Influence-free states on compound quantum systems
Howard Barnum, Christopher A. Fuchs, Joseph M. Renes +1
Let Alice and Bob be able to make local quantum measurements and communicate classically. The set of mathematically consistent joint probability assignments (``states'') for such m…
On the Quantumness of a Hilbert Space
Christopher A. Fuchs
We derive an exact expression for the quantumness of a Hilbert space (defined in quant-ph/0302092), and show that in composite Hilbert spaces the signal states must contain at leas…
Gleason-Type Derivations of the Quantum Probability Rule for Generalized Measurements
Carlton M. Caves, Christopher A. Fuchs, Kiran Manne +1
We prove a Gleason-type theorem for the quantum probability rule using frame functions defined on positive-operator-valued measures (POVMs), as opposed to the restricted class of o…
The Quantumness of a Set of Quantum States
Christopher A. Fuchs, Masahide Sasaki
This article is an introduction to quant-ph/0302092. We propose to quantify how "quantum" a set of quantum states is. The quantumness of a set is the worst-case difficulty of trans…
Squeezing Quantum Information through a Classical Channel: Measuring the "Quantumness" of a Set of Quantum States
Christopher A. Fuchs, Masahide Sasaki
In this paper we propose a general method to quantify how "quantum" a set of quantum states is. The idea is to gauge the quantumness of the set by the worst-case difficulty of tran…
Quantum Mechanics as Quantum Information (and only a little more)
Christopher A. Fuchs
In this paper, I try once again to cause some good-natured trouble. The issue remains, when will we ever stop burdening the taxpayer with conferences devoted to the quantum foundat…
