Secret sharing and related protocols play  an important role in cryptography and have a rich mathematical  structure. It is an important primitive in many network tasks, for  example secure multiparty computation. In recent years various quantum  versions of secret sharing and related variants have arrisen, with deep  connections to several areas of information processing including error  correction and the MDS conjecture. We will review secret sharing, data  hiding and related other protocols to see how quantum mechanics can be  used to shuffle information around and protect it in a multiparty  setting.<\/em><\/p>\n<p>The<strong> 14th QUISCO meeting<\/strong> was at Edinburgh at the Informatics Forum on the 27th July 2011. <a href=\"..\/..\/meeting110727.html\">Preliminary details<\/a>.<\/p>\n<p>The<a href=\"http:\/\/www.carnegie-trust.org\/\"> Carnegie Trust<\/a> has been a strong supporter of QUISCO and its visitor programme.

This is based upon two main ways in which quantum  systems exhibit non-classicality: the apparent (exponential) complexity  of simulating quantum systems classically, and non-local behaviour due  to entanglement. Which leads to another fundamental question in physics:  &#8220;If computing predictions for Quantum Mechanics requires exponential  resources, is Quantum Mechanics a falsifiable theory?&#8221; I will briefly  overview how a computational thinking has contributed towards these  directions highlighting many remaining exciting open questions of the  field. <\/em><\/p>\n<p><strong>Talk by Dr Ernesto Galvao<\/strong> (IF-UFF, Rio de Janeiro)<br \/>\nWednesdays 13 Jan 2010 at 14:00 in room 4.31 of the Informatics Forum<br \/>\n<em><strong> Abstract:<\/strong> Physical experiments generate tables of  probabilities describing relative frequencies of outcomes. Harrigan et  al. [1] proposed a formalism to create simple models that explain any  such data set in terms of positive, normalized probability distributions  over a certain number of variables (called ontic states), using  indicator functions to describe measurements. I will review this  formalism with some simple examples, and discuss strategies that  decrease the number of ontic states to obtain models that are as simple  as possible. As an application, I will describe models for  informationally complete measurements on the simplest quantum systems  having just two and three distinguishable states [2]. These models were  obtained using a high-dimensional computational geometry algorithm [3].<\/em><br \/>\n<strong>References:<\/strong><br \/>\n[1] N. Harrigan, T. Rudolph, S.
