Volumetric Benchmarking of Error Mitigation with Qermit [PDF]

Quantum, 2023
The detrimental effect of noise accumulates as quantum computers grow in size. In the case where devices are too small or noisy to perform error correction, error mitigation may be used.

Numerical Aspects of Multilateration for Volumetric Error Calculation

Machines, 2022
We discuss two approaches to multilateration with a particular focus on numerical aspects for a given dataset. More precisely, we calculate the volumetric errors of the MCV 754 milling machine from the data measured by a LaserTRACER and provide criteria ...
