Minimal Counterexamples of the MacWilliams Extension Theorem for Stabilizer Codes
Ali Assem Mahmoud
The MacWilliams extension theorem fails for module alphabets with non-cyclic socle, and the label alphabet of qudit stabilizer codes, $\F_{q^2}$ over $\F_q$, is such an alphabet. Q…

Benchmarking Quantum Instruments
Darian McLaren, Matthew A. Graydon, Ali Assem Mahmoud +1
Quantum measurements with feed-forward are crucial components of fault-tolerant quantum computers. We show how the error rate of such a measurement can be directly estimated by fit…
