qrisp.QuantumFloat.get_ev#
- QuantumFloat.get_ev(**mes_kwargs)[source]#
Retrieves the expectation value of self.
- Parameters:
- **mes_kwargsdict
Keyword arguments for the measurement. See
qrisp.QuantumVariable.get_measurement()
for more information.
- Returns:
- float
The expectation value.
Examples
We set up a QuantumFloat in uniform superposition and retrieve the expectation value:
>>> from qrisp import QuantumFloat, h >>> qf = QuantumFloat(4) >>> h(qf) >>> qf.get_ev() 7.5
