I would like to recommend the [QCompute:QEP](https://quantum-hub.baidu.com/qep/tutorial-mem) project, which implements a list of measurement error mitigation methods, including - the matrix inversion method ((by inverting confusion matrix), - the least...

I meet the same problem. The "Debug Output Logging" information from Zotero/Help/ is as follows: ``` TypeError: fileName is undefined getValidFileName@chrome://zotero/content/xpcom/file.js:1251:5 getNCFileName@chrome://mdnotes/content/mdnotes.js:414:14 getMDNoteFileName@chrome://mdnotes/content/mdnotes.js:421:10 getItemMetadata@chrome://mdnotes/content/mdnotes.js:238:30 getRegularItemContents@chrome://mdnotes/content/mdnotes.js:945:22 exportToMarkdownMenu@chrome://mdnotes/content/mdnotes.js:1037:26 ```

一个可选方案是将密度矩阵转换为Pauli Transfer Matrix表达，然后只需要可视化一个（更大的）实数矩阵。
