### How to convert tableau representation of random clifford gate into its matrix representation using stim?

Stim v1.8 doesn't have a method to do this, but you can get around that by using the state channel duality and the tableau simulator's state_vector method. Note that, once you get past 8 qubit ...

### Understanding Controlled Operation

The best way to see this is through an example. Consider the circuit below: qubit that is in an eigenstate of the unitary Note that $|-\rangle$ is an eigenstate ...

I'm late to the party, but here's my take: Pure qubit states As you said, the space of pure states of a single qubit can be described as a complex projective line $\mathbb{C}P^1$, which is ...
Definition of Choi–Jamiołkowski isomorphism states that $d$ is the dimension of the hilbert space while your generalized GHZ states is still with hilbert space dimension $2$ for each subsystem. The ...
