Symmetric Squares of Graphs
Koenraad Audenaert, Chris Godsil, Gordon Royle +1
We consider symmetric powers of a graph. In particular, we show that the spectra of the symmetric square of strongly regular graphs with the same parameters are equal. We also prov…
There, and Back Again: Quantum Theory and Global Optimisation
Koenraad M. R. Audenaert
We consider a problem in quantum theory that can be formulated as an optimisation problem and present a global optimisation algorithm for solving it, the foundation of which relies…
Multiplicativity of Accessible Fidelity and Quantumness for Sets of Quantum States
K. M. R. Audenaert, C. A. Fuchs, C. King +1
Two measures of sensitivity to eavesdropping for alphabets of quantum states were recently introduced by Fuchs and Sasaki in quant-ph/0302092. These are the accessible fidelity and…
The asymptotic relative entropy of entanglement
K. Audenaert, J. Eisert, E. Jane +3
We present an analytical formula for the asymptotic relative entropy of entanglement for Werner states of arbitrary dimension. We then demonstrate its validity using methods from c…
Negativity and Concurrence of mixed 2X2 states
Koenraad Audenaert, Frank Verstraete, Tijl De Bie +1
We consider two measures of entanglement of mixed bipartite states of dimension 2X2: concurrence and negativity. We first prove the conjecture of Eisert and Plenio that concurrence…
