Time Dependent Variational Principle and Coherent State Orbits for a Trapped Ion
Time Dependent Variational Principle Coherent State Orbits Trapped Ion
2011/9/29
Abstract: Spectral properties of the Hamiltonian function which characterizes a trapped ion are investigated. In order to study semiclassical dynamics of trapped ions, coherent state orbits are introd...
Coherent state transfer via highly mixed quantum spin chains
quantum spin chains coherent state transfer Quantum Physics
2010/11/8
Spin chains have been proposed as quantum wires in many quantum information processing architectures. Coherent transmission of quantum information over short distances is enabled by their internal dyn...
Entanglement dynamics via coherent-state propagators
Entanglement dynamics coherent-state propagators
2010/10/19
The dynamical generation of entanglement in closed bipartite systems is investigated in the semi-classical regime. We consider a model of two particles, initially prepared in a product of coherent sta...
Quantum Interference between a Single-Photon Fock State and a Coherent State
Quantum Interference Single-Photon Fock State Coherent State

ports of a beam splitter when a single-photon Fock state and a coherent state are incident on
the input ports. The output states turn out to be a statistical mixture between a displaced Fock state an...
Scheme for generating coherent state superpositions with realistic cross-Kerr nonlinearity

2010/4/9
We present a simple scheme using two identical cross-phase modulation processes in decoherence environment to generate superpositions of two coherent states with the opposite phases, which are known a...
Eavesdropping of two-way coherent-state quantum cryptography via Gaussian quantum cloning machines

2010/10/15
Quantized nonlinear lattice models are considered for two different classes, boson and
fermionic ones. The quantum discrete nonlinear Schr¨odinger model (DNLS) is our main
objective, but its so call...
