pygsti.modelmembers.povms.staticeffect

The StaticPOVMEffect class and supporting functionality.

Module Contents

Classes

StaticPOVMEffect

A POVM effect vector that is completely fixed, or "static" (i.e. that posesses no parameters).

class pygsti.modelmembers.povms.staticeffect.StaticPOVMEffect(vec, basis=None, evotype='default', state_space=None)

Bases: pygsti.modelmembers.povms.conjugatedeffect.ConjugatedStatePOVMEffect

A POVM effect vector that is completely fixed, or “static” (i.e. that posesses no parameters).

Parameters

vecarray_like or POVMEffect

a 1D numpy array representing the POVM effect. The shape of this array sets the dimension of the POVM effect.

evotypeEvotype or str, optional

The evolution type. The special value “default” is equivalent to specifying the value of pygsti.evotypes.Evotype.default_evotype.

state_spaceStateSpace, optional

The state space for this operation. If None a default state space with the appropriate number of qubits is used.

Initialize a new POVM effect Vector

set_dense(vec)

Set the dense-vector value of this POVM effect vector.

Attempts to modify this POVM effect vector’s parameters so that the raw POVM effect vector becomes vec. Will raise ValueError if this operation is not possible.

Parameters
vecarray_like or POVMEffect

A numpy array representing a POVM effect vector, or a POVMEffect object.

Returns

None
