Mitigating depolarizing noise on quantum computers with noise-estimation circuits

M Urbanek, B Nachman, VR Pascuzzi, A He… - Physical review …, 2021 - APS
A significant problem for current quantum computers is noise. While there are many distinct
noise channels, the depolarizing noise model often appropriately describes average noise …

Benchmarking near-term quantum computers via random circuit sampling

Y Liu, M Otten, R Bassirianjahromi, L Jiang… - arxiv preprint arxiv …, 2021 - arxiv.org
The increasing scale of near-term quantum hardware motivates the need for efficient noise
characterization methods, since qubit and gate level techniques cannot capture crosstalk …

[HTML][HTML] Qubit noise deconvolution

S Mangini, L Maccone, C Macchiavello - EPJ Quantum Technology, 2022 - Springer
We present a noise deconvolution technique to remove a wide class of noises when
performing arbitrary measurements on qubit systems. In particular, we derive the inverse …

Hardware-efficient random circuits to classify noise in a multiqubit system

JS Kim, LS Bishop, AD Córcoles, S Merkel, JA Smolin… - Physical Review A, 2021 - APS
In this work, we extend a multiqubit benchmarking technique known as the binned output
generation (BOG) in order to discriminate between coherent and incoherent noise sources …
