    Hidden bridge between Quantum Experiments and Graph Theory uncovered using Melvin
    18.12.2017
    for the calculation of technical solutions for quantum physical experiments [1]. For a general question asked last year, Melvin provided a solution that proved to be surprisingly practical - but initially completely out of touch with human intuition [2]. Remarkable number sequence "The solution could practically be implemented in the form of an experiment in the laboratory," confirms quantum physicist Mario Krenn from the research group of Anton Zeilinger, professor at the ...

    Quantum Geometry of the Light Cone
    09.04.2024
    that the shear of the null boundary follows the profile of a step function. The angular dependence is arbitrary. Next, I explain how to solve the residual constraints, which are the Raychaudhuri equation and a Carrollian transport equation for an SL(2,R) holonomy. The resulting submanifold in phase space is symplectic. Along each null generator, we end up with a simple mechanical system. The quantization of this system is straightforward. The physical Hilbert space is the ...

    We will discuss recent proposals along this line and give more details for two harmonic oscillators coupled gravitationally. Finally, some thoughts on the limits of this approach will be presented. Monday, July 16, 2018 11:00 am IQOQI Seminar room, 2nd floor Boltzmanngasse 3, 1090 Vienna Hosted by: Časlav Brukner

    Composable security in relativistic quantum cryptography
    02.11.2021
    Minkowski space (or superpositions thereof). This allows us to analyse relativistic protocols and to derive novel possibility and impossibility results. We show that (1) coin flipping can be constructed from the cryptographic primitive, channel with delay, (2) composably secure bit commitment, biased coin flipping and channel with delay are all impossible without set-up assumptions, and (3) it is impossible to securely increase the delay time of a channel with delay.

    Invitation to a talk by Pavel Kroupa on Wednesday, December 6th 2017, 16:00h

    Milgromian dynamics predicts a new physical phenomenon, the external field effect, and it is shown that astronomical data indeed bear evidence for this phenomenon, which is strictly non-Newtonian.
