Here we provide 6 examples for 2 different machines, 2 tasks and 2 design spaces.

The table shows the expected results for these examples.

examples id	machine	task	design space	expected accuracy
2	IBMQ_Quito	MNIST-0123	U3+CU3	74%
3	IBMQ_Lima	MNIST-0123	U3+CU3	55.3%
4	IBMQ_Quito	FASHION-36	U3+CU3	90%
5	IBMQ_Lima	FASHION-36	U3+CU3	88.7%
6	IBMQ_Quito	FASHION-36	ZZ+RY	89%
7	IBMQ_Lima	FASHION-36	ZZ+RY	88.7%

For example, if you want to run example2, you only need to follow the instructions below.

However, if you want to run any other experiments, you can refer to our colab link for general experiments.

Installation

git clone https://github.com/Hanrui-Wang/pytorch-quantum.git
cd pytorch-quantum
pip install --editable .
pip install pathos
pip install tensorflow_model_optimization
export PYTHONPATH=.

Fix qiskit's bug

Now your qiskit version should be 0.32.1. Modify the part after line 346 of lib/python3.x/site-packages/qiskit/providers/aer/backends/aerbackend.py from this:

elif parameter_binds:
    # Handle parameter binding
    parameterizations = self._convert_binds(circuits, parameter_binds)
    assemble_binds = []
    assemble_binds.append({param: 1 for bind in parameter_binds for param in bind})
    qobj = assemble(circuits, self, parameter_binds=assemble_binds,
                    parameterizations=parameterizations)

to this:

elif parameter_binds:
            # Handle parameter binding
            # parameterizations = self._convert_binds(circuits, parameter_binds)
            # assemble_binds = []
            # assemble_binds.append({param: 1 for bind in parameter_binds for param in bind})

            qobj = assemble(circuits, self, parameter_binds=parameter_binds)

Store the token

Next entor the following code into the python interpreter to store a qiskit token to your local file. You can replace it with your own token from your IBMQ account.

from qiskit import IBMQ
IBMQ.save_account('0238b0afc0dc515fe7987b02706791d1719cb89b68befedc125eded0607e6e9e9f26d3eed482f66fdc45fdfceca3aab2edb9519d96b39e9c78040194b86e7858', overwrite=True)
