Quantum Channel Simulation in Fidelity is no more difficult than State Splitting
Michael X. Cao, Rahul Jain, Marco Tomamichel
Characterizing the minimal communication needed for the quantum channel simulation is a fundamental task in the quantum information theory. In this paper, we show that, in fidelity…
Channel Simulation: Finite Blocklengths and Broadcast Channels
Michael X. Cao, Navneeth Ramakrishnan, Mario Berta +1
We study channel simulation under common randomness assistance in the finite-blocklength regime and identify the smooth channel max-information as a linear program one-shot convers…
Comments on "Channel Coding Rate in the Finite Blocklength Regime": On the Quadratic Decaying Property of the Information Rate Function
Michael X. Cao, Marco Tomamichel
The quadratic decaying property of the information rate function states that given a fixed conditional distribution , the mutual information between the…
Factor Graphs for Quantum Information Processing
Michael X. Cao
[...] In this thesis, we are interested in generalizing factor graphs and the relevant methods toward describing quantum systems. Two generalizations of classical graphical models…
Bounding and Estimating the Classical Information Rate of Quantum Channels with Memory
Michael X. Cao, Pascal O. Vontobel
We consider the scenario of classical communication over a finite-dimensional quantum channel with memory using a separable-state input ensemble and local output measurements. We p…
Double-Edge Factor Graphs: Definition, Properties, and Examples
Michael X. Cao, Pascal O. Vontobel
Some of the most interesting quantities associated with a factor graph are its marginals and its partition sum. For factor graphs \emph{without cycles} and moderate message update…
Estimating the Information Rate of a Channel with Classical Input and Output and a Quantum State (Extended Version)
Michael X. Cao, Pascal O. Vontobel
We consider the problem of transmitting classical information over a time-invariant channel with memory. A popular class of time-invariant channels with memory are finite-state-mac…
