Ryo Okamoto: Special Seminar - Demonstration of Adaptive Quantum Estimation with Photons

Abstract

Quantum theory is inherently statistical. This entails repetition of experiments over a number of identically prepared quantum objects, if one wants to know the "true state" or the "true value" of the parameter that specifies the quantum state. In applications, one needs to design the estimation procedure in such a way that the estimated value of the parameter should be close to the true value (consistency), and that the uncertainty of the estimated value should be as small as possible (efficiency).

Francesco Buscemi (Nagoya University): Q+ Hangout

Francesco Buscemi (Nagoya University), Institute for Quantum Computing (IQC)

Abstract

Title: - All entangled quantum states are nonlocal: equivalence between locality and separability in quantum theory

In this talk I will show how, by slightly modifying the rules of
nonlocal games, one can prove that all entangled states violate local
realism.
