John Calsamiglia: Local vs Collective measurements in statistical inference
John Calsamiglia, Universitat Autònoma de Barcelona
Abstract
I will present three problems in quantum statistical inference that all stem from the difference between local and collective measurements on multipartite states.
The first one is that of hiding a secret direction in a multipartite state with the promise that the parties cannot learn the direction if they perform local operations and classical communication, but can accurately retrieve it if they perform collective measurements.
