Shanghai team builds single-photon detector with over 100 channels
In short
- Detectors could previously support a maximum of 32 detection channels for photon signals.
- A Shanghai-based team developed a new interconnect scheme that supports more than 100 channels.
- The team reports the channels maintain accurate detection, which the broader quantum internet would need.

Single-photon detectors are core parts of photonic quantum technology. The limit of 32 channels has held back how much signal such systems can handle. The new interconnect scheme lifts that limit while keeping detection accurate, though the source describes it as a route to broadband quantum networks rather than a finished network.
From South China Morning Post
Chinese scientists have developed a 100-channel single-photon detector, a breakthrough promising to pave the way for broadband quantum networks. State-of-the-art single-photon detectors – essential components underpinning photonic quantum technologies – could previously support a maximum of 32 detection channels for photon signals. Now, a newly developed interconnect scheme by a Shanghai-based team has broken this bottleneck, supporting more than 100 detection channels while maintaining accurate...

Tiny particles of light are called photons. Scientists in Shanghai built a special machine that can count many of these tiny lights at once. This may help build faster quantum internet networks one day. What do you think you would send over a super-fast network?
