Characterization of coherent power of concatenation of quantum channels

2015 · arXiv (Cornell University)

Quantum coherence, existing in quantum states, is a very important resource for design and implementation of quantum technologies. Quantum channels that can generate coherence is also an interesting topic and less known results about it. …

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 …
