apply_to_all

apply_to_all(
    gate_operand: QCallable[QBit], 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[QBit]	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

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

[Qmod Classiq-library function]

Applies Hadamard transform to the target qubits.

Corresponds to the braket notation:

\[ H^{\otimes n} |x angle = rac{1}{\sqrt{2^n}} \sum_{y=0}^{2^n - 1} (-1)^{x \cdot y} |y angle \]

Parameters:

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

modular_increment

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

[Qmod Classiq-library function]

Adds \(a\) to \(x\) 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
