Physicists can predict the jumps of Schrödinger’s cat (and finally save it)

  • The paradox of Schrödinger's cat refers to a black cat enclosed in a box sealed with a radioactive source and a poison that will activate when the radioactive substance disintegrates.
  • According to the theory of the superposition of states of quantum mechanics, until someone opens the box the cat is alive or dead.
  • When you open the box and observe the cat, a quantum jump occurs in a non-continuous way and its quantum state changes suddenly and randomly and the cat will be alive or dead, according to Niels Bohr.
  • In relation to this quantum argument, an experiment described in the journal Nature reveals that quantum jumps are continuous and predictable, and the cat can be saved.
  • This discovery opens new perspectives to control quantum information and can be useful in the design of quantum computers.
