Stabilizer simulation example utilizing stim backend #211

Closed refraction-ray closed 3 weeks ago

refraction-ray commented 1 month ago

Task description

Add an example python script stabilizer_stim_sim.py in /examples which showcases stabilizer circuit simulation using tc interface with stim backend.

Implementation

The script includes:

  1. Clifford circuit with mid-circuit measurement defined in tc
  2. Transform the circuit object into Stim circuit object with the helper function defined in the same script (input: tc circuit, output: stim circuit)(can utilize c._qir and c._extra_qir, using c.measure_instruction to get the mid circuit measurement recorded in extra_qir and using c.mid_measurement for the real functionality)
  3. Simulate the circuit in stim and extract the stabilizer tableau
  4. Compute the entanglement entropy of the output state with the helper function defined in the same script (input: stabilizer tableau representation, output: entanglement entropy value) (see Ref 3, it would be better to try hard to accelerate this function)
  5. Validate the correctness by directly computing entanglement from tc (mid-circuit measurement results might require to be averaged)

Hi @refraction-ray I got the stabilizer example to work now I will be covering the points in the PR Issue

@refraction-ray I got the stabilizer example to work with mid circuit measurements

AbdullahKazi500 commented 1 month ago

@refraction-ray is their a way to plot in stim

@refraction-ray I am getting stuck here --------------- AttributeError: 'stim._stim_sse2.TableauSimulator' object has no attribute 'simulate' probably checking

AbdullahKazi500 commented 1 month ago

@refraction-ray this issue is done now just stuck at the 4 point it is really hard to get that function to work

AbdullahKazi500 commented 1 month ago

@refraction-ray finally the code works after modification I will make a PR

AbdullahKazi500 commented 1 month ago

stim

AbdullahKazi500 commented 1 month ago

@refraction-ray can I get some feedback

refraction-ray commented 1 month ago

@AbdullahKazi500 ， you can open an PR so that I can review the script if you have already got the example work and the result entanglement is checked to be correct

Hi, I would also like to work on this issue.
