Quantum State Space
In physics, a quantum state space is an abstract space in which different "positions" represent not literal locations, but rather quantum states of some physical system. It is the quantum analog of the phase space of classical mechanics. Relative to Hilbert space In quantum mechanics a state space is a Hilbert_space#Separable_spaces, separable complex number, complex Hilbert space. The dimension (vector space), dimension of this Hilbert space depends on the system we choose to describe. The different states that could come out of any particular measurement form an orthonormal basis, so any quantum state, state vector in the state space can be written as a linear combination of these basis vectors. Having a nonzero component along multiple dimensions is called a Quantum superposition, superposition. In the Mathematical formulation of quantum mechanics, formalism of quantum mechanics these quantum state, state vectors are often written using Paul Dirac, Dirac's compact bra–ket ...

Physics
Physics is the scientific study of matter, its Elementary particle, fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." It is one of the most fundamental scientific disciplines. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (...) You will come to see physics as a towering achievement of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
