Description:
PennyLaneHoneywell 0.34.1
❗ This plugin will not be supported in newer versions of PennyLane. It is compatible with versions
of PennyLane up to and including 0.34❗
The PennyLane-Honeywell plugin provides the ability to use Honeywell Quantum Solutions’ ion-trap
quantum computing hardware with PennyLane.
PennyLane provides open-source tools for
quantum machine learning, quantum computing, quantum chemistry, and hybrid quantum-classical computing.
Honeywell Quantum Solutions provides access to
ion-trap quantum computing hardware over the cloud.
Note
The PennyLane-Honeywell plugin is currently in beta release. Expect some features
to be updated or change in the future.
The plugin documentation can be found here: PennyLane-Honeywell.
Features
Provides a PennyLane device honeywell.hqs which can be used to access Honeywell Quantum Solutions’ online hardware API.
Supports core PennyLane operations such as qubit rotations, Hadamard, basis state preparations, etc.
Installation
PennyLane-Honeywell only requires PennyLane for use, no additional external frameworks are needed.
The plugin can be installed via pip:
$ python3 -m pip install pennylane-honeywell
Alternatively, you can install PennyLane-Honeywell from the source code by navigating to the top directory and running
$ python3 setup.py install
If you currently do not have Python 3 installed,
we recommend Anaconda for Python 3, a distributed
version of Python packaged for scientific computation.
Software tests
To ensure that PennyLane-Honeywell is working correctly after installation, the test suite can be
run by navigating to the source code folder and running
$ make test
Documentation
To build the HTML documentation, go to the top-level directory and run
$ make docs
The documentation can then be found in the doc/_build/html/ directory.
Getting started
Once PennyLane-Honeywell is installed, available Honeywell devices can be accessed straight
away in PennyLane. However, the user will need access credentials for the Honeywell Quantum Solutions (HQS) platform in
order to use these remote devices. These credentials should be provided to PennyLane via a
configuration file or environment variable.
Specifically, the variable HQS_TOKEN must contain a valid access key for HQS’s online platform.
You can instantiate the HQS device class for PennyLane as follows:
import pennylane as qml
dev1 = qml.device("honeywell.hqs", "machine_name", wires=2)
where machine_name is the specific name of the online device you’d like to access. Contact Honeywell Quantum
Solutions to receive platform access and machine names.
HQS devices can then be used just like other devices for the definition and evaluation of
quantum circuits within PennyLane. For more details and ideas, see the
PennyLane website and refer
to the PennyLane documentation.
