new torontonian sampling #248

Closed jakeffbulmer closed 3 years ago

jakeffbulmer commented 3 years ago

Context: the old torontonian sampling function using tor, and so could not be used for states with displacement. It was also a little clumsy.

Description of the Change: The function now calls threshold_detection_prob, making the code a bit cleaner and importantly also allows for displaced Gaussian states to be sampled from.

Benefits: Cleaner code, nonzero displacement now allowed.

Possible Drawbacks: We could do some clever things to speed it up slightly.
