We demonstrate a substantial gap between local and nonlocal strategies in a quantum state discrimination task under a non-destructiveness condition. The condition imposes additional constraints to conventional state discrimination that the initial state should be returned without disturbance. For a set of maximally entangled states, the success probability of the proposed task using local operations and classical communications is completely suppressed; it cannot beat random guessing. We also show that a local strategy that efficiently exploits pre-shared entanglement for this task can be essentially different from the conventional approaches. We construct a nondestructive and adaptive strategy to achieve perfect discrimination of maximally entangled states which has a strictly lower entanglement cost than the best-known method based on teleportation. Our approach can be generalized to multipartite scenarios, offering an application in entanglement certification of a quantum network.
Purpose: The purpose of this study is to provide data on the basis for architectural planning of floor plan type and spatial composition by analysing standard mental health centers in Seoul. Methods:Data were collected through literature research, field surveys, and expert interviews to 22 standard mental health centers in Seoul. Results: The results of this study could be summarized as follows;
Purpose: Economic and social pressures are driving Korea to reform its mental health services. However, it is not easy for the governments to find to the proper method for the mental health service network. This study is to find the mental health service network in Japan. Methods: The survey was conducted by researches and field studies. 1) Researches for mental health service network and facilities. 2) Field study is for Mental Health and Welfare Network in Tokyo. Results: The result of this study can be summarized into three points.The first one, Reform measures are beginning to promote the concept of "normalization" in japanese society.The second one, Facilities of Mental health and welfare system designed by level that can be providing places for people with mental problems. The third one, Facilities consist of barrier-free environment for people with mental problems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
