Amazon Braket Simulator Version 2




This Amazon Braket Simulator is a second generation of our Python open source library that provides an
implementation of a quantum simulators that you can run locally. 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 this Amazon Braket Simulator
You must have the Amazon Braket SDK installed to use the local simulator.
Follow the instructions in the README for setup.
Usage
Importing this package for the first time will install additional libraries and precompile the Julia modules, which may take a few additional minutes.
This will not be needed for subsequent runs.
The quantum simulator implementations StateVectorSimulatorV2 and DensityMatrixSimulatorV2 plug into the LocalSimulator interface in
Amazon Braket SDK, with the backend parameters as "braket_sv_v2" and "braket_dm_v2", respectively.
Executing a circuit using the simulator:
from braket.circuits import Circuit
from braket.devices import LocalSimulator

device = LocalSimulator("braket_sv_v2")

bell = Circuit().h(0).cnot(0, 1)
print(device.run(bell, shots=100).result().measurement_counts)

Documentation
Detailed documentation, 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-simulator-v2-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-simulator-v2-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 the test dependencies using the following command:
pip install -e ".[test]"

To run the unit tests:
tox -e unit-tests

You can also pass in various pytest arguments to run selected tests:
tox -e unit-tests -- your-arguments

For more information, please see pytest usage.
To run linters and doc generators and unit tests:
