Quantum Computing

My IBM Quantum Challenge’21 Experience- Part 2

Solving the third and the fourth exercises of the IQC’21.

3. Quantum Error Correction:

Combination of the initial circuit and syndrome measurement circuit
For error x0:
Output was 0010 for 1024 shots.

For error x1:
Output was 0100 for 1024 shots.

For error z0:
Output was 0001 for 1024 shots.

For error z1:
Output was 1000 for 1024 shots.
