A prototype of quantum von Neumann architecture
D. -S. Wang
A modern computer system, based on the von Neumann architecture, is a complicated system with several interactive modular parts. Quantum computing, as the most generic usage of qua…

Symmetry-protected topological phases with uniform computational power in one dimension
Robert Raussendorf, Dongsheng Wang, Abhishodh Prakash +2
We investigate the usefulness of ground states of quantum spin chains with symmetry-protected topological order (SPTO) for measurement-based quantum computation. We show that, in s…

Complete positivity and contextuality of quantum dynamics
Song Cheng, Dongsheng Wang
Positivity or the stronger notion of complete positivity, and contextuality are central properties of quantum dynamics. In this work, we demonstrate that a physical unitary-univers…
