sf.physics.gaussian.squeezed_vacuum_cov

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

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

The dimension depends on the dimensions of r and phi.

Parameters:
  • r (vector) – squeezing magnitude

  • phi (vector) – squeezing angle

Returns:

thermal state covariance matrix or means vector

Return type:

Matrix, Vector
