In the quantum world, the future predicts the past. Playing a guessing game with a superconducting circuit called a qubit, a physicist has discovered a way to narrow the odds of correctly guessing the state of a two-state system. By combining information about the qubit’s evolution after a target time with information about its evolution up to that time, the lab was able to narrow the odds from 50-50 to 90-10.
