Overview of EPFL-AQUA Activities

Quantum imaging (single-photon generation and detection) ? Biosensors (PET, FLIM, FRET, NIRI, NIROT, superresolution microscopy) ? Automotive sensors (long distance, high speed telemetry for ADAS and autonomous driving) ? Time-to-digital converters in ASIC and FPGA ? Space sensors (guidance and docking in space)

Ultra-fast imaging (1Gfps camera) Quantum random number generators and QKD CryoCMOS for quantum computing applications (analog and

digital circuits at 4K and below
