Once we become a class 2 civilization, we will need to have quantum entangled communications, however, as I said, we are quite some time from it. The best we can achieve with current technology is fiber/light based communications.

In regards to having sub 5ms ping times to Google, a ping request is only 4-16 bytes in length, whereas, a 1920x1080p image (uncompressed) is roughly 36 million bytes.


And its a stream that only need to travel one way. That image do not have to be sent serial, it is very much open for sending in multiple streams, so it would be very good at maximizing bandwidth usage.

I'm just seeing that there is a powerfull Note 4 in one end and a powerfull PC in the other end, and with open API on both ends, its a hell of a lot closer to be a wireless "screen" for my PC then the cabled versions. If someone down the road make a dedicated wireless VR headset, thats great. But this is hereish nowish.

Correct about google, although that's exactly why we are developing photonic routing and signal processing. In addition to potentially near 0 latency, photonic routers can achieve the bandwidth of several Tb per channel. That is already possible with hybrid solutions [http://compass-eos.com/product/overview-2/] and will only get better with all-optical routing.

As for quantum entanglement, you are just wrong. Quantum entanglement does not in fact transfer information faster than the speed of light in any sense. Don't read rubbish websites, read wikipedia: http://en.wikipedia.org/wiki/Quantum_teleportation The explanation there is a bit simplified and not totally correct, but it's very close to what's actually happening.

Also have a look at the abstract of the actual paper you are trying to cite: http://www.sciencemag.org/content/345/6196/532.abstract
It says "We prepare the teleporter through photon-mediated heralded entanglement between two distant electron spins and subsequently encode the source qubit in a single nuclear spin." Photons travel at the speed of light, and the photonic interconnect is necessary for quantum teleportation.

So quantum communication does not have any speed-related advantages over classical communication. The advantages of quantum communication are (1) security through quantum key distribution [http://en.wikipedia.org/wiki/Quantum_key_distribution], and (2) being able to connect quantum computers [http://en.wikipedia.org/wiki/Quantum_computer].

The basic principle is pretty easy. Quantum entanglement does technically "transmit" information at more than the speed of light, but that information is unavoidably random. Simply knowing the state of the electrons breaks the entanglement, so trying to stick your own information in there stops it from working before you even start.

Basically you and someone far away could get the exact same noise pattern at the same instant (theoretically, if we solve a whole lot of other problems), but that's it, anything else is impossible under the basic rules of quantum mechanics just as perpetual motion is impossible under the conservation of energy. If there is a way to transmit man-made information faster than light, its something else.

How does the Gear VR adjust for IPD?
There is a wheel at the top of the unit to adjust focus, but what about IPD?
