QIntOnesComp#

qualtran.QIntOnesComp

Signed Integer of a given width bitsize.

qualtran.QIntOnesComp(
    bitsize
)

In contrast to QInt, this data type uses the ones’ complement representation for negative integers.

Here (and throughout Qualtran), we use a big-endian bit convention. The most significant bit is at index 0.

Attributes

bitsize: The number of qubits used to represent the integer.
num_bits
num_cbits: Number of classical bits required to represent a single instance of this data type.
num_qubits: Number of qubits required to represent a single instance of this data type.

is_symbolic() -> bool

Returns True if this dtype is parameterized with symbolic objects.

to_bits(
    x: int
) -> List[int]

Yields individual bits corresponding to binary representation of x

from_bits(
    bits: Sequence[int]
) -> int

Combine individual bits to form x

get_classical_domain() -> Iterable[int]

Yields all possible classical (computational basis state) values representable by this type.

assert_valid_classical_val(
    val, debug_str: str = 'val'
)

Raises an exception if val is not a valid classical value for this type.

Args

__ne__(
    other
)

Check equality and either forward a NotImplemented or return the result negated.

__eq__(
    other
)

Method generated by attrs for class QIntOnesComp.
