encode_in_angle

encode_in_angle(
    data: CArray[CReal], qba: Output[QArray[QBit]]
) -> None

[Qmod Classiq-library function]

Creates an angle encoding of n data points on n qubits.

Applies RY(\(\pi\)data[i]) on qba[i].

Parameters:

Name	Type	Description	Default
data	CArray[CReal]	A classical array representing the data to encode.	required
qba	Output[QArray[QBit]]	The array of qubits on which the data is encoded.	required

encode_on_bloch

encode_on_bloch(
    data: CArray[CReal], qba: Output[QArray]
) -> None

[Qmod Classiq-library function]

Creates a dense angle encoding of n data points on n//2 qubits.

Encodes pairs of data points on a Bloch sphere, via RX(\(\pi\)data[2i])RZ(\(\pi\)data[2i+1]) on qba[i]. If the length of the data is odd then RX(\(\pi\)data[i]) is applied on the last qubit.

Parameters:

Name	Type	Description	Default
data	CArray[CReal]	A classical array representing the data to encode.	required
qba	Output[QArray]	The QArray of QBits on which the data is encoded.	required
