The fact that these apparently contradictory attributes are compatible in matter waves and also in light (photons) is hard to understand, but all experimental data point out that this is the case. Waves always have some spatial extension, while one may imagine the elementary, indivisible particles as being “pointlike”. While we cannot dive into mathematical details here, the basic principles shall be sketched. Quantum theory is, so to say, the mathematical formulation of particle–wave duality. Only with quantum theory atomic structure can be understood. Nevertheless, to understand how the colours which surround us come about, one needs some basic knowledge on the smallest parts of matter. If the light of the sun is spread out into different colours by a simple glass prism, the narrow absorption lines cannot be seen. Neon, which gives red colour in a gas discharge, is a colourless gas. The aurora borealis (northern light) is very rare at our latitudes, and to appreciate the colours of cosmic objects, powerful telescopes are necessary. Neon signs (or other gas discharge tubes) as used for advertising, sodium or mercury vapour lamps show atomic emission the colours of fireworks are due to it. Some remarks are made about the nature of irreversibility in this exactly soluble and loss-free model.Light emitted or absorbed by single atoms contributes only very little to the colours of our surroundings. We give analytic formulas for the collapse function, for both of the revival times, and for the envelope of the revival maxima. Unusual features found in the temporal behavior of this lossless model problem are 'collapse,' i.e., episodic nonexponential damping of both the atomic inversion and dipole moment, and two kinds of 'revival' or partial recorrelation, in the dynamic evolution, during which the initial state is nearly recovered. All of the results are obtained without semiclassical or decorrelation approximations. The atomic dipole-dipole correlation function is calculated. We give new long-time numerical and closed-form approximate analytic solutions for the expectation values of the atomic dipole moment and the difference in population of the two atomic levels in the rotating wave approximation. The model consists of a single two-level atom or spin interacting with a single mode of the quantized radiation field in the dipole approximation, the mode being initially in an arbitrary coherent state of excitation. We describe the temporal behavior of the dynamic elements of an exactly soluble quantum model. However, on measuring the intracavity field state tomography, measurements confirm such a matching, that is, calibration is well documented. Within various surroundings of Kerr materials of different Kerr constants, that is an additional source of an effective dephasing, spectrum rapidly oscillates and so also entanglement that shows rapid Rabi oscillations during its fast degradation depending on the detuning width. Once the pumping starts, a partial dephasing is encouraged, thus, the spectrum is inversely but slightly affected, nevertheless, matching remains highly closed.

The most striking feature realized is that, on high detuned interaction, a full matching of these phenomena outputs can be achieved regardless of the absence or presence or pumping. We show that, a measurement of the spectrum outputs represent a highly effective key calibration for entanglement attributes, where complete time dynamics may be predicted with a high considerable accuracy.

Cooperation and decoherence as well as the statistics of the emitted radiation are discussed and analyzed in terms of the other phenomena. Various characteristics are monitored while observations are theoretically documented-via tracing the field state tomography-and experimentally calibrated. The system Hamiltonian that is a nonlinear and a time-dependent system, is diagonalized and the time evolution unitary operator in an exact form is derived. The qubits are initially maximally-entangled while they penetrate a detuned, single-photon and coherent cavity embedded in nonlinear media. Cooperative atomic emission spectrum as a key probe of entanglement dynamics of an independent and a classically-pumped qubits pair is showed and investigated.
