It's fairly simple to compute von Neumann entropy of a stabilizer state given its tableau and a partitioning of the qubit register, see e.g. [here](https://quantumcomputing.stackexchange.com/a/37983/1…

I am trying to run the following circuit with and without partitioning:
```js
import QuantumCircuit from 'quantum-circuit';
import fs from 'fs';
function getGates(circuit) {
var gates = …

Various errors occur when a training is running and the main data (e.g. number of qubits) is changed during that.
Please disable inputs during training and add stop training button.

**Describe the bug**
When the openqasm IR includes `#pragma braket result expectation z($0) @ z($1)`, `Circuit.from_ir` throws error `line 1:28 no viable alternative at input 'z($0'`.
This error o…

I ran across a problem that I thought was a non-terminating program, but turns out to be severe performance degradation when using vmap on large amounts of data, such as a QNode returning `qml.probs()…

**Description of the issue**
I encountered an issue when attempting to decompose the unitary matrix of QFT(4) using the built-in `quantum_shannon_decomposition` function in Cirq.
According to th…
