1. None (the size of a photon). 2. Short & speed of light. 3. Irrelevant, since this is about whether it was actually doable, not about doing it efficiently.

2. Short & speed of light.
3. Irrelevant, since this is about whether it was actually doable, not about doing it efficiently.
4. The output particle is impossible to distinguish from the input one, but it didn't travel from input to output, so... how else would you define "real" teleportation?
- real-teleports 7y agohow else would you define "real" teleportation? As something other than such a ridiculous game of 3 card monte. That's all this has ever been. Put a red marble and a blue marble in a sock, and then close your eyes and withdraw one marble from the sock. Place it in a mitten, and send the mitten to a friend. Then we claim that the person who looks at their marble first has defined the reality of the other by default, and that qualifies as teleportation? Teleportation has been demonstrated as a thought experiment countless times, and this doesn't pass the smell test. The concept of teleportation is instantaneous transportation of physical objects with mass and volume across arbitrarily large distances, seemingly as if stopping time and stepping through a door that connected point A and point B, in order to skip over the effort of transiting real physical distance. This concept may be unrealistic, but we don't squat on antiquated terms like luminiferous ether when we conceptualize quantum foam. There's this academic inertia to opportunistically squat on a word with a loaded meaning, all to gain favor and generate buzz and hype. People desperately want recognition for a contrivance by leaning on a word. They know that using the word "teleportation" to describe something less exciting will provoke magical thinking among outsiders. Since this process cannot produce effects faster than light, it's not even a slight improvement beyond radio or lasers or any form of radiant communication. People don't refer to these efforts appropriately. The objective of these experiments is tamper evidence for quantum communication channels, and nothing more.
