devqubit-pennylane 0.1.12

devqubit adapter for Pennylane

devqubit-pennylane

PennyLane adapter for devqubit — automatic tape capture, device snapshots, and result logging for PennyLane devices and QNode workflows.

[!IMPORTANT] This is an internal adapter package. Install via pip install "devqubit[pennylane]" and use the devqubit public API.

Installation

pip install "devqubit[pennylane]"

Usage

import pennylane as qml
from devqubit import track

dev = qml.device("default.qubit", wires=2, shots=1000)

@qml.qnode(dev)
def circuit():
    qml.Hadamard(wires=0)
    qml.CNOT(wires=[0, 1])
    return qml.counts()

with track(project="pennylane-exp") as run:
    run.wrap(dev)       # in-place device patching
    counts = circuit()  # QNodes using this device are tracked automatically

Multi-Layer Stack

PennyLane can act as a frontend to other execution providers. The adapter captures the full stack:

# Braket backend through PennyLane
dev = qml.device("braket.aws.qubit", wires=2, device_arn="...")

# Qiskit backend through PennyLane
dev = qml.device("qiskit.remote", wires=2, backend="ibm_brisbane")
