Paradigm shifts with quantum holography and communication
Department of Physics
Location: Babbio Center, Room 219
Speaker: Juergen W Czarske, Director of Center Biomedical Computational Laser Systems (BIOLAS), and Institute for Circuits and Systems, based at TU Dresden
ABSTRACT
More than 40 Nobel Prizes have already been awarded for achievements in the field of optics, including the 2022 Nobel Prize for second-generation quantum technology. Novel methods with entangled photon pairs for imaging with undetected light are presented. This is a paradigm shift in the holographic imaging of biological tissue in the NIR/MIR range—without the use of a camera—and opens up promising prospects for non-invasive cancer diagnostics. Furthermore, the use of photon entanglement for quantum communication via the BBM92 protocol is addressed, thereby enabling secure key distribution. Fundamental insights are expected that will benefit both scientific progress and practical applications.
BIOGRAPHY
