Berkeley Quantum Synthesis Toolkit
Berkeley Quantum Synthesis Toolkit (BQSKit)
The Berkeley Quantum Synthesis Toolkit (BQSKit) [bis • kit] is a powerful and portable quantum compiler framework. It can be used with ease to compile quantum programs to efficient physical circuits for any QPU.
BQSKit is available for Python 3.8+ on Linux, macOS, and Windows. BQSKit and its dependencies are listed on the Python Package Index, and as such, pip can easily install it:
pip install bqskit
An optional extension includes pre-built support for many quantum devices and modules for working with other quantum frameworks. Pip can install this extension by appending
[ext] to the previous command:
pip install 'bqskit[ext]'
Note: If you are using a device with Apple Silicon, you will need to install BQSKit with Anaconda. See the instructions here for more information. We are currently in the process of implementing native ARM support. When that is ready, we will update this note.
A standard workflow utilizing BQSKit consists of loading a program into the framework, modeling the target QPU, compiling the program, and exporting the resulting circuit. The below example uses BQSKit to optimize an input circuit provided by a qasm file:
from bqskit import compile, Circuit # Load a circuit from QASM circuit = Circuit.from_file("input.qasm") # Compile the circuit compiled_circuit = compile(circuit) # Save output as QASM compiled_circuit.save("output.qasm")
