Full-held, retrorehective holographic imaging through turbid media has been achieved using a photorefractive polymer composite as a coherence gate The photorefractive devices used, are based on PVK and TNFDM which is doped with the chromophore l-(2 -ethylhexyloxy)-2,5-dimethyl-4-(4 -nitrophenylazo)benzene. There is certain evidence that TNFDM interacts with chromophores by complexation. ...

The intensity autocorrelation measurement is comparable to all of the spectroscopic experunents discussed in the sections that follow because it exploits the use of a variably delayed, gating pulse in the measurement. In the autocorrelation experiment, the gating pulse is just a replica of the time-fixed pulse. In the spectroscopic experiments, the gating pulse is used to mterrogate the populations and coherences established by the time-fixed pulse. 

Single atomic ions confined in radio frequency traps and cooled by laser beams (Figure 7.4a) formed the basis for the first proposal of a CNOT quantum gate with an explicit physical system [14]. The first experimental realization of a CNOT quantum gate was in fact demonstrated on a system inspired by this scheme [37]. In this proposal, two internal electronic states of alkaline-earth or transition metal ions (e.g. Ba2+ or Yb3+) define the qubit basis. These states have excellent coherence properties, with T2 and T2 in the range of seconds [15]. Each qubit can be... 

X 10 cm s has been attributed to carrier confinement and coherence [216-218]. In addition, graphene has shown a strong ambipolar electric field, i.e., charge carriers can be alternated between holes and electrons depending upon the nature of the gate voltage [183].

SLI is not specific to molecular eigenstates, but universal to the superposition of any eigenstates in a variety of quantum systems. It is thus expected as a new tool for quantum logic gates not only in MEIP but also for other systems such as atoms, ions, and quantum dots. SLI also provides a new method to manipulate WPs with fs laser pulses in general applications of coherent control. 

There are many systems of different complexity ranging from diatomics to biomolecules (the sodium dimer, oxazine dye molecules, the reaction center of purple bacteria, the photoactive yellow protein, etc.) for which coherent oscillatory responses have been observed in the time and frequency gated (TFG) spontaneous emission (SE) spectra (see, e.g., [1] and references therein). In most cases, these oscillations are characterized by a single well-defined vibrational frequency, It is therefore logical to anticipate that a single optically active mode is responsible for these features, so that the description in terms of few-electronic-states-single-vibrational-mode system Hamiltonian may be appropriate. 

David J. Soderberg, BP Chemicals You mentioned a very coherent and concise set of tools that are used portfolio management, fuzzy front end, and stage gate. Those work very well within a business unit context. They re very focused and allow you to allocate resources.
