Complex

boolean, read only

For a wavefunction psi, psi.Complex returns a boolean (true or false) stating if the wavefunction contains complex numbers or not.

We can define the functions $$|\psi\rangle = \left(\frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_1 + \frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_2 + (1+I)\frac{1}{\sqrt{4}} a^{\dagger}_1 a^{\dagger}_2 \right)|0\rangle,$$ and $$|\psi\rangle = \left(\frac{1}{\sqrt{2}} a^{\dagger}_0 a^{\dagger}_1 + \frac{1}{\sqrt{2}} a^{\dagger}_0 a^{\dagger}_2 \right)|0\rangle.$$

For the former psi.Complex() is true for the later psi.Complex() is false

Example.Quanty

NF=3
NB=0
psi = NewWavefunction(NF, NB, {{"110",sqrt(1/4)},{"101",sqrt(1/4)},{"011",(1+I)*sqrt(1/4)}})
print(psi.Complex)
psi = NewWavefunction(NF, NB, {{"110",sqrt(1/2)},{"101",sqrt(1/2)}})
print(psi.Complex)

true
false
