This is the user-facing side where developers define the problem they want to solve (e.g., optimizing a supply chain or simulating a molecule).
At the lowest level, software must generate precise microwave pulses to manipulate qubits. This layer translates compiled instructions (e.g., "CNOT on qubits 1 and 2") into analog waveforms. Open-source frameworks like QUIL (Rigetti) and OpenPulse (IBM) standardize this interface. quantum ncomputing software
PennyLane is not a full-stack SDK but a differentiable programming library for quantum machine learning (QML). It integrates with PyTorch and TensorFlow, treating quantum circuits as just another neural network layer. If you want to train a quantum model via gradient descent, PennyLane is the tool. This is the user-facing side where developers define
