A short introduction to quantum sub-wavelength resolution. Talk given to the Low Dimensional Structures and Devices research group, University of Sheffield

Short presentation given at EPSRC Quantum Communications Hub meeting, Bristol, September 2019. After a quick summary of researches I have done in York and Sheffield, the slides present the protocol of “Boson-Sampling” private-key cryptography, aka the first application of Boson Sampling to quantum cryptography.
