qupulse 0.10

Features

• Move HDAWG driver to qupulse-hdawg-legacy to disentangle driver version from qupulse version. The new HDAWG driver will be published under qupulse-hdawg. (#779)
• Add the ProgramBuilder interface pattern to make the generated program of PulseTemplate.create_program easily customizable. (#781)
• Measurement windows can now automatically shrank in case of overlap to counteract small numeric errors. (#791)

Bugfixes

• ConstantPulseTemplates from all versions can now be deserialized. (#696)
• Fixed that single segment tables where always interpreted to be constant. (#707)
• Add missing pulse registry support to ArithmeticPT. (#775)

Release 0.9

Features

• Add __pow__ as a repetition shortcut. This means you can do my_pulse_template ** 5 or my_pulse_template ** 'my_repetition_count'. (#692)
• Promote qupulse.expression to a subpackage and create qupulse.expression.protocol with protocol classes that define the expression interface that is supposed to be used by qupulse. The sympy based implementation is moved to qupulse.expressions.sympy and imported in qupulse.expressions.
• The intended use is to be able to use less powerful but faster implementations of the Expression protocol where appropriate. In this first iteration, qupulse still relies on internals of the sympy based implementation in many places which is to be removed in the future. (#750)
• Promote parts of the private subpackage qupulse._program to the public subpackage qupulse.program, i.e. loop, volatile, transformation and waveforms. This allows external packages/drivers to rely on stability of the Loop class. (#779)
• Add PulseTemplate.pad_to method to help padding to minimal lengths or multiples of given durations. (#801)

Misc

• Fix Loop repr #771

Release 0.8

qupulse 0.8 (2023-03-28)

Features

• New two dimensional plotting function qupulse.pulses.plotting.plot_2d. (#703 <https://github.com/qutech/qupulse/issues/703>_)
• Add support for time dependent expressions for arithmetics with atomic pulse templates i.e. ParallelChannelPT and
  ArithmeticPT support time dependent expressions if used with atomic pulse templates.
  Rename ParallelConstantChannelPT to ParallelChannelPT to reflect this change. (#709 <https://github.com/qutech/qupulse/issues/709>_)
• Add with_ family of helper methods to PulseTemplate to allow convinient and easily discoverable pulse template
  combination. (#710 <https://github.com/qutech/qupulse/issues/710>_)
• The plotting module is now located at qupulse.plotting. There is a legacy alias at qupulse.pulses.plotting. (#735 <https://github.com/qutech/qupulse/issues/735>_)

Deprecations and Removals

• Remove the Parameter, MappedParameter and ConstantParameter classes that where deprecated in version 0.5. (#512 <https://github.com/qutech/qupulse/issues/512>_)
• Drop support for python version 3.7. (#760 <https://github.com/qutech/qupulse/issues/760>_)

qupulse 0.7

qupulse 0.7 (2022-10-05)

Features

• Add optional numba uses in some cases. (#501)

• Add initial_values and final_values attributes to PulseTemplate.

  This allows pulse template construction that depends on features of arbitrary existing pulses i.e. like extension until
  a certain length. (#549)

• Support sympy 1.9 (#615)

• Add option to automatically reduce the sample rate of HDAWG playback for piecewise constant pulses.
  Use qupulse._program.seqc.WaveformPlayback.ENABLE_DYNAMIC_RATE_REDUCTION to enable it. (#622)

• Add a TimeReversalPT. (#635)

• Add specialied parameter Scope for ForLoopPT. This increases performance by roughly a factor of 3 for long ranges! (#642)

• Add sympy 1.10 support and make ExpressionVector hashable. (#645)

• Serializable is now comparable via it's get_serialized_data. PulseTemplate implements Hashable via the same. (#653)

• Add an interface that uses atsaverage.config2. (#686 #686`_)

Bugfixes

• floor will now return an integer in lambda expressions with numpy to allow usage in ForLoopPT range expression. (#612)

Deprecations and Removals

• Drop cached_property dependency for python>=3.8. (#638)
• Add frozendict dependency to replace handwritten solution. Not having it installed will break in a future release
  when the old implementation is removed. (#639)
• Drop python 3.6 support. (#656)

qupulse 0.6

qupulse 0.6 (2021-07-08)

Features

• Add [evaluate_with_exact_rationals]{.title-ref} method to
  [ExpressionScalar]{.title-ref}
  (#546)
• New feature based AWG abstraction. Can be found in
  [qupulse.hardware.feature_awg]{.title-ref}. Allows easier code reuse
  across awg drivers.
  (#557)
• Add ConstantPulseTemplate
  (#565)
• Add interface to use [atsaverage]{.title-ref} auto rearm
  (#566)
• Adds the methods [is_constant]{.title-ref},
  [constant_value_dict]{.title-ref} and [constant_value]{.title-ref}
  to Waveform class to allow more efficient AWG usage.
  (#588)

Bugfixes

• Fix TimeType comparisons with non-finite floats (inf, -inf, NaN)
  (#536)

Improve alazar usability:

:   -   Do not touch the default config when arming a measurement
    -   Keep current config in a seperate field
    -   Extend record to a multiple of a configurable value (4KB by
        default)
        ([\#571](https://github.com/qutech/qupulse/issues/571))

• Replace pytabor and teawg with tabor_control to support
  newer(>=1.11) pyvisa versions
  (#599)

• Fix [repr]{.title-ref} of [ExpressionScalar]{.title-ref} when
  constructed from a sympy expression. Also replace
  [Expression]{.title-ref} with [ExpressionScalar]{.title-ref} in
  [repr]{.title-ref}.
  (#604)

Deprecations and Removals

• Deprecate HashableNumpyArray due to its inconsistency.
  (#408)
• Drop support for python 3.5
  (#504)
• Remove deprecated [external_parameters]{.title-ref} keyword argument
  from SequencePT and AtomicMultiChannelPT
  (#592)
• Deprecate boolean [duration]{.title-ref} argument of
  [AtomicMultiChannelPulseTemplate]{.title-ref} and remove duration
  check in [__init__]{.title-ref}.
