Quantum Circuit Cutting Experiment

This project demonstrates the use of circuit cutting techniques in quantum computing using Qiskit. It allows running experiments on both local simulators and IBM Quantum hardware.

Dependencies

To run this project, you need to install the following Python packages:

numpy
qiskit
qiskit-ibm-runtime
qiskit-aer
circuit_knitting

You can install these dependencies using pip:

pip install numpy qiskit qiskit-ibm-runtime qiskit-aer circuit_knitting

Configuration

Before running the experiment on IBM Quantum hardware, make sure to replace the token in the QiskitRuntimeService initialization with your own IBM Quantum account token:

service = QiskitRuntimeService(channel="ibm_quantum", token="your_token_here")

Usage

The main function in the script is experiment_with_circuit(num_qubits, depth, use_ibmq=False).

To run a local simulation:

results, total_time, original_time = experiment_with_circuit(8, 4, use_ibmq=False)

To run on IBM Quantum hardware:

results, total_time, original_time = experiment_with_circuit(8, 3, use_ibmq=True)

Output

The script will print information about the circuit cutting process, execution times, and save the results in a results.json file.

Note

Running on IBM Quantum hardware requires an IBM Quantum account and may incur usage costs. Make sure you understand the implications before running experiments on real quantum hardware.
