ProbDistribution

class ProbDistribution(data, shots=None)

Bases: dict

A generic dict-like class for probability distributions.

Builds a probability distribution object.

Parâmetros

• 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.

Levanta

• 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]
