Hello, I would like to try default.qubit.torch
on a gpu device in my code using
self.dev = qml.device('default.qubit.torch', wires=wires, torch_device=self.device)
I however got the error message
File "/CT/QDM/work/conda/miniforge3/envs/QDM/lib/python3.13/site-packages/pennylane/devices/device_constructor.py", line 287, in device
raise qml.DeviceError(
f"Device {name} does not exist. Make sure the required plugin is installed."
)
The output of qml.about()
indeed shows that such a device is not present
Python version: 3.13.5
Numpy version: 2.2.6
Scipy version: 1.15.3
Installed devices:
- lightning.gpu (PennyLane_Lightning_GPU-0.41.1)
- lightning.qubit (PennyLane_Lightning-0.41.1)
- default.clifford (PennyLane-0.41.1)
- default.gaussian (PennyLane-0.41.1)
- default.mixed (PennyLane-0.41.1)
- default.qubit (PennyLane-0.41.1)
- default.qutrit (PennyLane-0.41.1)
- default.qutrit.mixed (PennyLane-0.41.1)
- default.tensor (PennyLane-0.41.1)
- null.qubit (PennyLane-0.41.1)
- reference.qubit (PennyLane-0.41.1)
Could you help me on how to install that?
