Coherent Control of Entanglement with Atomic Ensembles [PDF]

open access: yes, 2011
Quantum networks are composed of quantum nodes which coherently interact by way of quantum channels. They offer powerful capabilities for quantum computation, communication, and metrology. A generic requirement for these realizations is the capability to

DIFFUSION PROCESSES AND COHERENT STATES [PDF]

open access: yesModern Physics Letters B, 1994
It is shown that uncertanity relations, as well as coherent and squeezed states, are structural properties of stochastic processes with Fokker–Planck dynamics. The quantum mechanical coherent and squeezed states are explicitly constructed via Nelson stochastic quantization.

Coherent states and duality [PDF]

open access: yesPhysics Letters A, 2002
We formulate a relation between quantum-mechanical coherent states and complex-differentiable structures on the classical phase space ${\cal C}$ of a finite number of degrees of freedom. Locally-defined coherent states parametrised by the points of ${\cal C}$ exist when there is an almost complex structure on ${\cal C}$.

Fermionic coherent states

open access: yesJournal of Physics A: Mathematical and Theoretical, 2012
The aim of this paper is to give a self-contained and unified presentation of a fermionic coherent state theory with the necessary mathematical details, discussing their definition, properties and some applications. After defining Grassmann algebras, it is possible to get a classical analog for the fermionic degrees of freedom in a quantum system ...

Coherent absorption of N00N states [PDF]

open access: yesConference on Lasers and Electro-Optics, 2016
Recent results in deeply subwavelength thickness films demonstrated coherent control and logical gate operations with both classical and single photon light sources. However, quantum processing and devices typically involve more than one photon and non-trivial input quantum states.

DYNAMICS OF GENERALIZED COHERENT STATES [PDF]

open access: yesModern Physics Letters B, 1995
We show that generalized coherent states follow Schrödinger dynamics in time-dependent potentials. The normalized wave-packets follow a classical evolution without spreading; in turn, the Schrödinger potential depends on the state through the classical trajectory.

Maximally coherent states

open access: yesQuantum Information and Computation, 2015
The relative entropy measure quantifying coherence, a key property of quantum system, is proposed recently. In this note, we firstly investigate structural characterization of maximally coherent states with respect to the relative entropy measure. It is shown that mixed maximally coherent states do not exist and every pure maximally coherent state has ...

Multipartite Spin Coherent States and Spinor States

open access: yes, 2023
Multipartite generalizations of spin coherent states are introduced and analyzed. These are the spin analogues of multimode optical coherent states as used in continuous variable quantum information, but generalized to possess full spin symmetry.
