openfermion.transforms.checksum_code
Checksum code for either even or odd Hamming weight.
openfermion.transforms.checksum_code(
n_modes: int, odd: Union[int, bool]
) -> openfermion.ops.BinaryCode
The Hamming weight
is defined such that it yields the total occupation number for a given basis
state. A Checksum code with odd weight will encode all states with odd
occupation number. This code saves one qubit: n_qubits = n_modes - 1.
Args |
n_modes
|
int
number of modes
|
odd
|
int or bool
1 (True) or 0 (False), if odd,
we encode all states with odd Hamming weight
|
Returns (BinaryCode): The checksum BinaryCode
