아래와 같이 콜로퀴움을 개최하오니 많이 참석해 주시기 바랍니다. 4시 20분부터 제1과학관 31214 e+강의실 앞에서 다과를 준비하오니 많은 참석 부탁드립니다 아 래 제목: "Einstein was wrong?"--Two-proton spin- correlation measurement for EPR paradox. 연사: 사카이 히데유키 교수(RIKEN, 성균관대학교) 일시: 2010년 10월 8(금) 오후4:30 장소: e+첨단강의실 (31214호실) 초록: We have carried out the spin-correlation measurement of two protons in a spin singlet state aiming to test the EPR paradox presented by Einstein, Podolsky and Rosen in 1935. The EPR proposed a thought experiment in which they showed according to quantum mechanics that the result of a measurement of an entangled quantum system performed on earth, for example, can instantaneously influence the result of a measurement performed on the far distant Galaxy regardless of the distance. This of course contradicts with the theory of special relativity by Einstein, no information can be transmitted faster than the speed of light. Therefore EPR argued that quantum mechanics must be incomplete. In 1964, Bell found an extremely important inequality which is the embodiment of the EPR arguments. The prediction of the spin-correlation by the Bell's inequality is different from that by the quantum mechanics so that we can test experimentally which assertion is right by the measurement. After a short introduction of the EPR paradox, I try to explain how we realized almost pure spin singlet state of two protons experimentally and how we measured the spin polarizations of two protons followed by the result.
