### Problem Statement
In some cases we show a call to action to instrument your trace more (or in the new world, to use profiles to fill in the gaps)... but not here:
` to return a partial trace (potentially a mixed state) of the stabilizer `state`, and the `positions` are the qubits that …

## Theory
So the idea here is that when we do the partial trace with the situation when:
N_particles < N_subsys*(sps -1) (eq. 1)
The density matrix only has non-zero elements in the particle…

In #2268 an effort was made to reduce lego messages. However it appears trace notification emails still include lego messages.
Here sentence beginning and ending are glued together without allowing…

**Describe the bug**
In [partial trace](https://www.cvxpy.org/api_reference/cvxpy.atoms.affine.html#partial-trace), the docstring parameter states that we can use a tuple of ints. However, if we us…

## Description of bug / unexpected behavior
TracedPath mobjects disappear as soon as other objects are added to the scene.
## Expected behavior
I would have expected that they stay visible like o…

It would be nice to be able to compute the gradient of the log probability (in the new BayesFlow version).
For example, with the jax-backend, I would like to be able to do something along this line…

### Feature details
As the title suggests, this feature would extend `qml.math.partial_trace` functionality to handle PennyLane operators. The public facing function already exists. This issue is par…

### What happened?
the partial trace function of the tensor_1d module contains a bug that causes it to fail when the kept subsystem is the last site of the system. This can be fixed by adding the l…
