Amazon Braket Default Simulator
An open-source Python library that simulates quantum circuits locally, so quantum programs written for the Amazon Braket SDK can be tested on a laptop before being submitted to the Braket cloud service.
The Amazon Braket Default Simulator is a local quantum circuit simulator distributed as a Python package. It implements a state-vector simulator and a density-matrix simulator, which plug into the Amazon Braket SDK's LocalSimulator interface as the braket_sv and braket_dm backends, letting a developer run and test quantum circuits on their own machine.
It requires the Amazon Braket SDK to be installed alongside it, and a circuit built with that SDK can be executed against the local simulator with a couple of lines of Python before being submitted to the hosted Amazon Braket service. The project ships unit tests and a tox-based workflow for generating its API reference documentation, and contributions are expected to pass the test suite.
