- mrmustard.physics.fock.quadrature_distribution(state, quadrature_angle=0.0, x=None)[source]¶
Given the ket or density matrix of a single-mode state, it generates the probability density distribution \(\tr [ \rho |x_\phi><x_\phi| ]\) where rho is the density matrix of the state and |x_phi> the quadrature eigenvector with angle phi equal to
quadrature_angle
.- Parameters:
state (Tensor) – single mode state ket or density matrix
quadrature_angle (float) – angle of the quadrature basis vector
x (Vector) – points at which the quadrature distribution is evaluated
- Returns:
coordinates at which the pdf is evaluated and the probability distribution
- Return type:
tuple(Vector, Vector)
