Quantum machine

From Wikipedia, the free encyclopedia

A quantum machine is a human-made device whose collective motion follows the laws of quantum mechanics. The idea that macroscopic objects may follow the laws of quantum mechanics dates back to the advent of quantum mechanics in the early 20th century.[1][2] However, as highlighted by the Schrödinger's cat thought experiment, quantum effects are not readily observable in large-scale objects.[citation needed] Consequently, quantum states of motion have only been observed in special circumstances at extremely low temperatures. The fragility of quantum effects in macroscopic objects may arise from rapid quantum decoherence.[3] Researchers created the first quantum machine in 2009, and the achievement was named the "Breakthrough of the Year" by Science in 2010.
