cirq.Sweep

class cirq.Sweep

A sweep is an iterator over ParamResolvers.

A ParamResolver assigns values to Symbols. For sweeps, each ParamResolver

must specify the same Symbols that are assigned. So a sweep is a way to

iterate over a set of different values for a fixed set of Symbols. This is

useful for a circuit, where there are a fixed set of Symbols, and you want

to iterate over an assignment of all values to all symbols.

For example, a sweep can explicitly assign a set of equally spaced points

between two endpoints using a Linspace,

sweep = Linspace(“angle”, start=0.0, end=2.0, length=10)

This can then be used with a circuit that has an ‘angle’ Symbol to

run simulations multiple simulations, one for each of the values in the

sweep

result = simulator.run_sweep(program=circuit, params=sweep)

Sweeps support Cartesian and Zip products using the ‘*’ and ‘+’ operators,

see the Product and Zip documentation.

__init__()

Initialize self. See help(type(self)) for accurate signature.

Methods

param_tuples()

An iterator over (key, value) pairs assigning Symbol key to value.

Attributes

keys	The keys for the all of the Symbols that are resolved.
