Near-Term Fermionic Simulation with Subspace Noise Tailored Quantum Error Mitigation
Miha PapiÄ, Manuel G. Algaba, Emiliano Godinez-Ramirez +4
Quantum error mitigation (QEM) has emerged as a powerful tool for the extraction of useful quantum information from quantum devices. Here, we introduce the Subspace Noise Tailoring…
Noise-Robust Estimation of Quantum Observables in Noisy Hardware
Amin Hosseinkhani, Fedor Å imkovic, Alessio Calzona +6
Error mitigation is essential for extracting reliable results from quantum computations performed on noisy intermediate-scale quantum hardware. Here we introduce Noise-Robust Estim…
Multi-Layer Cycle Benchmarking for high-accuracy error characterization
Alessio Calzona, Miha PapiÄ, Pedro Figueroa-Romero +1
Accurate noise characterization is essential for reliable quantum computation. Effective Pauli noise models have emerged as powerful tools, offering detailed description of the err…
Fermion-to-qubit encodings with arbitrary code distance
Manuel G. Algaba, Miha PapiÄ, Inés de Vega +2
We introduce a framework which allows to systematically and arbitrarily scale the code distance of local fermion-to-qubit encodings in one and two dimensions without growing the we…
Technology and Performance Benchmarks of IQM's 20-Qubit Quantum Computer
Leonid Abdurakhimov, Janos Adam, Hasnain Ahmad +111
Quantum computing has tremendous potential to overcome some of the fundamental limitations present in classical information processing. Yet, today's technological limitations in th…
