Quantum-optical states in finite-dimensional Hilbert space. II. State generation
Wieslaw Leonski, Adam Miranowicz
In the second part of our review (for the first part see quant-ph/0108080), we discuss a physical model for generation of "truncated" coherent and squeezed states in finite-dimensi…
Maximum entanglement of quantum-dot systems with single excitation in the spin van der Waals model
A. Miranowicz, S. K. Ozdemir, M. Koashi +2
Time evolution of entanglement of N quantum dots is analyzed within the spin-1/2 van der Waals (or Lipkin-Meshkov-Glick) XY model. It is shown that, for a single dot initially exci…
Quantum, classical and semiclassical analyses of photon statistics in harmonic generation
Jiri Bajer, Adam Miranowicz
In this review, we compare different descriptions of photon-number statistics in harmonic generation processes within quantum, classical and semiclassical approaches. First, we stu…
Quantum-optical states in finite-dimensional Hilbert space. I. General formalism
Adam Miranowicz, Wieslaw Leonski, Nobuyuki Imoto
The interest in quantum-optical states confined in finite-dimensional Hilbert spaces has recently been stimulated by the progress in quantum computing, quantum-optical state prepar…
Wehrl information entropy and phase distributions of Schrodinger cat and cat-like states
A. Miranowicz, J. Bajer, M. R. B. Wahiddin +1
The Wehrl information entropy and its phase density, the so-called Wehrl phase distribution, are applied to describe Schrödinger cat and cat-like (kitten) states. The advantages of…
Quantum versus classical descriptions of sub-Poissonian light generation in three-wave mixing
Jiri Bajer, Adam Miranowicz
Sub-Poissonian light generation in the non-degenerate three-wave mixing is studied numerically and analytically within quantum and classical approaches. Husimi Q-functions and thei…
