On the two-copy distillability of Werner states and a new partial trace inequality
Thomas C. Fraser, Felix Huber, Balázs Pozsgay +1
Problem 5 in {\it Five Open Problems in Quantum Information Theory} [PRX Quantum 3, 010101 (2022)], asks whether the two-ququart Werner state is two-copy dis…
Complete entanglement detection using polynomial invariants
Thomas C. Fraser, Vjosa Blakaj, Roberto Rubboli +2
Existing methods for deciding whether a bipartite quantum state is separable or entangled typically fall into one of two categories: they are either complete but require access to…
On quantum functionals for higher-order tensors
Alonso Botero, Matthias Christandl, Thomas C. Fraser +2
Upper and lower quantum functionals, introduced by Christandl, Vrana and Zuiddam (STOC 2018, J. Amer. Math. Soc. 2023), are families of monotone functions of tensors indexed by a w…
The tetrahedral Horn problem and asymptotics of U(n) 6j symbols
Anton Alekseev, Matthias Christandl, Thomas C. Fraser
Horn's problem is concerned with characterizing the eigenvalues of Hermitian matrices satisfying the constraint and forming the edges of a triangle in t…
An estimation theoretic approach to quantum realizability problems
Thomas C. Fraser
This thesis seeks to develop a general method for solving so-called quantum realizability problems, which are questions of the following form: under which conditions does there exi…
A sufficient family of necessary inequalities for the compatibility of quantum marginals
Thomas C. Fraser
The quantum marginal problem is concerned with characterizing which collections of quantum states on different subsystems are compatible in the sense that they are the marginals of…
Understanding the interplay of entanglement and nonlocality: motivating and developing a new branch of entanglement theory
David Schmid, Thomas C. Fraser, Ravi Kunjwal +3
A standard approach to quantifying resources is to determine which operations on the resources are freely available, and to deduce the partial order over resources that is induced…
A Combinatorial Solution to Causal Compatibility
Thomas C. Fraser
Within the field of causal inference, it is desirable to learn the structure of causal relationships holding between a system of variables from the correlations that these variable…
Machine Learning Peeling and Loss Modelling of Time-Domain Reflectometry
J. R. Rinehart, J. H. Béjanin, T. C. Fraser +1
A fundamental pursuit of microwave metrology is the determination of the characteristic impedance profile of microwave systems. Among other methods, this can be practically achieve…
Causal Compatibility Inequalities Admitting Quantum Violations in the Triangle Structure
Thomas C. Fraser, Elie Wolfe
It has long been recognized that certain quantum correlations are incompatible with particular assumption about classical causal structure. Given a causal structure of unknown clas…
