CAUSALITY, MEMORY ERASING AND DELAYED CHOICE EXPERIMENTS
arXiv:quant-ph/9501006 · doi:10.1103/PhysRevA.52.4984
Abstract
Comment on [R.L. Ingraham, Phys. Rev. A 50, 4502 (1994)]. Ingraham suggested ``a delayed-choice experiment with partial, controllable memory erasing''. It is shown that he cannot be right since his predictions contradict relativistic causality. A subtle quantum effect which was overlooked by Ingraham is explained.
