Quantum finance is an interdisciplinary research field, applying theories and methods developed by quantum physicists and economists in order to solve problems in finance. It is a branch of econophysics. Quantum computing is now being used for a number of financial applications, including fraud detection, stock price prediction, portfolio ...
Quantum Clustering (QC) is a class of data-clustering algorithms that use conceptual and mathematical tools from quantum mechanics. QC belongs to the family of density-based clustering algorithms, where clusters are defined by regions of higher density of data points.

[ 2 ] [ 3 ] [ 4 ] Their products are used by enterprises, media and entertainment companies, government agencies, big data companies, and life ...
Infinite Dimensional Analysis, Quantum Probability and Related Topics is a quarterly peer-reviewed scientific journal published since 1998 by World Scientific. It covers the development of infinite dimensional analysis , quantum probability , and their applications to classical probability and other areas of physics .
Quantum statistical mechanics is statistical mechanics applied to quantum mechanical systems.In quantum mechanics a statistical ensemble (probability distribution over possible quantum states) is described by a density operator S, which is a non-negative, self-adjoint, trace-class operator of trace 1 on the Hilbert space H describing the quantum system.
Quantum chemistry computer programs are used in computational chemistry to implement the methods of quantum chemistry. Most include the Hartree–Fock (HF) and some post-Hartree–Fock methods. They may also include density functional theory (DFT), molecular mechanics or semi-empirical quantum chemistry methods .
In quantum computing, a quantum algorithm is an algorithm that runs on a realistic model of quantum computation, the most commonly used model being the quantum circuit model of computation. [ 1 ] [ 2 ] A classical (or non-quantum) algorithm is a finite sequence of instructions, or a step-by-step procedure for solving a problem, where each step ...
A reversible gate is a reversible function on n-bit data that returns n-bit data, where an n-bit data is a string of bits x 1,x 2, ...,x n of length n. The set of n-bit data is the space {0,1} n, which consists of 2 n strings of 0's and 1's. More precisely: an n-bit reversible gate is a bijective mapping f from the set {0,1} n of n-bit data ...
