second quantum number
21Quantum mechanics — For a generally accessible and less technical introduction to the topic, see Introduction to quantum mechanics. Quantum mechanics …
22Second law of thermodynamics — The second law of thermodynamics is an expression of the universal law of increasing entropy, stating that the entropy of an isolated system which is not in equilibrium will tend to increase over time, approaching a maximum value at… …
23Quantum computer — A quantum computer is a device for computation that makes direct use of distinctively quantum mechanical phenomena, such as superposition and entanglement, to perform operations on data. In a classical (or conventional) computer, information is… …
24Quantum of Solace — For other uses, see Quantum of Solace (disambiguation). Quantum of Solace Theatrical release p …
25Quantum channel — In quantum information theory, a quantum channel is a communication channel which can transmit quantum information, as well as classical information. An example of quantum information is the state of a qubit. An example of classical information… …
26Quantum critical point — A quantum critical point is a special class of continuous phase transition that takes place at the absolute zero of temperature, typically in a material where the phase transition temperature has been driven to zero by the application of a… …
27Quantum vortex — In physics, a quantum vortex is a topological defect exhibited in superfluids and superconductors. The existence of these quantum vortices were independently predicted by Richard Feynman and Alexei Alexeyevich Abrikosov in the 1950s. They were… …
28quantum computer — ▪ computer science device that employs properties described by quantum mechanics to enhance computations. As early as 1959 the American physicist and Nobel laureate Richard Feynman (Feynman, Richard P.) noted that, as electronic… …
29Quantum mind–body problem — The quantum mind–body problem refers to the philosophical discussions of the mind–body problem in the context of quantum mechanics. Since quantum mechanics involves quantum superpositions, which are not perceived by observers, some… …
30Quantum cohomology — In mathematics, specifically in symplectic topology and algebraic geometry, a quantum cohomology ring is an extension of the ordinary cohomology ring of a closed symplectic manifold. It comes in two versions, called small and big; in general, the …
