Installation

pip install qandle

Usage

import torch
import qandle

# Create a quantum circuit
circuit = qandle.Circuit(
    layers=[
        # embedding layer
        qandle.AngleEmbedding(num_qubits=2),
        # trainable layer, with random initialization
        qandle.RX(qubit=1),
        # trainable layer, with fixed initialization
        qandle.RY(qubit=0, theta=torch.tensor(0.2)),
        # data reuploading
        qandle.RX(qubit=0, name="data_reuploading"),
        # disable quantum weight remapping
        qandle.RY(qubit=1, remapping=None),
        qandle.CNOT(control=0, target=1),
        qandle.MeasureProbability(),
    ]
)


input_state = torch.rand(circuit.num_qubits, dtype=torch.float) # random input
data_reuploading = torch.rand(1, dtype=torch.float) # random data reuploading input

# Run the circuit
circuit(input_state, data_reuploading=data_reuploading)
