Release v0.20.0

Main changes

• Reworking the NoiseModel interface (#710)
• Allow modification of the EOM setpoint without disabling EOM mode (#708)
• Enable definition of effective noise operators in all basis (#716)
• Add leakage (#720)
• Support differentiability through Torch tensors (#703)
• Add from_abstract_repr to Device and VirtualDevice (#727)
• [FEAT] Handle batches with partial results (#707)
• Add open batches to pulser-pasqal (#701)

Deprecations

• With the new NoiseModel interface, noise_types should no longer be explicitly provided and the default values are removed. Instead, only the relevant noise parameters should be provided and the associated noise types are activated accordingly.
• With the addition of open batches, all references to "submission" as an identifier of a batch were replaced by "batch". This forced some deprecations, namely:
  • RemoteResults(submission_id:str, ...) is now RemoteResults(batch_id: str, ...)
  • RemoteResults.get_status() -> SubmissionStatus is deprecated in favor of RemoteResults.get_batch_status() -> BatchStatus

All changes were introduced in a backwards compatible way.

• Fix simulation of SPAM noise in XY in QutipEmulator. (#649)

Changelog

b50a378 FIX: SPAM noise in XY, Slope of RampWaveform (#649)

Release v0.17.0

Main Changes

• Clarify confusion between kraus operators and collapse operators (#616): Simulations with noise channels now uniformly use collapse operators and rates, while the usage of Kraus operators and probabilities has been deprecated.

• Support standalone serialization of Register and RegisterLayout to the abstract representation (#627): These objects can now be serialized to and deserialized from the abstract representation on their own through their to_abstract_repr() and from_abstract_repr() methods.

• Hashing for coordinate collections (#627): Register now have an idempotent hash based exclusively on their coordinates (accessible through BaseRegister.coords_hash())

• Explicitly define public symbols for all modules (#630): All classes needed for a standard usage of Pulser are now accessible through the top-level pulser namespace. This gives the option of trading code looking like this

  from pulser import Pulse, Register, Sequence
  from pulser.devices import MockDevice
  from pulser.waveforms import BlackmanWaveform, RampWaveform
  
  reg = Register.square(4)
  seq = Sequence(reg, MockDevice)
  
  pulse = Pulse(
      amplitude=BlackmanWaveform(1000, 3.14),
      detuning=RampWaveform(1000, -10, 10),
      phase=0,
  )

  for this

  import pulser
  
  reg = pulser.Register.square(4)
  seq = pulser.Sequence(reg, pulser.MockDevice)
  
  pulse = pulser.Pulse(
      amplitude=pulser.BlackmanWaveform(1000, 3.14),
      detuning=pulser.RampWaveform(1000, -10, 10),
      phase=0,
  )

Deprecations

• In NoiseModel and SimConfig, dephasing_prob, depolarizing_prob and eff_noise_probs have been deprecated in favour of dephasing_rate, depolarizing_rate and eff_noise_rates.
• Register.rotate() has been deprecated. The new and preferred Register.rotated() method returns a new register instance with the rotated coordinates instead of changing them in place.
