It would involve a "Space jump" so it would be instantaneous. In HUT (Holographic Universe Theory). All matter particles truly exist at a "higher reality" where there is no SPACE Between them. Our 3D universe is a "Lower reality" construct of our human PERCEPTION.
Just as an EM wave at a given frequency would be seen as RED LIGHT, for example, we perceive waves attributes of MATTER as Positions in a 3 Dimensional space----The "illusion" is so "perfect" because we are perceiving the particles in our bodies in the same way too.
If these wave attributes of matter that determine 3D position could be changed, they would immediately move to the part of 3D space that matched the new settings.-----If we can change these wave attributes for people and space ships we would have INSTANT space jumps---effectively, "teleportation". This HUT theory is how Bohn, Einstein's Protégé, explained Quantum entanglement BTW. As there is no space between particles in the "Higher reality", they are actually in direct contact with each other-----even though in our 3D world, they might appear to be separated by light years.--so when one reacts, so will the other causing the "spooky motion at a distance".
