Quantum machine 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 2009, and
Dead or Alive Ultimate game mechanics, new game content, online multiplayer capabilities, and the inclusion of Hitomi as a playable character. "Dead or Alive Ultimate" is a compilation game that includes a remade version of "Dead or Alive 2", with re-developed graphics and new stages for the Xbox gaming system. It also includes the original Sega Saturn version of the first "Dead or Alive", with smoothed graphics, but lacks the additional content received in the later-released North American PlayStation version (no Bass or Ayane characters or extra costumes). Both editions include online play. "Dead or Alive Ultimate 1" is essentially identical to its original
