Complex - Quanty

This page is read only. You can view the source, but not change it. Ask your administrator if you think this is wrong.

====== 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.
###

===== Example =====

###
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//

==== Input ====
<code Quanty 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)
</code>

==== Result ====
<file Quanty_Output>
true
false
</file>
