Quantum search algorithm for similar subgraph identification under fixed edge removal
Ruben Kara, Sven Danz, Tobias Stollenwerk +1
We introduce a novel quantum algorithm for similar subgraph identification in form of an NP-hard cardinality-constrained binary quadratic optimization problem. Given a weighted ref…
Bridging wire and gate cutting with ZX-calculus
Marco Schumann, Tobias Stollenwerk, Alessandro Ciani
Quantum circuit cutting refers to a series of techniques that allow one to partition a quantum computation on a large quantum computer into several quantum computations on smaller…
End-to-End Quantum Algorithm for Topology Optimization in Structural Mechanics
Leonhard Hölscher, Oliver Ahrend, Lukas Karch +5
Topology optimization is a key methodology in engineering design for finding efficient and robust structures. Due to the enormous size of the design space, evaluating all possible…
Towards Quantum Algorithms for the Optimization of Spanning Trees: The Power Distribution Grids Use Case
Carsten Hartmann, Nil Rodellas-Grà cia, Christian Wallisch +5
Optimizing the topology of networks is an important challenge across engineering disciplines. In energy systems, network reconfiguration can substantially reduce losses and costs a…
Better Embeddings with Coupled Adam
Felix Stollenwerk, Tobias Stollenwerk
Despite their remarkable capabilities, LLMs learn word representations that exhibit the undesirable yet poorly understood feature of anisotropy. In this paper, we argue that the se…
Quantum oracles for the finite element method
Sven Danz, Tobias Stollenwerk, Alessandro Ciani
In order to assess potential advantages of quantum algorithms that require quantum oracles as subroutines, the careful evaluation of the overall complexity of the oracles themselve…
