​

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:

​

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:

​

inplace_encode_on_bloch

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

[Qmod Classiq-library function] Creates a dense angle encoding of n data points on n//2 qubits. Encodes pairs of data points, normalized in the range [-1, 1], on a Bloch sphere, via RX(pidata[2i])RZ(pidata[2i+1]) on qba[i], such that the i’th qubit transforms as \|0> -> cos(pidata[2i]/2)\|0> +i*$e^\{i * pi * data[2*i+1]\}$sin(pidata[2*i+1]/2). If the length of the data is odd then RX(data[i]) is applied on the last qubit. Parameters:
