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…

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…
