Quantum machine naked eye." Quantum machine 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. However, as highlighted by the Schrödinger's cat thought experiment, quantum effects are not readily observable in large-scale objects. 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. Researchers created the first quantum machine in
Dead or Alive 2 remake of "DOA" and "DOA2" for the Xbox with a greatly improved graphics engine. As it was created after "Dead or Alive 3", it takes elements and mechanics from both its original iteration and successor. The action of 3D-axis movement is as free-formatted as "DOA3", and Hitomi, as well as Tengu are now playable characters (albeit outside story mode), but other elements have been kept intact from "DOA2". The biggest set of changes instituted in "Dead or Alive Ultimate" are online play over Xbox Live and the inclusion of slopes, which are a type of environmental hazard. Dead or Alive
