Tutte Seminar - Ashwin Nayak

Title: Online Learning of Quantum States

Speaker: Ashwin Nayak
Affiliation: University of Waterloo
Room: MC 5501

Abstract:

Suppose we have many copies of an unknown n-qubit state rho. We measure some copies of rho using a known two-outcome measurement E_1, then other copies using a measurement E_2, and so on.
