What is it? 

The ID281 SNSPD (Superconducting Nanowire Single-Photon Detector) System is an advanced single-photon detection system designed for high-performance quantum sensing applications. 

It utilises superconducting nanowire technology to detect individual photons according to different test requirements, with outstanding efficiency and precision.

 

What does it do?  

The system detects single photons, the smallest units of light, with high efficiency, low timing jitter, and minimal dark counts.  

 This ability makes it ideal for applications requiring ultra-sensitive photon detection, such as quantum communications, quantum computing, sensing and advanced optical measurements.  

 These applications sometimes have some of the smallest and weakest photons due to low temperature cryogenic condition and complex materials that need ultra sensitivity to detect singular photons and understand how each photon behaves in a device.  

Who is it for?  

The system will allow customers developing quantum technology to conduct precise measurements and experiments.  

 The system will help us accelerate product development for in-demand devices that will optimise quantum applications. 

 This equipment addresses industry challenges by providing the necessary tools to explore and refine quantum technologies, which are crucial for delivering next generation secure communications, advanced computing and sensing, and quantum networks. 

 

How is this single-photon system unique?  

This single photon system is not widely available. At the Future Telecoms Hub, we aim to provide a place for customers to test, evaluate and optimise their quantum technologies – these capabilities are rare to find in one place in the UK.  

This equipment enables us to test and evaluate hardware that the companies we work with develop. Using the expertise and skills we have at the Catapult, we can advise on how best to optimise these systems to make better products and build sovereign capabilities in the UK. 

The ID281 SNSPD system is a significant milestone for the Future Telecoms Hub and CSA Catapult. It enhances CSA Catapult's research and development capabilities in quantum technologies. 

We can undertake more complex and sensitive experiments and further contribute to quantum hardware innovation in the UK.  

The system also provides a platform for collaboration with academia and industry partners, expanding CSA Catapult's impact in this field. 

Part of our role is to help industry and academia develop hardware for applications that overcome industry challenges and reduce costs to meet growing demand, from boosting computing speed to sending encrypted, secure data, high-sensitivity testing and artificial intelligence processing and connectivity for future telecoms. 

We look forward to the ground breaking research and innovations that this system will enable.
