    Brukner proposed a way of testing this notion by translating the Wigner's friend scenario into a framework first established by the physicist John Bell in 1964.

    To make matters worse, over time, more heat and more cycles were required to release the extra energy, but even then(unknown until after the accident), pockets of Wigner energy remained in the core.

    Wigner doesn't have access to this fact from the outside, and according to quantum mechanics, must describe the friend and the coin to be in a superposition of all possible outcomes of the experiment.

    Wigner can now in principle verify this superposition using a so-called"interference experiment"- a type of quantum measurement that allows you to unravel the superposition of an entire system, confirming that two objects are entangled.
