Anonymous Conference Key Agreement in Quantum Networks
Frederik Hahn, Jarn de Jong, Christopher Thalacker +3
Quantum Conference Key Agreement (CKA) is a cryptographic effort of multiple parties to establish a shared secret key. While bipartite quantum key distribution protocols are also u…
Correlations for computation and computation for correlations
Bülent Demirel, Weikai Weng, Christopher Thalacker +2
Quantum correlations are central to the foundations of quantum physics and form the basis of quantum technologies. Here, our goal is to connect quantum correlations and computation…
Linear multi-particle, multi-port interferometers and their matrix representations
Bülent Demirel
Interferences in multi-path systems for single and multiple particles are theoretically analyzed. A holistic method is presented, which allows to construct the unitary transition m…
Spin - Rotation Coupling Observed in Neutron Interferometry
Armin Danner, Bülent Demirel, Wenzel Kersten +4
Einstein's theory of general relativity and quantum theory form the two major pillars of modern physics. However, certain inertial properties of a particle's intrinsic spin are inc…
Experimental test of an entropic measurement uncertainty relation for arbitrary qubit observables
Bülent Demirel, Stephan Sponar, Alastair A. Abbott +2
A tight information-theoretic measurement uncertainty relation is experimentally tested with neutron spin-1/2 qubits. The noise associated to the measurement of an observable is de…
Residual error-disturbance uncertainties in successive spin-1/2 measurements tested in matter-wave optics
Bülent Demirel, Stephan Sponar, Georg Sulyok +2
The indeterminacy inherent in quantum measurement is an outstanding character of quantum theory, which manifests itself typically in Heisenberg's error-disturbance uncertainty rela…
Experimental test of entropic noise-disturbance uncertainty relations for spin-1/2 measurements
Georg Sulyok, Stephan Sponar, Buelent Demirel +4
Information-theoretic definitions for noise and disturbance in quantum measurements were given in Phys. Rev. Lett. 112, 050401 (2014) and a state-independent noise-disturbance unce…
