We show that this limit of precision for the local quantum states of a pair of N-level systems can be defined by an appropriate class of uncertainty relations. The violation of such local uncertainty relations may be used as an experimental test of entanglement generation.American Physical SocietyJournal Articleapplication/pdfhttp://hdl.handle.net/2115/5553https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5553/1/PRA68-3.pdf1050-2947Physical Review A680321032003-09-22enginfo:doi/10.1103/PhysRevA.68.032103Copyright © 2003 American Physical Societypublisher
