  • If possible, make a PR with a failing test to give us a starting point to work on!
Describe the bug

reset operation is not being passed properly between CUDA-Q and IQM

Steps to reproduce the bug

if stim is changed to iqm hardware in this tutorial above, we get the following error:

"error: 'quake.reset' op unable to translate op to IQM Json quake.reset" coming from the line "dem = qec.z_dem_from_memory_circuit(surface_code, statePrep, nRounds)"

side note: the simulation uses a noise model which we believe is automatically removed when executed on hardware

Expected behavior

NA

Is this a regression? If it is, put the last known working version (or commit) here.

Not a regression

Environment

  • Python version:
  • C++ compiler:
  • Operating system:

Research direction

Start by reproducing the circuit-level-noise tutorial with the target changed from stim to iqm, then trace qec.z_dem_from_memory_circuit(surface_code, statePrep, nRounds) and the quake.reset translation error. The work is done when the reset operation is passed in IQM JSON without the reported translation failure; the issue does not name a source file or test.
