Description:
amazonbraketqrackcudasimulator 0.3.1
Amazon Braket (SDK) Qrack Simulator
This is an Amazon Braket SDK back end for the open-source unitaryfund/qrack simulator. (PyQrack provides pure Python language bindings from C++ Qrack.) This simulator can be run locally, via either a (vendor-agnostic) OpenCL implementation or a (NVIDIA-specific) CUDA implementation. (CPU-only local simulation is also supported, when compiling and installing Qrack from source.) You can use the simulator to test quantum tasks that you construct for the Amazon Braket SDK before you submit them to the Amazon Braket service for execution.
Setting up Amazon Braket Qrack Simulator Python
Installing this package will install the Amazon Braket SDK, necessary to use the local simulator.
For manual installation of the SDK, follow the instructions in the README for setup.
Checking the version of the Qrack simulator
You can check your currently installed version of amazon-braket-qrack-simulator with pip show:
pip show amazon-braket-qrack-simulator
or alternatively from within Python:
>>> from braket import qrack_simulator
>>> qrack_simulator.__version__
Usage
The quantum simulator implementation BraketQrackSimulator plugs into the LocalSimulator interface in
Amazon Braket SDK, with the backend parameter as "qrack".
Executing a circuit using the default simulator
from braket.circuits import Circuit
from braket.devices import LocalSimulator
device = LocalSimulator(backend="qrack")
bell = Circuit().h(0).cnot(0, 1)
print(device.run(bell, shots=100).result().measurement_counts)
Documentation
BraketQrackSimulator follows a subset of the Amazon Braket SDK default simulator input and output interfaces. Detailed documentation for the default simulator, including the API reference, can be found on Read the Docs.
To generate the API Reference HTML in your local environment
First, install tox:
pip install tox
To generate the HTML, first change directories (cd) to position the cursor in the amazon-braket-qrack-simulator-python directory. Then, run the following command to generate the HTML documentation files:
tox -e docs
To view the generated documentation, open the following file in a browser:
../amazon-braket-qrack-simulator-python/build/documentation/html/index.html
Testing
If you want to contribute to the project, be sure to run unit tests and get a successful result
before you submit a pull request. To run the unit tests, first install pytest, if necessary:
pip install pytest
With pytest installed, use this command in the amazon-braket-qrack-simulator-python directory:
