  • Update the documentation footer to display the package version.

Version 8.9.0 (2025-03-28)#

Features#

  • Reworked the way default gates (operations) are defined so they are decoupled from their implementations. This separation allows for the deletion of default implementations without losing information about its designated name.

  • The majority of the original functionality stays the same.

  • The register_implementation function has been split into several different functions to improve readability and testing, as seen below:

    ``register_implementation``
        |
        v
``register_gate`` --> ``validate_operation`` --> ``compare_operations`` --> ``add_implementation``
                                                                                |
                                                                                v
                                                                      ``validate_implementation`` --> ``set_default``

  • The build_quantum_ops function in builder.py has been split into several functions as well.

  • Trying to modify the implementation class of an existing or default gate implementation yields an error.

Version 8.8.0 (2025-03-28)#

Features#

  • Fixing the rounding issue for rise and fall pulses in ‘Constant_PRX_with_smooth_rise_fall’

Version 8.7.0 (2025-03-27)#

Features#

Version 8.6.0 (2025-03-26)#

Features#

  • A “gate implementation” FluxMultiplexer_SampleLinear which can be used to multiplex several flux pulse gate TimeBoxes together to cancel flux crosstalk.

  • Handle out of locus long-distance VirtualRZ corrections in CZ gates better (scheduling fuses the VirtualRZ corrections to the right IQPulse).

Version 8.5.0 (2025-03-26)#

Bug fix#

  • Fix that injecting a new calibration of an array-valued pulse parameter didn’t work.

Version 8.4.0 (2025-03-21)#

Features#

  • Rename QPU chip types, based on either “crystal” or “star” architecture and number of qubits. For example, “crystal_5” or “star_6”. For “mini” chips, like “mini_crystal_20”, the number is not based on the actual number of qubits but to the chip it’s trying to “minimize” instead, like “crystal_20”. :issue:`SW-1059`

Version 8.3.0 (2025-03-19)#

Bug fixes#

  • Update dependency on exa-common

Version 8.2.0 (2025-03-13)#

Features#

  • added Constant_PRX_with_smooth_rise_fall and RZ_ACStarkShift_smoothConstant pulses, which create a 3-pulse schedule, consisting of rise, constant, and fall pulses. These pulses can have arbitrarily long duration, not limited by the electronics memory.

Version 8.1.0 (2025-02-28)#

Bug fix#

  • Bump exa-common

Version 8.0.0 (2025-02-27)#

Features#

  • Settings refactoring major version

  • Updates to documentation.

  • Replace deprecated usages of DataType.NUMBER with either new DataType.FLOAT or DataType.INT.

Version 7.24.0 (2025-02-20)#

Bug fixes#

  • When registering an already existing gate with iqm-pulse’s register_gate_implementation, the unitary does not need to be equal with the previous unitary (it is impossible to check for this, as they are functions…). If no unitary is provided, the previous unitary is retained.

Version 7.23.0 (2025-02-19)#

Features#

  • Bump python-rapidjson to version 1.20

Version 7.22.0 (2025-02-10)#

Features#

Version 7.21.0 (2025-02-07)#

Features#

  • Adds a new special case to PRX_CustomWaveformsSX for a PRX rotation angle of zero (i.e., identity), in which case a single zero-amplitude pulse with no phase increment is now played. Previously, this special case was not separately considered and two X90 pulses with phase increments were used even though this is unnecessary.

Version 7.20.0 (2025-02-04)#

Features#

  • Refactor codebase to new lint rules. No functional changes. :issue:`SW-467`

Version 7.19.0 (2025-02-04)#

Features#

  • Speed up the calculation of unitaries in CircuitOperationList by caching the reshaping function.

  • The method map_loci() gets an optional argument make_circuit, by default True, which if False will cause the output to be a list of CircuitOperation instead of CircuitOperationList. This is faster and often the circuit with mapped locus is immediately appended to another circuit or converted to TimeBox, neither of which requires the class structure.

  • The method ScheduleBuilder.circuit_to_timebox() has an optional argument locus_mapping, defaulting to an empty dict. If any of the components in the locus of any CircuitOperation is a key in that dict, it is replaced with the value at that key. This speeds up scheduling of identical circuits which only differ by locus.

Bug Fixes#

  • The __add__(), __mul__(), and __getitem__() of CircuitOperationList correctly create the new object by assinging the qubits and table attributes at init, and not after, leading to significant speedup.

Version 7.18.0 (2025-02-04)#

Features#

  • Refactor codebase to new lint rules. No functional changes. :issue:`SW-467`

Version 7.17.0 (2025-02-03)#

Features#

  • CompositeGates now cache their TimeBoxes when possible (cache is flushed whenever ScheduleBuilder.inject_calibration is called)

  • Add GateImplementation documentation.

Version 7.16.0 (2025-02-03)#

Features#

Bug fixes#

  • The calibration validation only compares the calibration data relating to the gate itself, and not any of its registered_gates - those are validated separately anyway whenever they are built. This enables CompositeGate s, which both have their own calibration and registered gates to pass validation.

Version 7.15.0 (2025-01-28)#

Bug fix#

  • Schedule probe pulses in seconds also when the channel granularity is diffrenet for probe vs. drive/flux.

Version 7.14.0 (2025-01-28)#

Features#

Version 7.13.0 (2025-01-28)#

Features#

  • For unitary operations, QuantumOp.unitary is a function which takes the operation’s params and returns the unitary matrix the operation should implement.

  • Add a convenience CircuitOperationList which is an extension of a builtin list, containing CircuitOperation objects. It can be used to easily construct IQM-compatible circuits through shortcuts of syntax similar to qiskit’s QuantumCircuit, only defining qubits and other locus elements once, and using a consistent table of QuantumOps. It can map the locus to some other locus, and be directly used by the ScheduleBuilder to create a schedule.

  • Add a function validate_quantum_circuit() extracting the method ScheduleBuilder.validate_quantum_circuit() so it can be used without the full builder, just using a QuantumOpTable.

  • Add CZ implementations crf_acstarkcrf and slepian_acstarkcrf to the default QuantumOpTable.

  • Bump exa-common.

Version 7.12.0 (2025-01-27)#

Features#

  • Bump version for an updated repo organization. No functional changes. :issue:`SW-1042`

Version 7.11.0 (2025-01-24)#

Features#

  • Disable horizontal scroll from playlist visualisation by default.

  • Add a toggle to enable/disable horizontal scroll.

Version 7.10.0 (2025-01-17)#

Version 7.9.0 (2025-01-08)#

Features#

Version 7.8.0 (2025-01-02)#

Features#

  • Fix that using the measure gate on a system without drive lines didn’t work. :mr:`SW-514`

Version 7.2.0 (2024-12-05)#

Features#

Version 7.1.0 (2024-12-04)#

Features#

  • Bump version for an updated repo organization. No functional changes. :issue:`SW-665`

Version 7.0.0 (2024-11-29)#

Breaking changes#

  • The function apply_move_gate_phase_corrections() no longer uses a calibration set, because the value of the detuning needed for phase tracking of MOVE sandwiches is now a part of the MOVE gate calibration data proper.

Features#

  • Add a parameter detuning to parent class of all MOVE implementations, MOVE_CustomWaveforms. This parameter only affects the frame tracking, and must be set to the difference of the qubit and resonator frequencies.

  • Add this parameter to the MoveMarker instruction.

Bug fixes#

  • Fix the behaviour of U gates: normalization of angle and phases, and pass the correct variable to the schedule in case the RY is realized with two or more phased SX pulses instead of one.

Version 6.14.0 (2024-11-27)#

Features#

  • Add CouplerFluxPulseQubitACStarkPulseGate Pulse, which is a base class for AC Stark pulsed CZ gates.

Version 6.13.0 (2024-11-20)#

Features#

  • measure and reset_wait operations now use explicit Block instructions instead of Wait s inserted by the scheduling algorithm to idle the qubits, since the former is more correct semantically, and will not be disturbed by dynamical decoupling.

Version 6.12.0 (2024-11-19)#

Features#

  • Bump version for an updated repo organization. No functional changes. :issue:`SW-774`

Version 6.11.0 (2024-11-18)#

Bug fixes#

  • Hard box scheduling no longer uses floats anywhere, and does not leak them into the finished schedule.

Version 6.10.0 (2024-11-15)#

Bug fixes#

  • Remove iqm-internal web links in customer docs artifacts.

Version 6.9.0 (2024-11-13)#

Bug fixes#

  • Fix ResetWait gate for computational resonators

Version 6.8.0 (2024-11-12)#

Features#

  • New quantum operation reset_wait and its implementation Reset_Wait which is used for resetting qubits by waiting a time comparable to the relaxation time.

  • All reset implementations now block the common couplers of their locus components.

  • Changes / fixes to playlist visualisation:

    • Wait duration common to all channels at the beginning and end of a segment is truncated and shown as its own block (“Wait at start/end”), making playlists long waits in the beginning / end more comfortable to view.

    • The timeline axis is no longer shown, as it was broken when instructions are truncated (this will be fixed and redisplayed in an upcoming release).

Version 6.7.0 (2024-11-12)#

Bug fixes#

Version 6.6.0 (2024-11-08)#

Features#

Version 6.5 (2024-10-31)#

Bug fixes#

  • Fix scheduling neighborhoods in :meth:.MultiplexedProbeTimeBox.__add__ (affected only Pulla scheduling)

  • Fix probe lines not belonging to settings potentially crashing return parameter discovery

Version 6.4 (2024-10-30)#

  • Update iqm-exa-common to version 25.14.

Version 6.3 (2024-10-30)#

Bug fixes#

  • Measure_Constant now throws an error if the integration weights vector lengths do not match the integration_length. Previously it would propagate the wrong-length vectors to SC normally, where they would lead to nonsensical errors in MCMs & fast feedback

  • cc_prx TimeBoxes now work correctly with Pulla’s measurement multiplexing step (locus components & neighborhoods are adjusted)

  • merge_dicts util did not work correctly with empty lists as the default values (e.g. with integration weights)

Version 6.2 (2024-10-28)#

Features#

  • Add implementation MOVE_CRF_CRF for implementing a move operation using cosine rise fall waveform for coupler and qubit.

  • Add crf_crf implementation to the default operations both for cz and move.

Version 6.1 (2024-10-28)#

  • Update iqm-exa-common to version 25.13 and bump NumPy to version 1.25.2.

Version 6.0 (2024-10-25)#

Breaking changes#

  • Make fast feedback interface more consistent: feedback_label argument in measure and conditional prx renamed to feedback_key (similarly as the measurement key), and conditional_prx has now another argument feedback_qubit, which together form the feedback_label “<feedback_qubit>__<feedback_key>”

Features#

  • In the feedback labels sent to the SC, the feedback key is replaced with a default FEEDBACK_KEY, since the drive AWGs do not yet support multiple different feedback labels. Otherwise using fast feedback and/or resets would be severely limited in circuits. This will be the HW is improved (hopefully soon).

  • Users are no longer able to override default QuantumOp attributes in ymls, other than the implementations and default implementation info

Version 5.9 (2024-10-24)#

  • Update exa-common to 25.12

Version 5.8 (2024-10-21)#

Features#

  • Some cleanup of fast-feedback internals in e.g. ScheduleBuilder, including a fix for the scheduling of the edge-case of many qubits listening to a single feedback bit in parallel.

Version 5.7 (2024-10-16)#

  • Add a general quantum operation for reset and a gate implementation ConditionalReset for feedback-based reset using on a mid-circuit measure gate followed by a classically-controlled PRX gate.

Bug fixes#

  • More fixing of fast feedback in many-to-many target-source cases

Version 5.6 (2024-10-16)#

  • Add a measure gate implementation named “constant_qnd” for mid-circuit measurement operation. This enables optimizing calibration for QNDness and will improve experiments which use many measure gates.

Version 5.5 (2024-10-15)#

Features#

Rename phase_increment_before parameter into PRX(SX) gate into rz_before.

Bug fixes#

  • U gate phase transformation has a wrong sign.

Version 5.4 (2024-10-15)#

Bug fixes#

  • The virtual channels used in fast feedback scheduling no longer block the entire component, allowing more optimal schedules.

  • The conditional gate CCPRX_Composite now schedules correctly when listening to fast feedback from another component to what the conditional flip acts on-

Version 5.3 (2024-10-11)#

Features#

  • Update exa-common to version 25.11.

Version 5.2 (2024-10-11)#

Bug fixes#

  • Fixes wrong sign in phase increment calculation.

  • Bump scipy to 1.11.4.

  • Bump iqm-data-definitions to 2.3 to include documentation of all waveforms.

Version 5.0 (2024-10-08)#

Breaking changes#

  • A new gate implementation base class SinglePulseGate added, and PRX_CustomWaveforms now inherits from this class, which means the _single_iq_pulse method is renamed to _get_pulse (this must be done in all PRX_CustomWaveforms classes). Otherwise the functionality of the method is the same.

  • GateImplementation.construct() removed, and the :meth:GateImplementation.__init__() now fulfills the same purpose construct had before (all inits must have the same signature).

Features#

  • GateImplementation.__call__() now handles TimeBox caching and the users do not have to implement it in every gate implementation separately. Instead you can now just override GateImplementation._call() if you are satisfied with caching based on the call arguments.

Version 4.0 (2024-10-02)#

Breaking changes#

  • ConditionalPRX renamed to CCPRX_Composite which now requires calibration for signal delays.

Features#

  • a GateImplementation can now return an list of timeboxes, to be used in cases where the relative timing of instructions is less strict.

  • Measure_Constant now accepts an empty array for the integration weights, signifying constant weigths. Use empty array instead of None.

  • Canonical waveforms are no longer defined via inheritable class property, but instead by a static whitelist. Now you can inherit from a canonical waveform without issues. :issue:`EXA-2112`

Features#

  • Added GateImplementation.get_custom_locus_mapping() which allows the gate implementations to define their own locus mappings, making it possible to write the entire logic of an implementation inside its class definition, :issue:`EXA-1831`

  • GateImplementation now has a bool attribute special_implementation, which can be set as True if the implementation is a special purpose implementation that should never get called in :meth:ScheduleBuilder.get_implementation unless explicitly requested via the impl_name argument. - Special implementations cannot be set as default implementations in QuantumOp.

Version 3.1 (2024-09-11)#

Features#

  • Update exa-common.

Version 3.0 (2024-09-06)#

Features#

  • New gate implementations in PRX using \(\pi/2\) pulse: PRX_DRAGGaussianSX and PRX_DRAGCosineRiseFallSX, which inherits from PRX_CustomWaveformsSX. The default implementation names are drag_crf_sx and drag_gaussian_sx.

  • New U gate UGate using composition \(Z(\phi)Y(\theta)Z(\lambda)\), with PRX gate \(Y(\theta)\). This gate will use the same implementation as PRX gate. The default gate name is u, and implementation name prx_u

  • New sqrt(X) gate SXGate using fixed pulse \(X(\pi/2)\), from PRX gate. The default gate name is sx, and implementation name prx_sx.

Breaking changes#

  • PRX gate attribute x_pi and classmethod _x_pi_pulse() renamed to iq_pulse and _single_iq_pulse().

Version 2.8 (2024-08-22)#

Features#

  • QuantumOp.get_default_implementation_for_locus() returns the locus-specific default for a permutation of a symmetric gate’s locus, making the behaviour more consistent with other functionalities of ScheduleBuilder.
