Quantum mechanics is a set of principles that underlie the most fundamentally known description of all physical systems at the sub-microscopic scale (atomic level). What is noteworthy among these principles is the simultaneous behavior of matter and radiation waves and particles ("duality of waves and particles") and probabilistic prediction in case of predictive certainty of classical physics. As a good approximation of quantum physics, classical physics can usually be derived using many particles. Quantum phenomena are therefore of particular relevance for systems with sizes close to the atomic scale, such as molecules, atoms, electrons, protons, and other subatomic particles. There are exceptions to some systems that show quantum mechanical effects on a macroscopic scale, and superfluidity is a well-known example. Quantum theory provides an accurate description of many phenomena that could not be explained so far, such as blackbody radiation and stable electron orbits. It also provides insight into the operation of many different biological systems, including olfactory receptors and protein structures.

Quantum mechanics is also important for understanding how individual atoms form bonds through covalent bonds. Application of quantum mechanics in chemistry is called quantum chemistry. Quantum mechanics can also provide quantitative analysis of ions and covalent processes by clearly indicating which molecules are energetically beneficial for other molecules and the amount of energy involved. Furthermore, most of the calculations done in modern computational chemistry depend on quantum mechanics.

Theoretical chemistry is a field of physicochemistry that calculates the properties of molecules and systems using quantum mechanics and statistical mechanics. As the former usually does, the majority of the activity in quantum chemistry is the computation of the electronic structure of molecules, usually their graphical representation. This study is particularly important for screening potential pharmacological activities of compounds and for determining the mechanism of action of the enzymes.

... We developed a special quantum computer called a quantum simulator that can be used to provide a new perspective of a series of complex quantum processes, from the relationship between quantum mechanics and material properties to new stages of material research. Solve complex real world optimization problems. Harvard University professors Mikhail Lukin and Markus Greiner and MIT's Vladan Vuletic professor developed a special type of quantum computer called a quantum simulator programmed by capturing ultra low temperature enthalpy. The laser atoms are arranged in a specific order and you can perform the calculations required by quantum mechanics

Quantum mental and physical problems refer to the philosophical discussion of mind and body problems in the context of quantum mechanics. Since quantum mechanics involves quantum superposition that the observer can not perceive, some interpretation of quantum mechanics places a conscious observer in a specific position. Founder of quantum mechanics discussed the role of observer, among which Wolfgang Pauli and Werner Heisenberg believed that the observer collapsed. This view is not fully recognized by Niels Bohr and is accused of being mysterious and anti-scientific by Albert Einstein. Poly accepted that word and explained quantum mechanics as modest mysticism.
