Unravelling motor protein organization on lysosomal membranes with super-resolution microscopy
This thesis first develops new methods for high-throughput and multi-color super-resolution microscopy (Chapters 2 and 3). Subsequently, I apply these methods to study the organization of motor proteins on the lysosome ...
Simulating quantum measurements and quantum correlations
This PhD thesis is focused on the quantum measurement simulability problem, that is, deciding whether a given measurement can be simulated when only a restricted subset of measurements is accessible. We provide an operational ...
Spontaneous parametric down-conversion sources for generation of atom-resonant quantum light
This thesis studies different designs of optical parametric oscillators as sources of atom-resonant quantum light resonant with the rubidium D1 line.We analyze the mode structure and filtering techniques in a conventional ...
