Honeywell Quantum Solutions Devices

The PennyLane-Honeywell plugin provides the ability for PennyLane to access devices available via Honeywell Quantum Solutions’ cloud hardware service.

Cloud ion-trap machines

This PennyLane device connects you to ion-trap machines available from Honeywell Quantum Solutions. Once the plugin has been installed, you can use this device directly in PennyLane by specifying "honeywell.hqs" and providing the name of the online hardware machine you wish to access:

import pennylane as qml

dev = qml.device("honeywell.hqs", "machine_name", wires=2)

@qml.qnode(dev)
def circuit(w, x, y, z):
    qml.RX(w, wires=0)
    qml.CNOT(wires=[0,1])
    qml.RY(0.5, wires=0)
    return qml.expval(qml.PauliZ(0))

where machine_name is a string specifying the specific online hardware you wish to use. Contact Honeywell Quantum Solutions to receive platform access and machine names.

Remote backend access

The user will need to obtain access credentials for the Honeywell Quantum Solutions 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 Honeywell’s online platform.
