Qunicorn: A Middleware for the Unified Execution Across Heterogeneous Quantum Cloud Offerings
Benjamin Weder, Johanna Barzen, Martin Beisel +4
Quantum computers are available via a variety of different quantum cloud offerings. These offerings are heterogeneous and differ in features, such as pricing models or types of acc…
Joint Wire Cutting with Non-Maximally Entangled States
Marvin Bechtold, Johanna Barzen, Frank Leymann +2
Distributed quantum computing leverages the collective power of multiple quantum devices to perform computations exceeding the capabilities of individual quantum devices. A current…
Post-Quantum Security: Origin, Fundamentals, and Adoption
Johanna Barzen, Frank Leymann
Nowadays, predominant asymmetric cryptographic schemes are considered to be secure because discrete logarithms are believed to be hard to be computed. The algorithm of Shor can eff…
Quantum Software Engineering: Roadmap and Challenges Ahead
Juan M. Murillo, Jose Garcia-Alonso, Enrique Moguel +13
As quantum computers advance, the complexity of the software they can execute increases as well. To ensure this software is efficient, maintainable, reusable, and cost-effective -k…
Cutting a Wire with Non-Maximally Entangled States
Marvin Bechtold, Johanna Barzen, Frank Leymann +1
Distributed quantum computing supports combining the computational power of multiple quantum devices to overcome the limitations of individual devices. Circuit cutting techniques e…
Warm-Starting the VQE with Approximate Complex Amplitude Encoding
Felix Truger, Johanna Barzen, Frank Leymann +1
The Variational Quantum Eigensolver (VQE) is a Variational Quantum Algorithm (VQA) to determine the ground state of quantum-mechanical systems. As a VQA, it makes use of a classica…
