ENH: Improve performance of np.count_nonzero for float arrays

1

Improve performance of `np.count_nonzero` for float arays. The PR is similar to https://github.com/numpy/numpy/pull/18183, but uses a simple loop instead of SIMD instructions. * The template in `arraytypes.c.src` has more types...

### Informations - **Qiskit Aer version**: 0.15.0 - **Python version**: 3,12 - **Operating system**: Windows ### What is the current behavior? Using the `Result` from the Aer simulator results in...

**Describe the bug** The model pack `smq2Q_XY` includes the CPhase in the description and the gates, but it is not used in the germs or fiducials. https://github.com/sandialabs/pyGSTi/blob/d27e4e688a64914a0b7aaec1de91aa56f7ce70c2/pygsti/modelpacks/smq2Q_XY.py#L20-L23 Also the `smq2Q_XYI`...

**Describe the bug** To perform the GST measurements and analysis independently I tried to serialize the relevant structures after measurment, and then load the same structures later for analysis. This...

MAINT: Enable linting with ruff E501

2

Within the numpy codebase we aim to keep the maximum line length at 88 (https://github.com/numpy/numpy/pull/27320). We will enforce the ruff [E501 rule](https://docs.astral.sh/ruff/rules/line-too-long/) for the codebase step by step: List of...

BUG: Allow np.percentile to operate on float16 data

2

Fixes #29003 The approach taken to address the issue is to perform index calculations with increased precision, but keep the behaviour that for `arr` of dtype `float16` the output `np.quantile(arr,...

We improve performance of decoding by: * Reducing the number of times `fields(obj)` is calculated * Adding fast paths for the common types (e.g. int, float, str, ...) * Avoid...
