QCI Connect: A Modular Full-Stack Quantum Computing Platform
Eric Bertok, Hannes Busche, Florian Drinkler +17
In a world of various competing quantum computing architectures, hardware-agnostic, full-stack platforms are necessary to bring the full power of quantum computing hardware to doma…
Quantum Simulation of Magnetic Materials: from Ab-Initio to NISQ
Pascal Stadler, Florian G. Eich, Benedikt M. Schoenauer +5
Quantum computers are increasingly accessible, yet demonstrations of physically meaningful simulations for real materials remain scarce. In our work we simulate low-energy magnetic…
Reducing Quantum Error Mitigation Bias Using Verifiable Benchmark Circuits
Joseph Harris, Kevin Lively, Peter Schuhmacher
We present a simple, malleable and low-overhead approach for improving generic biased quantum error mitigation (QEM) methods, achieving up to 15% fidelity improvements over standar…
A mathematical justification to apply the secular approximation to the Redfield equation
Niklas J. Jung, Francesco Rosati, Gabriel L. Rath +2
Quantum master equations are widely used to describe the dynamics of open quantum systems. All these different master equations rely on specific approximations that may or may not…
Application-Aware Benchmarking on NISQ Hardware using Expectation Value Fidelities
Joseph Harris, Peter K. Schuhmacher
We present a low-cost protocol for benchmarking applications on generic quantum hardware in the circuit model. Using families of Clifford circuits which mimic the application circu…
Quantum Software Ecosystem Design
Achim Basermann, Michael Epping, Benedikt Fauseweh +7
The rapid advancements in quantum computing necessitate a scientific and rigorous approach to the construction of a corresponding software ecosystem, a topic underexplored and prim…
