Fundamental limits for thermodynamic control with quantum feedback
Kaiyuan Ji, Gilad Gour, Mark M. Wilde
The study of feedback control inspired by Maxwell's demon is central to the understanding of the relationship between thermodynamics and information. In this paper, we establish fu…
Retrocausal capacity of a quantum channel: Communicating through noisy closed timelike curves
Kaiyuan Ji, Seth Lloyd, Mark M. Wilde
We study the capacity of a quantum channel for retrocausal communication, where messages are transmitted backward in time, from a sender in the future to a receiver in the past, th…
Barycentric bounds on the error exponents of quantum hypothesis exclusion
Kaiyuan Ji, Hemant K. Mishra, Milán Mosonyi +1
Quantum state exclusion is an operational task with application to ontological interpretations of quantum states. In such a task, one is given a system whose state is randomly sele…
Beyond Hoeffding and Chernoff: Trading conclusiveness for advantages in quantum hypothesis testing
Kaiyuan Ji, Bartosz Regula
The ultimate limits of quantum state discrimination are often thought to be captured by asymptotic bounds that restrict the achievable error probabilities, notably the quantum Cher…
Converse bounds for quantum hypothesis exclusion: A divergence-radius approach
Kaiyuan Ji, Hemant K. Mishra, Milán Mosonyi +1
Hypothesis exclusion is an information-theoretic task in which an experimenter aims at ruling out a false hypothesis from a finite set of known candidates, and an error occurs if a…
Entropic and operational characterizations of dynamic quantum resources
Kaiyuan Ji, Eric Chitambar
We offer new methods for characterizing general closed and convex quantum resource theories, including dynamic ones, based on entropic concepts and operational tasks. We propose a…
