Image illustrating traversable local wormhole. Space is represented horizontally. Time runs vertically, upwards. The two quantum objects, one on either side, start off at the bottom. The complex quantum object to be counterported is the one on the right. As time elapses, the local wormhole gradually folds, then unfolds, space—allowing the object on the right to be reconstituted across. The saturation of the colour red between the two objects represents the extent to which space is folded. The orange and the green vertical lines, corresponding to two local journeys in observable spacetime, indicate that no detectable information carriers were exchanged.
