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 and stable operation.
“This work establishes a robust and scalable infrastructure, paving the way for large-scale quantum photonic applications,” the authors said in their paper.
