Quantum teleportation brings reliable, super-fast networks a step closer

Scientists at Delft University in the Netherlands have improved the accuracy of a quantum entanglement-based communication channel from one in 100 million in a previous experiment in Maryland to 100 percent today. The information was sent from one solid-state diamond chip to another one, three meters, or ten feet, away.

The results were announced in a recent paper published in ScienceRead more about the research here.

Eventually, this research could lead to almost instantaneous, secure, long-distance communications between quantum computing networks and help make it possible to have a hyper-realistic, lag-free, planet-wide virtual reality metaverse. The communication and computing platforms we have today are too slow and laggy for true virtual reality.

Ronald Hanson, who heads up the quantum teleportation research project at Delft, said that he will repeat the experiment again this summer at a distance of 1,300 meters, or eight-tenths of a mile.

“We do all this in a material that can be used to make chips out of,” he said in a statement. “This is important as many believe that only chip-based systems can be scaled up to a practical technology.”

    This is fantastic news! I think the current networking technologies are fast enough for virtual worlds to work very well, but this would certainly be times and times better.

    • Unfortunately, it’s years away… though the pace of technological development *is* accelerating, so we might see it sooner than we thought. My daughter’s majoring in quantum physics and I’m going to be in Boston tomorrow and hopefully will stop by and see her and will ask her what she thinks of all this. In particular, I’m curious as to whether the communication is at light speeds, or truly instantaneous.

        Good point. At speed of light a QE ‘signal’ would traverse 12,750Km of planet at 300000Km/s, so that is 42 milliseconds of latency. Though that appears good it is too high for immersive audio. Rosedale’s HiFi VW project demonstrated musicians can’t tolerate more than 20ms one-way latency: https://highfidelity.io/blog/2013/05/how-much-latency-can-live-musicians-tolerate/.

        To get the latency down to 10ms, the QE coms would have to be at 4x the speed of light.
