mm.lab.Homodyne¶

class mrmustard.lab.Homodyne(quadrature_angle, result=None, modes=None, r=None)[source]¶

Homodyne measurement on given modes. If result is not provided then the value is sampled.

Parameters:

quadrature_angle (float or List[float]) – measurement quadrature angle
result (optional float or List[float]) – displacement amount
modes (optional List[int]) – the modes of the displaced squeezed state
r (optional float or List[float]) – squeezing amount (default: settings.HOMODYNE_SQUEEZING)

Attributes

`modes`	returns the modes being measured
`num_modes`	returns the number of modes being measured
`outcome`	Returns outcome of the measurement.
`parameter_set`	The set of parameters for this transformation.
`postselected`	returns whether the measurement is postselected, i.e, a outcome has been provided

postselected¶: returns whether the measurement is postselected, i.e, a outcome has been provided

performs the measurement procedure according to the representation of the incoming state
