### Expected behavior
I'm calculating second-order derivatives of a parameterized circuit with shots. The rotation gates depend on a product of two different input variables, which causes the compu…

# Description
This project would build on efforts to catalog papers published using Qiskit or IBM Quantum systems (available [here](https://airtable.com/shrOkqk6NAUzYry8F)). In particular, this pro…

Currently, qsimcirq users who want to run on GPU must compile the code locally, as the wheels are built on Github Actions runners which [do not have the CUDA SDK](https://github.com/actions/virtual-en…

### Feature details
For good reason, the autograd features of pennylane don't work with circuits that conclude with `qml.sample()`. However, there are many circumstances wherein one would want to d…

### What is the expected enhancement?
I found that when I built custom data encoding methods in parameterized quantum circuit, we cannot use parameter instance(;qiskit.circuit.Parameter) at the qis…

### What is the expected enhancement?
Currently unit test in [TestQSVR](https://github.com/Qiskit/qiskit-machine-learning/blob/main/test/algorithms/regressors/test_qsvr.py) are based on the classific…

### Environment
- **Qiskit version**: qiskit==1.0.2
- **Python version**: 3.9.6
- **Operating system**: Mac
### What is happening?
I assign parameters to EfficientSU2 circuit the same way…

Add the code to take a circuit and a list of pauli operators and output the required circuits and then a fitter to calculate the expectation value of those pauli operators. A limiting case of full sta…

When a parameter is bound (`bqc = qc.bind_parameters({theta: 0.5})`) the parameter is not the value, therefore `bqc.data[0][0].params[0] != 0.5` (see the [change here](https://github.com/Qiskit/qiskit…
