Hi all,
we'll hear from Zi-Wen Liu on Friday at 2pm in E41.1. Here's the title and
abstract:
Title: A theory of resource destruction
Abstract: Resource theory is a widely-applicable framework for analyzing
the physical resources required for given tasks, such as computation,
communication, and energy extraction. In this talk, we propose a general
scheme for studying and understanding resource theories based on
resource-destroying maps, which leave resource-free states unchanged but
erase the resource stored in all other states. In particular, we introduce
a group of simple conditions for the class of resource-free operations,
which plays a key role in the general framework of resource theories. Our
theory reveals fundamental connections among free states, free operations
and resource measures. We explicitly discuss our theory in the contexts of
coherence and discord to illustrate properties of resource destruction.
Best,
