In parallel with the study of the control of atomic and molecular systems, "quantum engineering" of light itself has also been extensively investigated [114, 131, 132]. These studies have been aided by the availability of ultracold systems and advances in solid-state electronics. In particular, numerous nonclassical light states with squeezed fluctuations of observables have been constructed, and general methods for their preparation have been developed [133-136]. 

The second quantum revolution as lliis continuing further development of quantum physical thinking is called by Alain Aspect, one of the pioneers in this field one expects a deeper imderstanding of quantum physics itself but also applications in engineering. There is already the term quantum engineering which describes scientific activities to apply particle wave duality or entanglement for practical purposes, for example, nano-machines, quantum computers, etc. [8, 9] (Fig. 6.1).

Molecular modeling has evolved as a synthesis of techniques from a number of disciplines—organic chemistry, medicinal chemistry, physical chemistry, chemical physics, computer science, mathematics, and statistics. With the development of quantum mechanics (1,2) ia the early 1900s, the laws of physics necessary to relate molecular electronic stmcture to observable properties were defined. In a confluence of related developments, engineering and the national defense both played roles ia the development of computing machinery itself ia the United States (3). This evolution had a direct impact on computing ia chemistry, as the newly developed devices could be appHed to problems ia chemistry, permitting solutions to problems previously considered intractable. 

The computer simulation of models for condensed matter systems has become an important investigative tool in both fundamental and engineering research [149-153] for reviews on MC studies of surface phenomena see Refs. 154, 155. For the reahstic modeling of real materials at low temperatures it is essential to take quantum degrees of freedom into account. Although much progress has been achieved on this topic [156-166], computer simulation of quantum systems still lags behind the development in the field of classical systems. This holds particularly for the determination of dynamical information, which was not possible until recently [167-176]. 

As I mentioned above, it is conventional in many engineering applications to seek to rewrite basic equations in dimensionless form. This also applies in quantum-mechanical applications. For example, consider the time-independent electronic Schrodinger equation for a hydrogen atom... 

While hydrogen engines have some advantages over natural-gas engines, the hydrogen fuel cell offers a true quantum leap in both emissions and efficiency. 

It is common that mechanochemical degradation involves scission of the macromolecule, so one basic question would be to inquire about the level of stress necessary to separate two chemical moieties which have been attached by a covalent bond. Besides the academic interest, the breaking strength of a covalent bond is associated with the ultimate properties of engineering materials and has attracted considerable attention since the beginnings of quantum chemistry.

This cautionary remark expressed, we may conclude this section giving a positive answer to our question. Quantum chemistry, in the version cultivated by group II, represents an important factor in the growth of chemistry, and constitute one of the cornerstones of molecular engineering, or similar activities addressed to plan, and to produce, new substances, new materials endowed with special properties.

Starting from pure academic knowledge, Quantum Chemistry has gained the rank of full partner in most chemical research carried out today, from organic chemistry to solid state chemistry, from biology to material sciences, from astrophysics to chemical engineering.
