qoqo.operations.PragmaSleep

class qoqo.operations.PragmaSleep

This PRAGMA operation makes the quantum hardware wait a given amount of time.

This PRAGMA operation is used for error mitigation reasons, for instance. It can be used to boost the noise on the qubits since it gets worse with time.

Parameters:

qubits (list[int]) – The qubits involved in the sleep block.
sleep_time (CalculatorFloat) – The time for the execution of the block in seconds.

__init__()

Methods

`__init__`()
`hqslang`()	Returns hqslang name of Operation
`involved_qubits`()	List all involved Qubits
`is_parametrized`()	Returns true if operation contains symbolic parameters
`qubits`()	Return list of qubits of the multi qubit operation in order of descending significance
`remap_qubits`(mapping)	Remap qubits
`sleep_time`()	Returns value of attribute sleep_time
`substitute_parameters`(substitution_parameters)	Substitutes internal symbolic parameters with float values
`tags`()	Returns tags identifying the Operation

hqslang()

Returns hqslang name of Operation

Returns:: The name
Return type:: str

involved_qubits()

List all involved Qubits

Returns:: The involved qubits as a set or ‘ALL’ if all qubits are involved
Return type:: Union[set[int], str]

is_parametrized()

Returns true if operation contains symbolic parameters

Returns:: bool

qubits()

Return list of qubits of the multi qubit operation in order of descending significance

Returns:: list[int]

remap_qubits(mapping)

Remap qubits

Parameters:: mapping (dict[int, int]) – The mapping
Returns:: The operation with the remapped qubits
Return type:: Operation
Raises:: RuntimeError – Qubit remapping failed

sleep_time(): Returns value of attribute sleep_time

substitute_parameters(substitution_parameters)

Substitutes internal symbolic parameters with float values

Only available when all symbolic expressions can be evaluated to float with the provided parameters.

Parameters:: substitution_parameters (dict[str, float]) – The substituted free parameters
Returns:: The operation with the parameters substituted
Return type:: Operation
Raises:: RuntimeError – Parameter Substitution failed

tags()

Returns tags identifying the Operation

Returns:: The tags identifying the operation
Return type:: list[str]
