Quantum States

In Quantum Physics, Quantum State refers to the state of a Quantum system. Quantum system can be either pure or mixed. A pure Quantum state is represented by a vector, called a state vector, in a Hilbert space. If this Hilbert Space is represented as a function space, then its elements are called Wave functions. when  pairs or groups of particles are generated or interact in ways such that the Quantum state of each particle cannot be described independently instead, a Quantum state may be given for the system as a whole then the phenomenon Entanglement occurs. Quantum vacuum zero-point energy is the lowest possible energy that a Quantum mechanical physical system may have. All Quantum mechanical systems undergo fluctuations even in their ground state and have associated zero-point energy, a consequence of their wave-like nature. It is the energy of its ground state. The symmetry of a particle state is determined by spin. At the same time, the state dynamics of quantum systems determines the entropy dynamics, as a characteristic of the order evolution. Recently, has been found that, while in a molecular system the entropy always increases (principle 2 of thermodynamics), in a matter-field system the entropy may decrease, suggesting interesting applications, such as environmental heat conversion into usable energy.
