Yishai Klein, PhD
Yishai Klein earned his Ph.D. in Physics from Bar Ilan University in 2023, specializing in X-ray imaging and spectroscopy with a focus on single-pixel detection. Under the supervision of Prof. Sharon Shwartz, he developed new detection methods using structured illumination techniques, improving X-ray imaging and spectroscopy in various sources, including laboratory sources, synchrotrons, and x-ray-free electron lasers. Notably, he demonstrated the first use of quantum interferometry with an X-ray SU (1,1) interferometer. He joined the SQO group in Ottawa as a postdoctoral researcher, moving to the optical range but still focusing on new SU (1,1) approaches and including quantum imaging and super-resolution projects.
