 # Improving the accuracy of BQSKit compiled circuits with error mitigation
 
 In this tutorial we describe how to use error mitigation capabilities from [Mitiq](https://mitiq.readthedocs.io/en/stable/) together with the compilation capabilities of [BQSKit](https://bqskit.lbl.gov/) {cite}`Patel_2022_ACM`, a compiler for quantum circuits. BQSKit stands for Berkeley Quantum Synthesis Toolkit and it allows one "to compile quantum programs to efficient physical circuits for any QPU".

 In this tutorial, we employ ZNE, CDR, and VNCDR mitigation techniques to address errors in the simulation of the 1-D Transverse-Longitudinal Ising model using Mitiq. It is important to note that the results presented here are not original, but rather an attempt to reproduce some of the findings outlined in the paper available at {cite}`Sopena_2023_Quantum`.
