`modular_increment`	[Qmod Classiq-library function].

apply_to_all(
gate_operand: QCallable[Annotated[QBit, target]],
target: QArray[QBit]
) -> None

[Qmod Classiq-library function] Applies the single-qubit operand gate_operand to each qubit in the qubit array target. Parameters:

Name	Type	Description	Default
`gate_operand`	`QCallable[Annotated[QBit, target]]`	The single-qubit gate to apply to each qubit in the array.	required
`target`	`QArray[QBit]`	The qubit array to apply the gate to.	required

hadamard_transform(
target: QArray[QBit]
) -> None

[Qmod Classiq-library function] Applies Hadamard transform to the target qubits. Corresponds to the braket notation:

H^{\otimes n} |x\rangle = \frac{1}{\sqrt{2^n}} \sum_{y=0}^{2^n - 1} (-1)^{x \\cdot y} |y\rangle

Parameters:

Name	Type	Description	Default
`target`	`QArray[QBit]`	qubits to apply to Hadamard transform to.	required

modular_increment(
a: CInt,
x: QNum
) -> None

[Qmod Classiq-library function] Adds

a

x

modulo the range of

x

, assumed that

x

is a non-negative integer and

a

is an integer. Mathematically it is described as:

x = (x+a)\ \mod \ 2^{x.size}-1

Parameters:

Name	Type	Description	Default
`a`	`CInt`	A classical integer to be added to x.	required
`x`	`QNum`	A quantum number that is assumed to be non-negative integer.	required
