On the separation of correlation-assisted sum capacities of multiple access channels
Akshay Seshadri, Felix Leditzky, Vikesh Siddhu +1
The capacity of a channel characterizes the maximum rate at which information can be transmitted through the channel asymptotically faithfully. For a channel with multiple senders…
The platypus of the quantum channel zoo
Felix Leditzky, Debbie Leung, Vikesh Siddhu +2
Understanding quantum channels and the strange behavior of their capacities is a key objective of quantum information theory. Here we study a remarkably simple, low-dimensional, si…
Generic nonadditivity of quantum capacity in simple channels
Felix Leditzky, Debbie Leung, Vikesh Siddhu +2
Determining capacities of quantum channels is a fundamental question in quantum information theory. Despite having rigorous coding theorems quantifying the flow of information acro…
