Information was exchanged using an array of ions, isolated in magnetic traps within the prism. When the prism was activated and the universal wave function split into two branches, these ions remained in a state of coherent superposition, balanced on a knife’s edge and accessible to either branch. Each ion could be used to send a single bit of information, a yes or a no, from one branch to the other. The act of reading that yes/no caused the ion to decohere, permanently knocking it off the knife’s edge and onto one side. To send another bit, you needed another ion. With an array of ions, you
