Error statistics and scalability of quantum error mitigation formulas
npj Quantum Information, 2023 Quantum computing promises advantages over classical computing in many problems. Nevertheless, noise in quantum devices prevents most quantum algorithms from achieving the quantum advantage.

Compressed quantum error mitigation
Physical Review B, 2023 We introduce a quantum error mitigation technique based on probabilistic error cancellation to eliminate errors which have accumulated during the application of a quantum circuit. Our approach is based on applying an optimal "denoiser" after the action of a noisy circuit and can be performed with an arbitrary number of extra gates.

Quantum Error Mitigation for Quantum State Tomography
IEEE Access, 2021 Quantum state tomography (QST) is the task of statistically constructing the density matrix of an unknown quantum state by measuring its several copies. The presence of noise in the QST setup can considerably degrade the fidelity between the constructed ...

SSQEM: Semi-Supervised Quantum Error Mitigation
2022 7th International Conference on Computer Science and Engineering (UBMK), 2022 One of the fundamental obstacles for quantum computation (especially in noisy intermediate-scale quantum (NISQ) era) to be a near-term reality is the manufacturing gate/measurement technologies that make the system state quite fragile due to decoherence.

Error mitigation with Clifford quantum-circuit data [PDF]
Quantum, 2021 Achieving near-term quantum advantage will require accurate estimation of quantum observables despite significant hardware noise. For this purpose, we propose a novel, scalable error-mitigation method that applies to gate-based quantum computers.

Zero-noise extrapolation for quantum-gate error mitigation with identity insertions [PDF]
, 2020 Quantum-gate errors are a significant challenge for achieving precision measurements on noisy intermediate-scale quantum (NISQ) computers. This paper focuses on zero-noise extrapolation (ZNE), a technique that can be implemented on existing hardware ...
