Boundary States and Entanglement Spectrum from Strong Subadditivity
Speaker(s): Fernando Brandao
Abstract: In this talk I will consider quantum states satisfying an area law for entanglement (e.g. as found in quantum field theory or in condensed matter systems at sufficiently low temperature). I will show that both the boundary state and the entanglement spectrum admit a local description whenever there ... read more

Quantum Data Hiding: Challenges and Opportunities
Speaker(s): Fernando Brandao
Abstract: Correlations in quantum states are sometimes inaccessible if only restricted types of quantum measurements can be performed, an effect known as quantum data hiding. For example highly entangled states shared by two parties might appear uncorrelated if the parties can only measure locally their share... read more

Hasting's counterexamples on the minimum output entropy additivity conjecture by measure concentration
Speaker(s): Fernando Brandao
Abstract: In 2008 Hastings reported a randomized construction of channels violating the minimum output entropy additivity conjecture. In this talk we revisit his argument, presenting a simplified proof. In particular, we do not resort to the exact probability distribution of the Schmidt coefficients of a rand... read more
