Electronically erased

摘要

The fate of Schrodinger's cat depends on the particular path of a single electron. If the electron hits the trigger, which opens a bottle of poisonous gas, then the cat dies. If the path misses the trigger, the cat lives. According to quantum mechanics, electrons do not normally follow a definite trajectory. Instead, an electron can trace both paths at the same time. As a result, SchrSdinger's cat is both dead and alive. Quantum mechanics also teaches us that a "which-path" detector-that is, any measurement device that can show where the electron travels-r-forces the electron to choose just one path, thus sealing the cat's destiny.
