Holographic Mutual Information is Monogamous
Speaker(s): Patrick Hayden
Abstract: I'll describe a special information-theoretic property of quantum field theories with holographic duals: the mutual informations among arbitrary disjoint spatial regions A,B,C obey the inequality I(A:BC) >= I(A:B)+I(A:C), provided entanglement entropies are given by the Ryu-Takayanagi form... read more

On the fast scrambling conjecture
Speaker(s): Patrick Hayden
Abstract: Motivated by the consistency of black hole complementarity, Sekino and Susskind have conjectured that no physical system can "scramble" its internal degrees of freedom in time faster than (1/T) log S, where T is temperature and S the system's entropy. By considering a number of toy... read more

From low-distortion embeddings to information locking
Speaker(s): Patrick Hayden
Abstract: I'll describe a connection between uncertainty relations, information locking and low-distortion embeddings of L2 into L1. Exploiting this connection leads to the first explicit construction of entropic uncertainty relations for a number of measurements that is polylogarithmic in the dimension d whi... read more

From Tornadoes to Black Holes: How to Survive an Information Catastrophe
Speaker(s): Patrick Hayden
Abstract: Black holes are regions of space with gravity so strong that nothing can escape from them, not even light. This isn't science fiction - there's even a gigantic black hole at the center of our galaxy. It's hard to imagine a more effective way to irrevocably erase and destroy a computer's hard drive t... read more

Black holes as mirrors
Speaker(s): Patrick Hayden
Abstract: I'll discuss information retrieval from evaporating black holes, assuming that the internal dynamics of a black hole is unitary and rapidly mixing, and assuming that the retriever has unlimited control over the emitted Hawking radiation. If the evaporation of the black hole has already proceeded pas... read more

The power of forgetting
Speaker(s): Patrick Hayden
Abstract: Thermodynamics places surprisingly few fundamental constraints on information processing. In fact, most people would argue that it imposes only one, known as Landauer's Principle: a process erasing one bit of information must release an amount kT ln 2 of heat. It is this simple observation that ... read more
