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

The fighting series have received positive reviews, with "Dead or Alive 2" having the highest ratings out of the numbered games, and "Dead or Alive 5" having the lowest except its "Plus" version for the Vita. Dead or Alive (franchise) The "Dead or Alive" series focuses on fast-paced gameplay in a three-dimensional playing field. Like other modern fighting games that attempt to emulate real life martial arts, "DOA"'s input system is designed so controls correspond game
