Foundations of QM Seminar (Feb. 3) (DIFFERENT ROOM: 028)

[Dardashti, Radin]

Dear all,

our "Foundations of Quantum Mechanics" seminar continues Monday with 
Michael Cuffaro "On the Significance of the Gottesman-Knill Theorem".

Abstract:
According to the Gottesman-Knill theorem, quantum algorithms utilising 
operations chosen from a particular restricted set are efficiently 
simulable classically. Since some of these algorithms involve entangled 
states, it is commonly concluded that entanglement is not sufficient to 
enable quantum computers to outperform classical computers. It is argued 
in this paper, however, that what the Gottesman-Knill theorem shows us 
is only that if we limit ourselves to the Gottesman-Knill operations, we 
will not have used the entanglement with which we have been provided to 
its full potential, for all of the Gottesman-Knill operations are such 
that their associated statistics (even when they involve entangled 
states) are reproducible in a local hidden variables theory. It is 
further argued that considering the Gottesman- Knill theorem is 
illuminating, not only for our understanding of quantum computation, but 
also for our understanding of what we take to be a plausible local 
hidden variables theory, as well as for our understanding of the 
relationship between all-or-nothing inequalities such as GHZ, and 
statistical inequalities such as CHSH.
