Dear all,
Will Matthews will be visiting us next week (2.-4th Feb) and will give a talk on Wednesday.
Time and Location: Wednesday, 2 February 2011, noon, HIT K 51 Speaker: William Matthews (IQC Waterloo) Title: Entanglement can increase asymptotic rates of zero-error classical communication over classical channels Abstract: It is known that the number of different classical messages which can be communicated with a single use of a classical channel with zero probability of decoding error can sometimes be increased by using entanglement shared between sender and receiver. It has been an open question to determine whether entanglement can ever increase the zero-error communication rates achievable in the limit of many channel uses. In this paper we show, by explicit examples, that entanglement can indeed increase asymptotic zero-error capacity, even to the extent that it is equal to the normal capacity of the channel. Interestingly, our examples are based on the exceptional simple root systems E7 and E8. See http://arxiv.org/abs/1009.1195
See you, Matthias.
