After stumbling upon this recent news article: Information teleported between two computer chips for the first time (which references a "Nature Physics" publication Chip-to-chip quantum teleportation and multi-photon entanglement in silicon)...
...with quantum teleportation, information appears to break that speed limit
Harnessing this phenomenon could clearly be beneficial, and the new study helps bring that closer to reality. The team generated pairs of entangled photons on the chips, and then made a quantum measurement of one. This observation changes the state of the photon, and those changes are then instantly applied to the partner photon in the other chip.
... I've been wondering what this specific break-through means for the state of quantum teleportation, if anything.
The quotes above would appear to imply that information can potentially be transported and used instantly, faster than the speed of light. Is that accurate though? My understanding was that because of its dependency on classical communication, quantum teleportation won't allow for faster-than-light communication in practice. Has that changed?
