Orsolya Kálmán is a senior researcher at the Wigner Research Centre for Physics. She received her PhD at the University of Szeged in 2010. In her early career she theoretically studied interference phenomena and conductance properties of mesoscopic devices with an emphasis on their applicability for quantum informational tasks. Later, she investigated hybrid physical systems composed of ultracold atoms and mesoscopic conductors. In the past years she has been studying measurement-induced nonlinear quantum protocols and showed that they can be applied for relevant quantum informational problems, such as quantum state discrimination. Currently, she is working on the implementation of nonlinear quantum protocols in photonic platforms and gate-based quantum computers.
