Are you interested in adding support for the complex PSD cone? It shows up all the time in quantum information problems, and is much more efficient than mapping the problem to the real PSD cone via

Suppose I have a quantum `CSS` code: `(H = Hx|Hz) `where `H` is a `Boolean/GF(2) `matrix. Eric noted that I can do `S = StabilizerCode(H);` then `minimum_distance(S)` to find the minimum distance. I …

After a thorough examination of the repository, I've come to a startling conclusion: the code appears to be... missing. Now, I understand this might sound like a trivial matter, but hear me out. This…

### What happened?
There is no subspace information in a control problem.
Consider a three level transmon
```Julia
η = -0.2
a = annihilate(3)
sys = QuantumSystem(η / 2 * a'*a'*a*a, [(a + a')…

### Expected behavior
When the script is executed, the SX operation should be applied to the qubit at index 1, as specified in the circuit definition. The QASM string generated from the circuit shoul…

At some point this year I had to cite the ISQCMC Berlin proceedings as a whole, for a book chapter. This is what I ended up using in my case, in APA Format:
Hamido, O. C. and Itaboraı́, P. V. (eds.) …

### Expected behavior
I want to call `qml.adjoint(qml.DepolarizingChannel)(0.1, wires=0)` with the `default.mixed` device. I expect the circuit to perform the adjoint of qml.DepolarizingChannel
