  • Mapping quantum circuits to shallow-depth measurement patterns based on graph states

    Speaker: Dr. Matthias Heller, Fraunhofer Institute for Computer Graphics Research IGD Title: Mapping quantum circuits to shallow-depth measurement patterns based on graph states Abstract: The paradigm of measurement-based quantum computing (MBQC) starts from a highly entangled resource state on which unitary operations are executed through adaptive measurements and corrections ensuring determinism. This is set in […]

  • Comm. & Sec. Track meeting: Fault-tolerant coding for quantum communication

    Zoom

    Speaker: Alexander Mueller-Hermes Title: Fault-tolerant coding for quantum communication Location: Zoom (link in Google Group) Abstract:  Designing encoding and decoding circuits to reliably send messages over many uses of a noisy channel is a central problem in communication theory. When studying the optimal transmission rates achievable with asymptotically vanishing error it is usually assumed that […]

  • Expressive and Constraint-Preserving QAOA for the Minimum Vertex Cover with Optimized Initializations

    Speaker: Finley Quinton, NTNU Title: Expressive and Constraint-Preserving QAOA for the Minimum Vertex Cover with Optimized Initializations Abstract: Our work investigates advanced Quantum Approximate Optimization Algorithm (QAOA) strategies for the Minimum Vertex Cover (MVC) problem on weighted graphs, emphasizing constraint-preserving mixers and their performance against traditional penalty-based approaches. We analyze both the standard constraint-preserving mixer […]

  • Communication and Security Track November Meeting

    Speaker: Hans Heum Title: Cryptographic Group Actions in a Quantum World Abstract: The Group Action formalism generalizes the familiar discrete-logarithm based hardness assumptions in such a way that post-quantum security can be recovered. In particular, post-quantum group actions have been shown to be instantiable from isogeny-based cryptography, such as CSIDH and more recently PEGASIS. Thus, many useful results from the […]

    Novel methods for quantum information processing

    In this talk I present a way to transfer methods from signal processing, like the short-time Fourier transform or the wavelet transform and the respective reconstruction formulae, to the quantum setting. This approach works for discrete variables and continuous variables quantum systems. The focus is going to be on the operator short-time Fourier transform and the polarized Cohen’s class of an operator. This is joint work with Monika Doerfler, Henry McNulty and Eirik Skrettingland.
