Human teleportation brings up MASSIVE problems such as:

Teleportation is breaking one down to quanta - that is killing you — then sending those quanta elsewhere. Are you dead and a copy of you now revived? Does your soul follow?

Worse — why not just repeat the reproduction side endlessly? There could be millions of perfect clones of you. And if you did do any have a soul?

This isn’t as bad as the “does Data have a soul” question but it is a valid line of questioning.

This is the equivalent to the Transporter Operator saying, “I’ve got a lock on you”.

99.9% of the job remains undone.

So how do they know it’s the same photon?

Do they hang a chain on its little photon neck with a tag that says “Hi! I’m the photon from Earth!”?

What if another photon that was closer just sort of hitchhiked onto the beam to get inside the nice warm space station?

How do you teleport a bunch of particles?

How is this teleportation? From the description, they shot a beam of light at it, and the photoreceptor received it.

From the article:

One of the most difficult to grasp aspects of quantum physics is how observing a quantum particle forces the particle's state to change.

This is known as the observer effect, and it is the result of the instruments necessary to measure the state of very small objects.

It's not the result of the instruments. It appears to be a result of the knowledge of the state of the photon. The classic double-slit experiment can be run with the photon detectors hooked up and running but not recording the data and the interference patterns appear - but as soon as the data is recorded (or observed) the interference pattern disappears.

To really get into the spooky stuff check out the Delayed Choice Quantum Eraser experiment where the interference pattern can be shown to manifest or not depending on a choice made by an instrument throwing out random choices at a time after the photons should already either have taken an unknown path or a known path and hence produced the interference pattern or produced the two bright spots. Way cool!

Youtube has lots of videos on the delayed choice experiment.

Delayed Choice Quantum Eraser

If you're into this stuff, check out Tom Wheeler's video presentation where he describes using a piece of film that will be developed at a time after the choice of whether or not to "know" the paths of the photons is made and guess what appears or doesn't appear on the developed film depending on what choice was made?

If you really want to get out there look into Jack Sarfatti's explanation of this effect (hint: retro-causal quantum interaction, ie. causing an action to happen or not happen in the past by a choice made in the present!)

Personally, this stuff is way too spooky for me. I like Einstein's opinion that "God doesn't play dice with the universe."

Micius sounds Latin, not Chinese. What was his real name?

What a crap article.

You have to read between the lines to try to figure out what if anything happened.

The best I can figure out is that they started with a pair of entangled photons, kept one on earth and launched the other up in space and then showed that they were still entangled.

That’s not exactly teleportation. The photon on earth is still on earth.

[Arlis]

Hasn’t the sun been “teleporting” trillions of photons to earth for billions of years?

So what’s new about that?

I teleport photons every time I use a flashlight!

[Wuli]

This is not true “teleportation”.

At the quantum state it is already known and accepted that distance, as we know it, does not matter in the case of the “observer” results of witnessing items at the quantum state.

“Distance” between two locations is not “distance” to certain particles in the quantum state. The “observation” points may have been “far apart” at the human level (and level of their tools) of observation, but nothing was “teleported” - “moved”.

[DungeonMaster]

Shining a flashlight = teleporting millions of photons.
