Optimal design and quantum benchmarks for coherent state amplifiers
Optimal design quantum benchmarks coherent state amplifiers
2016/1/23
We establish the ultimate quantum limits to the amplification of an unknown coherent state, both in the deterministic and probabilistic case, investigating the realistic scenario where the expected ph...
Vector coherent state representations and their inner products
Vector coherent state representations their inner products Mathematical Physics
2012/7/11
Several advances have extended the power and versatility of coherent state theory to the extent that it has become a vital tool in the representation theory of Lie groups and their Lie algebras. Repre...
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 between an electron- and nuclear spin in 15N@C60
Coherent state transfer electron- and nuclear spin
2010/11/25
Electron spin qubits in molecular systems o er high reproducibility and the ability to self assemble into larger architectures. However, interactions between neighbouring qubits are `always-on' and al...
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
2010/10/19
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...
The Coulomb solution as a coherent state of unphysical photons
Coulomb solution coherent state unphysical photons
2010/3/17
In the context of the problem of what micro-states are responsible for the entropy of black holes, we consider as a physical toy model the electromagnetic Coulomb solution. By quantizing the electroma...
Scheme for generating coherent state superpositions with realistic cross-Kerr nonlinearity
generating coherent state 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
two-way coherent-state quantum cryptography Gaussian quantum cloning machines
2010/4/9
We consider one of the quantum key distribution protocols recently introduced in Ref. [Pirandola et al., Nature Physics 4, 726 (2008)]. This protocol consists in a two-way quantum communication betwee...
