Custom Quantum Encoding
------------------------

Implementing custom quantum encoding methods:

.. code-block:: python

   import quscope
   import numpy as np
   from qiskit import QuantumCircuit
   
   # Create custom encoder class
   class CustomEncoder(quscope.QuantumImageEncoder):
       def custom_encode(self, image_data):
           """Custom encoding method."""
           circuit = QuantumCircuit(self.num_qubits)
           # Add custom encoding logic here
           return circuit
   
   # Use custom encoder
   image_data = np.random.rand(4, 4)
   encoder = CustomEncoder(image_size=(4, 4))
   circuit = encoder.custom_encode(image_data)

EELS Analysis Workflow
----------------------

Complete electron energy loss spectroscopy analysis:

.. code-block:: python

   import quscope.eels_analysis as eels
   import numpy as np
   
   # Simulate EELS data
   eels_data = np.random.rand(100, 100, 512)
   
   # Preprocess EELS data
   processed_data = eels.preprocess_eels_data(eels_data)
   
   # Apply quantum processing
   result = eels.quantum_process_eels(processed_data)

Performance Optimization
------------------------

Optimizing quantum circuits for better performance:

.. code-block:: python

   import quscope
   from qiskit.transpiler import PassManager
   from qiskit.transpiler.passes import Optimize1qGates
   
   # Create and optimize circuit
   image_data = np.random.rand(4, 4)
   encoder = quscope.QuantumImageEncoder(image_size=(4, 4))
   circuit = encoder.encode_amplitude_encoding(image_data)
   
   # Optimize the circuit
   pass_manager = PassManager([Optimize1qGates()])
   optimized_circuit = pass_manager.run(circuit)
