pygsti.modelmembers.operations.krausop.KrausOperatorInterface#

class KrausOperatorInterface#

Bases: object

Adds an interface for extracting the Kraus operator(s) of an operation (quantum map).

Methods

`__init__`()
`from_kraus_operators`(kraus_operators[, ...])	Create an operation by specifying its Kraus operators.
`set_kraus_operators`(kraus_operators)	Set the parameters of this operation by specifying its Kraus operators.

Attributes

`kraus_operators`	A list of this operation's Kraus operators as numpy arrays.
`num_kraus_operators`	The number of Kraus operators in the Kraus decomposition of this operation.

classmethod from_kraus_operators(kraus_operators, basis='pp', evotype='default', state_space=None)#

Create an operation by specifying its Kraus operators.

Parameters:

kraus_operators (list) – A list of numpy arrays, each of which specifyies a Kraus operator.
basis (str or Basis, optional) – The basis in which the created operator’s superoperator representation is in.
evotype (Evotype or str, optional) – The evolution type. The special value “default” is equivalent to specifying the value of pygsti.evotypes.Evotype.default_evotype.
state_space (StateSpace, optional) – The state space for this operation. If None a default state space with the appropriate number of qubits is used.

set_kraus_operators(kraus_operators)#

Set the parameters of this operation by specifying its Kraus operators.

Parameters:: kraus_operators (list) – A list of numpy arrays, each of which specifyies a Kraus operator.
Return type:: None

property kraus_operators#: A list of this operation’s Kraus operators as numpy arrays.

property num_kraus_operators#: The number of Kraus operators in the Kraus decomposition of this operation.
