The term "wave function" is typically used for a different mathematical representation of the quantum state, one that uses spatial coordinates also called the "position representation". [9]: 324 When the wave function representation is used, the "reduction" is called "wave function collapse".
Model synthesis (also wave function collapse or 'wfc') is a family of constraint-solving algorithms commonly used in procedural generation, especially in the video game industry. Some video games known to have utilized variants of the algorithm include Bad North , Townscaper , and Caves of Qud .
The most widely studied among the dynamical reduction (also known as collapse) models is the CSL model. [1] [2] [3] Building on the Ghirardi-Rimini-Weber model, [4] the CSL model describes the collapse of the wave function as occurring continuously in time, in contrast to the Ghirardi-Rimini-Weber model. Some of the key features of the model ...
Philip Pearle's 1976 paper pioneered the quantum nonlinear stochastic equations to model the collapse of the wave function in a dynamical way; [4]: 477 [5] [6] [7] this formalism was later used for the CSL model. However, these models lacked the character of “universality” of the dynamics, i.e. its applicability to an arbitrary physical ...
In quantum mechanics, einselections, short for "environment-induced superselection", is a name coined by Wojciech H. Zurek [1] for a process which is claimed to explain the appearance of wavefunction collapse and the emergence of classical descriptions of reality from quantum descriptions.
Penrose's idea is a type of objective collapse theory. For these theories, the wavefunction is a physical wave, which experiences wave function collapse as a physical process, with observers not having any special role. Penrose theorises that the wave function cannot be sustained in superposition beyond a certain energy difference between the ...
[1] [2] Later, following a different line of reasoning, Roger Penrose arrived at an estimation for the collapse time of a superposition due to gravitational effects, which is the same (within an unimportant numerical factor) as that found by Diósi, hence the name Diósi–Penrose model.
[12] [13] In these schools of thought, wave functions may be regarded as statistical information about a quantum system, and wave function collapse is the updating of that information in response to new data. [14] [15] Exactly how to understand this process remains a topic of dispute. [16] Bohr discussed his views in a 1947 letter to Pauli. [17]
