Quantum computation from dynamic automorphism codes
Margarita Davydova, Nathanan Tantivasadakarn, Shankar Balasubramanian +1
We propose a new model of quantum computation comprised of low-weight measurement sequences that simultaneously encode logical information, enable error correction, and apply logic…

Exponential speedups for quantum walks in random hierarchical graphs
Shankar Balasubramanian, Tongyang Li, Aram Harrow
There are few known exponential speedups for quantum algorithms and these tend to fall into even fewer families. One speedup that has mostly resisted generalization is the use of q…
