Decoherence: New Insights Into Quantum Mechanics
A new theory explaining the quantum-to-classical world transition.
Over the years, scientists have struggled to come up with a satisfactory conclusion about the missing link that bridges the classical (our familiar everyday environment) and quantum worlds, but now researchers from Arizona State University have devised a new theory on how the world we experience through our senses emerges from the ethereal quantum world, the world made of the basic building blocks of matter-atoms.
Innovations Report has more on the theory:
The article describes the transition from quantum to classical world as a “decoherence” process that involves a kind of evolutionary progression somewhat analogous to Charles Darwin’s concept of natural selection. The decoherence concept holds that many quantum states “collapse” into a “broad diaspora,” or dispersion, while interacting with the environment. Through a selection process, other quantum states arrive at a final stable state, called a pointer state, which is “fit enough” (think “survival of the fittest” in Darwinian terms) to be transmitted through the environment without collapsing.
