SamplerExecutionOptionsV2
class SamplerExecutionOptionsV2(init_qubits=Unset, rep_delay=Unset, meas_type=Unset)
Bases: ExecutionOptionsV2
Extension of ExecutionOptionsV2
for the sampler primitive.
Attributes
Parameters
- init_qubits (UnsetType | bool)
- rep_delay (UnsetType | float)
- meas_type (UnsetType | Literal['classified', 'kerneled', 'avg_kerneled'])
init_qubits
Type: UnsetType | bool
Default value: Unset
Whether to reset the qubits to the ground state for each shot. Default is True
.
meas_type
Type: UnsetType | Literal['classified', 'kerneled', 'avg_kerneled']
Default value: Unset
How to process and return measurement results.
This option sets the return type of all classical registers in all SamplerPubResult
s. If a sampler pub with shape pub_shape
has a circuit that contains a classical register with size creg_size
, then the returned data associated with this register will have one of the following formats depending on the value of this option.
"classified"
: ABitArray
of shapepub_shape
overnum_shots
with a number of bits equal tocreg_size
."kerneled"
: A complex NumPy array of shape(*pub_shape, num_shots, creg_size)
, where each entry represents an IQ data point (resulting from kerneling the measurement trace) in arbitrary units."avg_kerneled"
: A complex NumPy array of shape(*pub_shape, creg_size)
, where each entry represents an IQ data point (resulting from kerneling the measurement trace and averaging over shots) in arbitrary units. This option is equivalent to selecting"kerneled"
and then averaging over the shots axis, but requires less data bandwidth.
Default: “classified”.
See here for a description of kerneling.
rep_delay
Type: UnsetType | float
Default value: Unset
The repetition delay. This is the delay between a measurement and the subsequent quantum circuit. This is only supported on backends that have backend.dynamic_reprate_enabled=True
. It must be from the range supplied by backend.rep_delay_range
. Default is given by backend.default_rep_delay
.
