sf.physics.gaussian.two_mode_squeezed_vacuum_cov

mrmustard.physics.gaussian.two_mode_squeezed_vacuum_cov(r, phi)[source]

Returns the real covariance matrix and real means vector of a two-mode squeezed vacuum state.

The dimension depends on the dimensions of r and phi.

Parameters:
  • r (vector) – squeezing magnitude

  • phi (vector) – squeezing angle

Returns:

two-mode squeezed state covariance matrix Vector: two-mode squeezed state means vector

Return type:

Matrix
