A, B, C of Three-Qubit Entanglement: Three Vectors to Control It All
Dmitry B. Uskov, Paul M. Alsing
In this paper we are focusing on entanglement control problem in a three-qubit system. We demonstrate that vector representation of entanglement, associated with SO(6) representati…
Optimal Fusion Transformations for Linear Optical Cluster State Generation
D. B. Uskov, P. Lougovski, P. M. Alsing +3
We analyze the generation of linear optical cluster states (LOCS) via addition of one and two qubits. Existing approaches employ the stochastic linear optical two-qubit CZ gate wit…
Success rates for linear optical generation of cluster states in coincidence basis
D. B. Uskov, P. M. Alsing, M. L. Fanto +2
We report on theoretical research in photonic cluster-state computing. Finding optimal schemes of generating non-classical photonic states is of critical importance for this field…
Imperfect Linear Optical Photonic Gates with Number-Resolving Photodetection
A. Matthew Smith, D. B. Uskov, L. H. Ying +1
We use the numerical optimization techniques of Uskov et al. [PRA 81, 012303 (2010)] to investigate the behavior of the success rates for KLM style [Nature 409, 46 (2001)] two- and…
Generic Two-Qubit Photonic Gates Implemented by Number-Resolving Photodetection
Dmitry B. Uskov, A. Matthew Smith, Lev Kaplan
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 absorption spectra and monomer interaction in polymers. Investigation of exciton coupling in DNA hairpins
A. L. Burin, J. A. Dickman, D. B. Uskov +2
We investigate the effect of exciton coupling on the optical absorption spectrum of polymer molecules under conditions of strong inhomogeneous broadening. We demonstrate that the d…
