Magic Resource Can Enhance the Quantum Capacity of Channels

2024 · arXiv (Cornell University)

We investigate the role of magic resource in the quantum capacity of channels. We consider the quantum channel of the recently proposed discrete beam splitter with the fixed environmental state. We find that if the …

A Universal Circuit Set Using the $S_3$ Quantum Double

2024 · arXiv (Cornell University)

One potential route toward fault-tolerant universal quantum computation is to use non-Abelian topological codes. In this work, we investigate how to achieve this goal with the quantum double model $\mathcal{D}(S_3)$ -- a specific non-Abelian topological …
