merlin.measurement.strategies module

Measurement strategy definitions for quantum-to-classical conversion.

enum merlin.measurement.strategies.Enum(value)

Bases: object

Create a collection of name/value pairs.

Example enumeration:

>>> class Color(Enum):
...     RED = 1
...     BLUE = 2
...     GREEN = 3

Access them by:

• attribute access:

  >>> Color.RED
  <Color.RED: 1>
  

• value lookup:

  >>> Color(1)
  <Color.RED: 1>
  

• name lookup:

  >>> Color['RED']
  <Color.RED: 1>
  

Enumerations can be iterated over, and know how many members they have:

>>> len(Color)
3

>>> list(Color)
[<Color.RED: 1>, <Color.BLUE: 2>, <Color.GREEN: 3>]

Methods can be added to enumerations, and members can have their own attributes – see the documentation for details.

The Enum and its members have the following methods:

name

The name of the Enum member.

value

The value of the Enum member.

enum merlin.measurement.strategies.MeasurementStrategy(value)

Bases: Enum

Strategy for measuring quantum states or counts and possibly apply mapping to classical outputs.

Valid values are as follows:

PROBABILITIES = <MeasurementStrategy.PROBABILITIES: 'probabilities'>

MODE_EXPECTATIONS = <MeasurementStrategy.MODE_EXPECTATIONS: 'mode_expectations'>

AMPLITUDES = <MeasurementStrategy.AMPLITUDES: 'amplitudes'>
