class
MeasureThreshold
(select=None)[source]¶ Bases:
strawberryfields.ops.Measurement
Measures a set of modes with thresholded Fock-state measurements, i.e., measuring whether a mode contain zero or nonzero photons.
After measurement, the modes are reset to the vacuum state.
Attributes
Extra dependencies due to parameters that depend on measurements.

measurement_deps
¶ Extra dependencies due to parameters that depend on measurements.
- Returns

- Return type
set[RegRef]

= None¶
Methods
apply
(reg, backend, **kwargs)Ask a backend to execute the operation on the current register state right away.
decompose
(reg, **kwargs)Decompose the operation into elementary operations supported by the backend API.
merge
(other)Merge the operation with another (acting on the exact same set of subsystems).
-
apply
(reg, backend, **kwargs)¶ Ask a backend to execute the operation on the current register state right away.
Like
Operation.apply()
, but also stores the measurement result in the RegRefs.- Keyword Arguments
shots (int) – Number of independent evaluations to perform. Only applies to Measurements.
-
decompose
(reg, **kwargs)¶ Decompose the operation into elementary operations supported by the backend API.
See
strawberryfields.backends.base
.
-
merge
(other)¶ Merge the operation with another (acting on the exact same set of subsystems).
Note
For subclass overrides: merge may return a newly created object, or self, or other, but it must never modify self or other because the same Operation objects may be also used elsewhere.
- Parameters
other (Operation) – operation to merge this one with
- Returns
other * self. The return value None represents the identity gate (doing nothing).
- Return type
Operation, None
- Raises
MergeFailure – if the two operations cannot be merged
