Non-contextual correlations in probabilistic models
Speaker(s): Andreas Winter
Abstract: Non-contextuality is presented as an abstraction and at the same time generalisation of locality. Rather than in correlations, the underlying physical model leaves its signature in collections of expectation values, which are contrained by inequalities much like Bell's or Tsirelson's inequalities.

Approximate vs complete quantum information erasure: constructions and applications
Speaker(s): Andreas Winter
Abstract: It is a fundamental, if elementary, observation that to obliterate the quantum information in n qubits by random unitaries, an amount of randomness of at least 2n bits is required. If the randomisation condition is relaxed to perform only approximately, we obtain two answers, depending on the norm u... read more
