Development and experimental implementation of noise characterisation techniques on a superconducting quantum processor
Nelson M. M. Fernández, Francesco Grieco, Hetta Vappula +6
Noise characterisation not only enables error mitigation but also provides valuable information about the intrinsic performance of a quantum device, identifying dominant error cont…
Exploiting overcompleteness of Platonic-solid POVMs for shadow estimation
Dario Melegari, Stefano Mangini, Keijo Korhonen +2
Accurately estimating expectation values of observables from a finite number of measurement shots is a central challenge in quantum information science. Informationally overcomplet…
Characterization of Unlearnable Noise with Mid-Circuit-Measurement-Based Cycle Benchmarking
M. H. Cheng, Stefano Mangini, V. Bartsch +4
Noise characterization of multi-qubit entangling Clifford operations is a key practical bottleneck for quantum error mitigation and for the calibration, validation, and optimizatio…
Improving shadow estimation with locally-optimal dual frames
Keijo Korhonen, Stefano Mangini, Joonas Malmi +2
Accurate estimation of observables in quantum systems is a central challenge in quantum information science, yet practical implementations are fundamentally constrained by the limi…
TensorRL-QAS: Reinforcement learning with tensor networks for improved quantum architecture search
Akash Kundu, Stefano Mangini
Variational quantum algorithms hold the promise to address meaningful quantum problems already on noisy intermediate-scale quantum hardware. In spite of the promise, they face the…
Low variance estimations of many observables with tensor networks and informationally-complete measurements
Stefano Mangini, Daniel Cavalcanti
Accurately estimating the properties of quantum systems is a central challenge in quantum computing and quantum information. We propose a method to obtain unbiased estimators of mu…
Tensor network noise characterization for near-term quantum computers
Stefano Mangini, Marco Cattaneo, Daniel Cavalcanti +3
Characterization of noise in current near-term quantum devices is of paramount importance to fully use their computational power. However, direct quantum process tomography becomes…
