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 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".
Similarly, one can also quantify the minimum collapse strength to solve the measurement problem at the macroscopic level. Specifically, an estimate [ 6 ] can be obtained by requiring that a superposition of a single-layered graphene disk of radius ≃ 10 − 5 {\displaystyle \simeq 10^{-5}} m collapses in less than ≃ 10 − 2 {\displaystyle ...
For composite systems, the collapse on each constituent causes the collapse of the center of mass wave functions. Continuous spontaneous localization (CSL) model : [ 10 ] The Schrödinger equation is supplemented with a nonlinear and stochastic diffusion process driven by a suitably chosen universal noise coupled to the mass-density of the ...
The Diósi–Penrose model was introduced as a possible solution to the measurement problem, where the wave function collapse is related to gravity.The model was first suggested by Lajos Diósi when studying how possible gravitational fluctuations may affect the dynamics of quantum systems.
[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]
If measurements are made periodically, with some finite interval between each one, at each measurement, the wave function collapses to an eigenstate of the measurement operator. Between the measurements, the system evolves away from this eigenstate into a superposition state of the states A {\displaystyle A} and B {\displaystyle B} .
A poll was conducted at a quantum mechanics conference in 2011 using 33 participants (including physicists, mathematicians, and philosophers). Researchers found that 6% of participants (2 of the 33) indicated that they believed the observer "plays a distinguished physical role (e.g., wave-function collapse by consciousness)".
