Affine Maps of the Polarization Vector for Quantum Systems of Arbitrary Dimension
Mark S. Byrd, C. Allen Bishop, Yong-Cheng Ou
The operator-sum decomposition (OS) of a mapping from one density matrix to another has many applications in quantum information science. To this mapping there corresponds an affin…
New Approach To A Generalized Fractional Integral
Udita N. Katugampola
The paper presents a new formula for the fractional integration, which generalizes the Riemann-Liouville and Hadamard fractional integrals into a single form, which when a paramete…
Quantitative Excited State Spectroscopy of a Single InGaAs Quantum Dot Molecule through Multi-million Atom Electronic Structure Calculations
Muhammad Usman, Yui-Hong Matthias Tan, Hoon Ryu +4
Atomistic electronic structure calculations are performed to study the coherent inter-dot couplings of the electronic states in a single InGaAs quantum dot molecule. The experiment…
Tuning Jammed Frictionless Disk Packings from Isostatic to Hyperstatic
Carl F. Schreck, Corey S. O'Hern, Leonardo E. Silbert
We perform extensive computational studies of two-dimensional static bidisperse disk packings using two distinct packing-generation protocols. The first involves thermally quenchin…
Security of high speed quantum key distribution with finite detector dead time
Viacheslav Burenkov, Bing Qi, Ben Fortescue +1
The security of a high speed quantum key distribution system with finite detector dead time τ is analyzed. When the transmission rate becomes higher than the maximum count rate of…
All maps equivalent to a given map, completely positive or not
Yong-Cheng Ou, Mark S. Byrd
A dynamical map is a map which takes one density operator to another. Such a map can be written in an operator-sum representation (OSR) using a spectral decomposition. The method o…
