When data is encoded on single photons, detecting these very faint light signals to read out the quantum information becomes especially challenging. To achieve super-sensitive light detection at high speeds, we use revolutionary ‘self-differencing’ photon counters. Based on this capability, we can develop quantum enhanced imaging techniques to sense our environment.
Single Photon Detectors
Detector Technology
Single photon avalanche diodes (SPADs) are a versatile technology which can be used in a wide range of quantum information applications including QKD and quantum imaging. We can optimise the detector to the application by tuning properties such as the single photon detection efficiency and pixel number.
Quantum Enhanced Imaging
The newly developed quantum detectors offer extraordinary sensitivity combined with high timing resolution. By detecting weakly reflected laser pulses from distant objects, those features can be exploited to create quantum enhanced imaging systems that can outperform the 3D cameras or LiDAR systems available today. Such systems can ensure the safety of driver assisted and autonomous vehicles under challenging weather conditions.
