Scientists just teleported an object into Earth's orbit for the first time (2017)

- jrgd 6y agoold click bait and i fell for it! thanks
- marwan-nwh 6y agomy apologies
- rwoerz 6y agoWould that work with an object of the size and mass of, say, a mother in law? Just curious...

- DJBunnies 6y agoIs a photon an object?
- NiceWayToDoIT 6y agoCan someone please explain how is quantum teleportation different than, transmitting information about object and then making another object behave the same way as the first one?
- jrgd 6y agoit feels like the core advantage over current information transportation is for inter planetary communication.
- NiceWayToDoIT 6y agoI still do not understand, as they do not carry Qubits, but they use laser to transmit information, why not use the laser in the first place to transmit information?
- jrgd 6y agocouldn’t find a reference to laser in the article; where did you read this?
- joshuaissac 6y agoLasers are mentioned in the linked arXiv paper: https://arxiv.org/abs/1707.00934 https://arxiv.org/abs/1707.00934
- NiceWayToDoIT 6y agoI would like to know what kind of interesting mind downvotes question?!
- monadic3 6y agoThe only benefit that quantum entanglement provides is the agreement of a key over a distance. Communication itself would be "normal", i.e. EM.

- SuperCuber 6y agoCan someone ELI5 why this doesn't break the "information can't move faster than the speed of light" rule?
- boxed 6y agoBecause you can't read the data without a quantum decryption key, which you need to transmit the normal way. This is the same as with tunneling.
- jrootabega 6y agoThe article is essentially nonsense. Entanglement cannot transmit arbitrary information. At best, it can provide remote synchronization. E.g. my photon collapsed to a 0, therefore I know my partner's photon is a 1. We will execute Playbook A. Also, nothing teleported. The photon in question was sent via a laser.
- masteranza 6y agoExactly. ELI5 is that quantum teleportation is (sadly) a marketing phrase. It is 2020 and such phrases as "teleported an object" are simply a mischief.
- lisper 6y agoBecause the quantum teleportation protocol requires the transmission of classical information in order to complete it. It's really a bogus label. Nothing physical is being teleported. It's just a way of using two classical bits to move a qbit from A to B.
- psychoslave 6y agoInformation is the result of an interpretation, not the data you try to share with a distant interpreter. As current widely admitted interpretation of red shift tell us, there are star moving away from us at a pace faster than speed of light, due to time-space inflation. And finally, one possible interpretation of quantic intrication is that the change reflected on two distant objects is that there are actually the same object on some dimension which we can't grab with our tools. None of these invalidate the idea of a maximum speed for all objects along a given dimension of a stable space.
