Asymmetric quantum error correction efficiently tackles application-specific noise effects
Abhishek Yadav, Peter K. Schuhmacher, Michael Epping
Noise is a major challenge for current quantum computers. It can be broadly categorized into bit-flip and phase-flip errors. These two types do not necessarily affect the executed…
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
