Release Notes
Release 2.56.0
Release date 17.07.2025
Requires: LabOne 25.04
Includes: Applications Library 2.10.0
Notes & Important Changes
Functionality
- The
get_edges
method now supports retrieving all edges in the QPU topology by allowing thenode
parameter to beNone
. - Improved error diagnostics by adding contextual information to compilation failures. When code generation fails for an AWG, error messages now include the specific signal UIDs that were being processed.
- The OpenQASM
batch_experiment
method andexp_from_qasm_list
functions no longer pad each experiment to a fixed length by default. Previously therepetition_time
option had to be set to a suitable time to ensure each chunk was the same length when using the experiment-chunking feature (batch_execution_mode="pipeline"
). This is no longer required, so nowrepetition_time
defaults toNone
, which adds no padding.
Note
LabOne Q has ended support and testing for Python version 3.9 with version 2.53. Please make sure to upgrade your Python environments to a supported version before upgrading.
Note
Including the instrument options when constructing the DeviceSetup
is now a strict requirement since version 2.52.0.
Specify your instrument configuration through either the 'options' field in the 'instruments' list when using a device setup descriptor,
or by specifying the device_options
argument when constructing your setup programmatically.
Alternatively, you can use the generate_device_setup
helper function available under contrib
,
which has the option to query the instruments for installed options automatically.
This function is already used in the majority of our publicly available examples.
Applications Library
- Added support for temporary edge parameters in QPU parameter updating, allowing modification of topology edge parameters using tuple keys in addition to existing quantum element parameter updates.
Deprecation notice
Note
The deprecated Results.compiled_experiment
attribute has been removed.
Note
The Qubit
and Transmon
classes are not yet considered stable and their APIs might still change in future versions.
Their parent QuantumElement
class has been updated with version 2.44, making it much simpler to create your own implementation of a qubit object.
Note
The temporary_modify
task from the Applications library has been deprecated. Please use temporary_qpu
and, if needed,
temporary_quantum_elements_from_qpu
instead.
Bug Fixes
- Fixed a bug where explicitly specifying
PortMode.RF
prevented enabling auto-muting. - Fixed the serialization of
TWPAParamter
by allowingTWPAParameter.cancellation_source
to accept string values. - Fixed a bug that had broken the temporary modification of quantum-element parameters in the experiment workflows in the Applications Library. The bug was caused by an incorrect QPU argument being passed to the
temporary_quantum_elements_from_qpu
task.
Documentation
- Removed
repetition_time
option from the examples in the VQE and Randomized Benchmarking Qiskit how-to guides, since it is no longer required. - Fixed typo in documentation navigation and improved QPU topology tutorial formatting by removing numbered section headers and updating parameter names for better clarity.
- Updated the temporary parameters section of the Experiment Workflows tutorial to show that parameters for both quantum elements and topology edges can be temporarily modified.
- Removed deprecated zsync parameter from device setup configurations in tutorial notebooks.
Known Issues
- Using
OpenQASMTranspiler.batch_experiment
with QASM programs that contain native measurement operations will lead to an unexpected shape of the returned data. To ensure the correct shape, measurement operations should be removed from the OpenQASM program, and.batch_experiment
should be called with the option fieldadd_measurement=True
, which will add the measurement operations to the LabOne QExperiment
during the import step (see our tutorial for more details). - Using the internal scope to acquire raw traces on multiple channels of an SHFQA in a single experiment is only possible if the timing of all acquisitions is equal between instrument channels.
- Using runtime checks of the sequencer playback through the
disable_runtime_checks=False
argument ofsession.connect()
, is currently not possible when the experiment contains real-time feedback or is using the on-device PRNG. In the latter case, unintended error messages may be produced if the option is used. - When using the pipeliner in an experiment by specifying a
chunk_count
parameter in a sweep, the number ofacquire
commands in each chunk currently needs to be equal. Typically this means that the number of sweep steps within each chunk has to be the same. - When using
OutputSimulator
or pulse sheet viewer with an experiment using the pipeliner or near-time sweeping, currently only the first sequence step will be displayed. - When delaying logical signal lines of type
rf_signal
via thedelay_signal
calibration property, all rf_signals on the same sequencer core must be set to the same delay. - When delaying logical signal lines on the SHFQA via the
delay_signal
calibration property, the delays for the measure and acquire line must be the same; the measure pulse delay is not added to the acquire pulse delay as on the UHFQA. We recommend to useport_delay
for now. - When creating a section with very short content (below the device’s minimum waveform length), the compiler may fail to map the experiment to valid SeqC, and will generate an error. As a workaround in these cases, manually add delays to the sequence.
