#2781 is related to this.

You're right, the issue is that `mat` is being mutated.

@iamvamsi Moments should be treated differently from operations. While you can attempt to insert operations into an existing moment, you should insert a moment all by itself. You should let...

From a brief discussion with @Strilanc : the proliferation of Circuit insertion methods indicates that instead of resolving this issue the way I stated it, we should instead somehow combine...

No, there was nothing in particular; it was more for the second reason you mention. It is not a high priority for me.

I actually don't know anything about this, but I asked Joe, who said that he would provide us with some.

@bryano Joe provided me with these notes: [multi.pdf](https://github.com/quantumlib/OpenFermion/files/2426186/multi.pdf)

We should wait until the extensions you mentioned are implemented.

Yes, it is. It does seem unnatural, but I wasn't sure how else to implement it using Cirq. I guess you could just continue repeating the circuit until you get...

It's an implementation of "iterative phase estimation" from https://arxiv.org/abs/quant-ph/0610214. The thing is that the complete algorithm consists of multiple stages, where each stage ends with a measurement. Furthermore, you want...
