ProbDistribution

class ProbDistribution(data, shots=None)[fuente]

Bases: dict

A generic dict-like class for probability distributions.

Builds a probability distribution object.

Parámetros
  • data (dict) –

    Input probability data. Where the keys represent a measured classical value and the value is a float for the probability of that result. The keys can be one of several formats:

    • A hexadecimal string of the form "0x4a"

    • A bit string e.g. '0b1011' or "01011"

    • An integer

  • shots (int) – Number of shots the distribution was derived from.

Muestra
  • TypeError – If the input keys are not a string or int

  • ValueError – If the string format of the keys is incorrect

Methods

binary_probabilities

Build a probabilities dictionary with binary string keys

clear

copy

fromkeys

Create a new dictionary with keys from iterable and values set to value.

get

Return the value for key if key is in the dictionary, else default.

hex_probabilities

Build a probabilities dictionary with hexadecimal string keys

items

keys

pop

If key is not found, d is returned if given, otherwise KeyError is raised

popitem

Remove and return a (key, value) pair as a 2-tuple.

setdefault

Insert key with a value of default if key is not in the dictionary.

update

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]
