    Thermodynamics of precision in quantum non-equilibrium steady states
    11.07.2019
    Furthermore, by exploiting the geometry of the manifold of NESS states, we use parameter estimation in order to bound the co-variance of the currents in the NESS by the entropy production. Since our p

    Thought experiments on a quantum computer
    14.10.2021
    Users can customize the protocol of the experiment, the inner workings of agents (e.g. the quantum circuit that models their reasoning process), the abstract logical system used (which may or not allo

    Three "twisted" photons in three dimensions
    11.03.2016
    Researchers at the Institute of Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Universitat Autonoma de Barcelona have achieved a new milestone in quantum physics: th

    Time and Causality in Quantum Mechanics
    Illustration of an autonomous quantum clock running only on thermal resources. The heat current is used to drive a quantum system towards a dissipating state. The emitted photon is registered in a det

    Towards a measurement theory in QFT: "Impossible" quantum measurements are possible but not ideal
    07.03.2024
    We show that the same problem arises in non-relativistic quantum physics, where joint nonlocal measurements (i.e., between systems kept spatially separated) in general lead to signaling, while one wou

    Towards a test of the Quantum equivalence principle
    05.08.2021
    Specifically, in my thesis I considered an interferometric setup that employs atomic clocks to observe a superposition of gravitational time dilations. I showed that this system can test some features

    Towards a universal picture for quantum coherence
    03.09.2019
    Our studies include the representation of quantum effects via negative probabilities, so-called quasiprobability distributions, in theory and experiment. In addition, we elaborate on mappings of local

    Towards complete control of multi-level quantum systems
    07.11.2017
    Quantum information encoded in multi-level systems offer several advantages. As it allows encoding information beyond one bit per photon, both the data rate can be enhanced and the security of the com
