qrisp.QuantumArray.encoder

QuantumArray.encoder(encoding_array)

The encoder reverses the decoder, it turns arrays into integers based on the encoder of the qtype of this array.

Parameters:

encoding_array

An array where the entries can be read by the decoder of qtype.

Returns:

iint

The integer encoding the given array.

Raises:

Exception

Tried to call encoder on array with mismatching shape.

Examples

We create a QuantumArray and inspect it’s encoder:

>>> from qrisp import QuantumArray, QuantumFloat
>>> qtype = QuantumFloat(3)
>>> q_array = QuantumArray(qtype, (2,2))
>>> print(q_array.encoder(np.eye(2)))
