qrisp.QuantumFloat.significant#

QuantumFloat.significant(k)[source]#

Returns the qubit with significance $k$.

Parameters:

kint

The significance.

Returns:

Qubit

The Qubit with significance $k$.

Raises:

Exception

Tried to retrieve invalid significant from QuantumFloat

Examples

We create a QuantumFloat and flip a qubit of specified significance.

>>> from qrisp import QuantumFloat, x
>>> qf = QuantumFloat(6, -3)
>>> x(qf.significant(-2))
>>> print(qf)
{0.25: 1.0}

The qubit with significance $-2$ corresponds to the value $0.25=2^{-2}$.

>>> x(qf.significant(2))
{4.25: 1.0}

The qubit with significance $2$ corresponds to the value $4=2^2$.
