Qubricks for implementing unary data loaders.

UnaryQROM

UnaryQROM(**kwargs)

Bases: Qubrick

A unary-encoded data-loader.

This class provides a unary QROM (Quantum Read-Only Memory) data loader, which can be used to encode data into quantum registers.

Parameters:

Name	Type	Description	Default
**kwargs	dict[str, Any]	Additional keyword arguments passed to the Qubrick superclass.	{}

compute

compute(
    index_reg: Qubits,
    b_of_p: int,
    data: list,
    ctrl: int | Qubits = 0,
    *,
    clean: Qubits | None = None,
)

This method loads the given data into the quantum register using unary encoding.

Parameters:

Name	Type	Description	Default
index_reg	Qubits	The index register, encoded in unary.	required
b_of_p	int	The number of bits of precision per item to be loaded.	required
data	list	A list of integers representing the data to be loaded.	required
ctrl	int | Qubits	A control register for conditional loading. Defaults to 0.	0
clean	Qubits | None	Qubits encoding the output data. If left as None, the register is allocated on the fly.	None
