(or quantum trit), is a unit of quantum information that is realized by a 3-level quantum system, that may be in a superposition of three mutually orthogonal quantum states. [60] The qutrit is analogous to the classical radix -3 trit , just as the qubit , a quantum system described by a superposition of two orthogonal states, is analogous to ...
A common example of quantum numbers is the possible state of an electron in a central potential: (,,,), which corresponds to the eigenstate of observables (in terms of ), (magnitude of angular momentum), (angular momentum in -direction), and .
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 ...
Possibly the greatest development in the broader digitalization sphere, quantum computers feature the potential to change everything we know about machine-driven calculations, thus auguring very ...

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.
quantum field theory A theoretical framework for constructing quantum mechanical models of subatomic particles in particle physics and quasiparticles in condensed matter physics. quantum gravity quantum mechanics A branch of physics dealing with physical phenomena at microscopic scales, where the action is on the order of the Planck constant.
However, in quantum computing, operations have the ability to introduce phase changes to quantum states. This is the basis for complex interference patterns and quantum entanglement. When a controlled operation, such as a Controlled NOT (CNOT) gate , is applied to two qubits, the phase of the second (target) qubit is conditioned on the state of ...
