qrisp.QuantumFloat.exp_shift#

QuantumFloat.exp_shift(shift: int) → None[source]#

Performs an internal bit shift.

Note that this method doesn’t cost any quantum gates. For the quantum version of this method, see quantum_bit_shift.

Parameters:

shiftint: The amount to shift.

Raises:

TypeError: Tried to shift QuantumFloat exponent by non-integer value

Examples

We create a QuantumFloat and perform a bitshift:

>>> from qrisp import QuantumFloat
>>> a = QuantumFloat(4)
>>> a[:] = 2
>>> a.exp_shift(2)
>>> print(a)
{8: 1.0}
>>> print(a.qs)
