Installation

The qulacs.simulator device can be installed with:

pip install pennylane-qulacs["cpu"]

Note that you need to include whether to install the CPU version (pennylane-qulacs["cpu"]) or the GPU version (pennylane-qulacs["gpu"]) of Qulacs for it to be installed correctly. Otherwise Qulacs will need to be installed independently:

pip install pennylane-qulacs

For more details on installation and dependencies, visit the PennyLane-Qulacs installation page.

Device Initialization

Initialize the device in PennyLane with:

import pennylane as qml
dev = qml.device('qulacs.simulator', wires=2)
