Red, green and blue are known as “three primary colors” of lights and when these all three colors are mixed the result is white. The colors that are pair of opposite side in the right “color circle” are called “complementary colors”. For example, red and cyan, green and magenta and blue and yellow are the pairs of complementary colors. When these two complementary colors are mixed together, it also makes white.

The colors which yields white by adding all three primary colors are called additive colors, e.g. the three primary colors of lights. Conversely, the colors which yields black by adding all three primary colors are called subtractive colors.

In quantum computing, a qubit (/ˈkjuːbɪt/) or quantum bit (sometimes qbit^{[citation needed]}) is the basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the peculiarity of quantum mechanics. Examples include: the spin of the electron in which the two levels can be taken as spin up and spin down; or the polarization of a single photon in which the two states can be taken to be the vertical polarization and the horizontal polarization. In a classical system, a bit would have to be in one state or the other. However, quantum mechanics allows the qubit to be in a coherent superposition of both states simultaneously, a property which is fundamental to quantum mechanics and quantum computing.

In physics, a quantum (plural quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. The fundamental notion that a physical property can be “quantized” is referred to as “the hypothesis of quantization“.^[1] This means that the magnitude of the physical property can take on only discrete values consisting of integer multiples of one quantum.

For example, a photon is a single quantum of light (or of any other form of electromagnetic radiation). Similarly, the energy of an electron bound within an atom is quantized and can exist only in certain discrete values. (Atoms and matter in general are stable because electrons can exist only at discrete energy levels within an atom.) Quantization is one of the foundations of the much broader physics of quantum mechanics. Quantization of energy and its influence on how energy and matter interact (quantum electrodynamics) is part of the fundamental framework for understanding and describing nature.

In physics, quantization (in British English quantisation) is the process of transition from a classical understanding of physical phenomena to a newer understanding known as quantum mechanics. It is a procedure for constructing a quantum field theory starting from a classical field theory. This is a generalization of the procedure for building quantum mechanics from classical mechanics. Also related is field quantization, as in the “quantization of the electromagnetic field“, referring to photons as field “quanta” (for instance as light quanta). This procedure is basic to theories of particle physics, nuclear physics, condensed matter physics, and quantum optics.
