Emergent-Coupling-Based Ansatz Evaluated on a Superconducting Quantum Processor
Alina Joch, Kevin Lively, Benedikt Fauseweh
The performance of the variational quantum eigensolver depends critically on the choice of ansatz. In this work, we experimentally evaluate the emergent-coupling-based ansatz (ECBA…
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…
Sublinear Classical-to-Quantum Data Encoding using -Toffoli Gates
Vittorio Pagni, Gary Schmiedinghoff, Kevin Lively +2
Quantum state preparation, also known as encoding or embedding, is a crucial initial step in many quantum algorithms and often constrains theoretical quantum speedup in fields such…
A Quantum-Inspired Algorithm for Wave Simulation Using Tensor Networks
Kevin Lively, Vittorio Pagni, Gonzalo Camacho
We present an efficient classical algorithm based on the construction of a unitary quantum circuit for simulating the Isotropic Wave Equation (IWE) in one, two, or three dimensions…
