Wigner's friend and continuous time evolution of the state of a closed system and the probabilistic, discontinuous collapse of the state of a system upon measurement. Wigner's friend is therefore directly linked to the measurement problem in quantum mechanics with its famous Schrödinger's cat paradox. The thought experiment posits a friend of Wigner in a laboratory and lets him perform a quantum measurement on a physical system (this could be a spin system or also Schrödinger's cat). This system is assumed to be in a superposition of two distinct states, say, state 0 and state 1 (or "dead" and "alive", in the
Dead or Alive 5 of these reboots. More accurately, "DOA5" is a rebirth." "X360" ranked "Dead or Alive 5" as the third most sexy game coming over in 2012. The full version of "Dead or Alive 5" was met with a generally positive critical response. Reviewers typically praised the game's graphics and animation, as well as the spectactularity of the fights and their deeper gameplay mechanics. However, several reviews criticized the story mode and aspects of its online features. Some of the reviewers also expressed disappointment with what they thought was Team Ninja's failure to innovate enough as compared to previous titles in the
