Density Matrix From Photon Number Tomography
We provide a simple analytic relation which connects the density operator of the radiation field with the number probabilities. The problem of experimentally ”sampling” a general matrix elements is studied, and the deleterious effects of nonunit quantum efficiency in the detection process are analyzed showing how they can be reduced by using the squeezing technique. The obtained result is parti...
متن کاملDensity Matrix Estimation in Quantum Homodyne Tomography
Modern scientific studies often involve complex quantum systems, and scientists need to learn the systems from experimental data. As density matrices are usually employed to characterize the quantum states of the systems, this paper investigates estimation of density matrices. We propose statistical methodologies to construct density matrix estimators and establish an asymptotic theory for the ...
متن کاملDiffraction tomography for biochemical imaging with diffuse-photon density waves.
The spatial structure of optically heterogeneous turbid media is probed with diffusive light. Projection images are obtained experimentally by deconvolution of the scattered diffuse-photon density waves on a planar boundary by use of a fast Fourier transform. The method is very fast, permitting object localization and characterization in ~1000 volume-element samples on subsecond computational t...
متن کاملNear-field diffraction tomography with diffuse photon density waves.
An angular spectrum algorithm is presented for fast, near-field diffraction tomographic imaging with diffuse photon density waves in highly scattering media. A general relation in K space is derived that connects the spatial variations of the optical properties of heterogeneities to the spatial spectra of the measured scattered diffuse photon density waves. The theory is verified experimentally...
متن کاملFrom density-matrix renormalization group to matrix product states
In this paper we give an introduction to the numerical density matrix renormalization group (DMRG) algorithm, from the perspective of the more general matrix product state (MPS) formulation. We cover in detail the differences between the original DMRG formulation and the MPS approach, demonstrating the additional flexibility that arises from constructing both the wavefunction and the Hamiltonia...
