A new paper on our state-of-the-art 14-pixel single photon detector with photon number resolution is now out in Nano Letters! Our novel design uses 14 independent pixels in an interleaved geometry, allowing the device to deliver high performance single-photon detection, whilst also being able to resolve the number of photons incident on the detector. These types of devices could find immediate application in linear optic quantum computing.

Patrik Caspar has received his PhD for work related to Heralded Single Photon Sources. Thesis Title: Photonic Entanglement Certification and Distribution Based on Single Photons

Two recent articles from our group demonstrate a novel photon-number-resolving (PNR) detector, based on a high-efficiency parallel SNSPD (P-SNSPD), and its application in quantum optics experiments! The results are out now in Physical Review Applied and Quantum Science and Technology. The novel architecture P-SNSPD design prevents electrical and thermal crosstalk. The development of the P-SNSPD allowed a significant improvement to be made to one of our existing heralded single photon sources.
