Dr. Karl Pelka

I am a quantum physicist interested in quantum optomechanics, quantum information, statistical optics, and non-linear dynamics with experience both in theory and experiment; a PADI Open Water Scuba Instructor; a passionate science communicator; a hobbyist programmer; and a happy husband and father.

For now, my postdoctoral journey brought me back to the University of Malta to work within the MQSENS project on the dynamics of bosonic modes forced into subspaces through repeated measurements, the so-called quantum Zeno dynamics, and on entanglement propagation in non-reciprocal bosonic arrays among other activities in the Department of Physics.

I read for my PhD at the University of Malta working on cooperative effects in nano- and optomechanics and studied for my BSc and MSc in Physics at the Friedrich-Alexander-Universität (Erlangen, Germany) specialising in quantum optics, quantum information and statistical optics both theoretically and experimentally.
