Apparently, John Bell, who had been interested in the Bohr-Einstein dialogue, always took the position of Albert Einstein on philosophical issues. He also felt that a completion of quantum mechanics using so-called "hidden variables" would be highly desired, as it would help to regain a realistic and objective picture of the world. That way, Bell hoped one would be able to arrive at a physics where "measurement" would not play such a central role as in the Copenhagen interpretation of quantum mechanics. Then, a most interesting sequence of events set in. In 1952, David Bohm had achieved something which had earlier been proclaimed impossible. It had been proved by John von Neumann that no hidden variable theory could agree with quantum mechanics. Bohm actually formulated such a theory, where each particle at any time has both a well-defined position and a well defined momentum. The conflict raised between von Neumann and Bohm was elegantly resolved by Bell, who showed that von Neumann‘s proof contained a physically unjustifiable assumption. So while John Bell had flung | 出版日期 | Book 2002 | 关键词 | Anomalies in quantum fields; Bell‘s inequalities; cryptography; information; mechanics; quantum cryptogra | 版次 | 1 | doi | https://doi.org/10.1007/978-3-662-05032-3 | isbn_softcover | 978-3-642-07664-0 | isbn_ebook | 978-3-662-05032-3 | copyright | Springer-Verlag Berlin Heidelberg 2002 |
