Module containing Qubrick for the Majorana Fermion Operation.

MajoranaFermionOperator

MajoranaFermionOperator(
    operator, multiplexor_cls, **kwargs
)

Bases: Qubrick

The Majorana Fermion Operator shown in Fig. 9 of arXiv:1805.03662 .

Parameters:

Name	Type	Description	Default
operator	callable	A function implementing an operator taking in two arguments: (1) the qubit register (2) the control conditions. Typically either the x or y method of a QPU instance	required
multiplexor_cls	Qubrick	The class for a Qubrick that implements multiplexing	required
**kwargs	dict[str, Any]	Additional Qubrick kwargs	{}

compute

compute(
    index_reg: Qubits,
    target_reg: Qubits,
    ctrl: Qubits | int = 0,
)

Compute the Majorana Fermion Operation.

Parameters:

Name	Type	Description	Default
index_reg	Qubits	The qubit register that represents the indices to multiplex over	required
target_reg	Qubits	The qubit register that the Majorana Fermion Operator gets applied onto.	required
ctrl	Qubits or int	Additional classical or quantum control conditions. Defaults to 0 which performs the operation as if a control qubit were in the |1> state.	0
