Quantum mechanical 'Backward in Time'? Comments, Answers, and the Causal Indistinguishability Condition
arXiv:quant-ph/9805021
Abstract
We discuss a number of comments on quant-ph/9801061, and propose to introduce the concept of 'Causal Indistinguishability'. The incompatibility between Quantum Mechanics and Nonlocal Causality appears to be unavoidable: upholding of Quantum Mechanics by experiment would mean to live with influences backward in time, just as we are now living with such faster than light.
