qrisp.QuantumArray.decoder

QuantumArray.decoder(code_int)

The decoder method specifies how a QuantumArray turns the outcomes of measurements into human-readable values. It recieves an integer i and returns an OutcomeArray.

Parameters:

iint

Integer representing the outcome of a measurement of the qubits of this QuantumArray.

Returns:

resnp.ndarray

An array with entries of the type of the results of the .decoder of the qtype of this array.

Examples

We create a QuantumFloat and inspect its decoder:

>>> from qrisp import QuantumArray, QuantumFloat
>>> qtype = QuantumFloat(3)
>>> q_array = QuantumArray(qtype, (2,2))
>>> print(q_array.decoder(1))
[[0 0]
 [0 1]]
