...despite the headline saying they did

https://time.com/4854718/quantum-entanglement-teleport-space/? 

Some stories say they teleported an electron. This one says photon. Regardless, it was the state of the particle that was teleported, not the particle itself.

Is that even an accurate statement ?
the 'state' of a particle is information; as such it cannot be 'teleported', but must obey locality.

That's very confusing. How can you teleport the state and not the particle, is that even teleportation?

Are they using hyperbole to make it sound more exciting?

Locality is not violated. The information transfer happens no faster than c

If e.g. an electron is spin up, you transmit the information that it's spin up and make an electron at the destination be spin up.

But you can do this without knowing the state of the particle.

"The information transfer happens no faster than c"

Exactly !
 so why call it 'teleportation', which implies instantaneous transfer across undefined distance ?

Click bait and ad revenue 

My post was in reply to Swansont who claimed that just the 'state' was teleported, not the particle.
The 'state' is information, and as such, cannot be teleported.
( at least according to my understanding of what 'teleportation' means; or am I being pedantic ? )

Wow...so you're saying they've done it more than once?

Now I'll read the OP and the article...

So they entangled two particles while they were hundreds of miles apart?

Mind blowing!

But hey... it's from 2017! Why address this now?

Physicists are notorious for exploiting this.

It showed up in my twitter TL. Didn't notice it was from 2017; I thought I was getting ahead of the curve in pushing back on the dodgy pop-sci headline.
