[Extreme Tech] Chinese physicists create first single-photon quantum memory, leading to quantum internet

A lab in China is reporting that it has constructed the first memory device that uses single photons to store quantum data. This is a significant breakthrough that takes us further down the path towards a quantum internet, and potentially quantum computing as well.

As it currently stands, we already make extensive use of photons — the bulk of the internet and telecommunications backbone consists of photons traveling down fiber optic cables. Rather than single photons, though, these signals consist of carrier light waves of millions of photons, with the wave being modulated by binary data. These pulses are never stored, either; when they reach a router, they’re converted into electrical signals, and then stored in RAM before being converted back into light.

Is it me, or does it seem like all of the cool quantum research is going on in china?

You're not alone.

Of course, the technologies that end up making the quantum internet of the future will depend on many other factors, not least of which will be a significant dollop of luck. But given the numerous advances in this area made by Chinese labs in recent years, only a fool would bet against Chinese technology playing a significant role in the way we quantum communicate in future.

But who cares who does it, right? We're now one more step closer to quantum internet.
