qermit.postselection#

postselect_mitres.gen_postselect_mitres(postselect_mgr: PostselectMgr, **kwargs) → MitRes#

Generates MitRes running given circuit and applying postselection.

Parameters:

Returns:

MitRes running given circuit and applying postselection.

Return type:

class qermit.postselection.postselect_manager.PostselectMgr(compute_cbits: List[Bit], postselect_cbits: List[Bit])[source]#

Class for tracking and applying post selection to results. Includes other methods to analyse the results after post selection.

__init__(compute_cbits: List[Bit], postselect_cbits: List[Bit])[source]#

Initialisation method.

Parameters:

compute_cbits (List[Bit]) – Bits in the circuit which are not affected by post selection.
postselect_cbits (List[Bit]) – Bits on which the post selection is based.

Raises:

Exception – Raised if a bit is in both compute_cbits and postselect_cbits.

dict_to_result(result_dict: Dict[Tuple[int, ...], int]) → BackendResult[source]#

Convert dictionary to BackendResult.

Parameters:: result_dict (Dict[Tuple[int, ...], int]) – Dictionary to convert.
Returns:: Corresponding BackendResult.
Return type:: BackendResult

get_postselected_shot(shot: Tuple[int, ...]) → Tuple[int, ...][source]#: Removes postselection bits from shot.

is_postselect_shot(shot: Tuple[int, ...]) → bool[source]#: Determines if shot survives postselection

merge_result(result: BackendResult) → BackendResult[source]#

Transforms BackendResult so that postselection bits are removed, but no shots are removed by postselection.

postselect_result(result: BackendResult) → BackendResult[source]#

Transforms BackendResult to keep only shots which should be post selected.
