PyQASM 1.0.0

Release 1.0.0 (September 19, 2025)

Summary

Added

• ❗Major Update ❗
  Added support for OPENPULSE code in pyqasm. (#246)

  Supported example program:

  OPENQASM 3.0;
  defcalgrammar "openpulse";
    
  complex[float[32]] amp = 1.0 + 2.0im;
  cal {
      port d0;
      frame driveframe = newframe(d0, 5.0e9, 0.0);
      waveform wf = gaussian(amp, 16ns, 4ns);
  }
    
  const float frequency_start = 4.5e9;
  const float frequency_step = 1e6;
  const int frequency_num_steps = 3;
  
  defcal saturation_pulse $0 {
      play(driveframe, constant(amp, 100e-6s));
  }
    
  cal {
      set_frequency(driveframe, frequency_start);
  }
    
  for int i in [1:frequency_num_steps] {
      cal {
          shift_frequency(driveframe, frequency_step);
      }
      saturation_pulse $0;
  }

• Added a workflow to track changes in the docs/_static/logo.png file to prevent unnecessary modifications. (#257)
• Added decomposition details for all gates in the docs/gate_decompositions.md file. (#237)

Improved / Modified

• Modified if statement validation to now include empty blocks as well. See Issue #246 for details. (#251)
