alexandr Sergeevich, Stephen D. Bartlett
We develop qubit Hamiltonian single parameter estimation techniques using a Bayesian approach. The algorithms considered are restricted to projective measurements in a fixed basis,…
Characterization of a qubit Hamiltonian using adaptive measurements in a fixed basis
Alexandr Sergeevich, Anushya Chandran, Joshua Combes +2
We investigate schemes for Hamiltonian parameter estimation of a two-level system using repeated measurements in a fixed basis. The simplest (Fourier based) schemes yield an estima…
Scaling Separability Criterion: Application To Gaussian States
Alexandr Sergeevich, Vladimir I. Man'ko
We introduce examples of three- and four-mode entangled Gaussian mixed states that are not detected by the scaling and Peres-Horodecki separability criteria. The presented modifica…
Frank-Condon principle and adjustment of optical waveguides with nonhomogeneous refractive indices
Vladimir I. Man'ko, Leonid D. Mikheev, Alexandr Sergeevich
The adjustment of two different selfocs is considered using both exact formulas for the mode-connection coefficients expressed in terms of Hermite polynomials of several variables…
