  17. (Jack Sarfatti) writes:
  18. |OK boys and girls. I may have found an error in my "retraction proof" that
  19. |standard unitary reversible (forget dissipation) quantum mechanics does not
  20. |permit the quantum connection signal.
  21.  
  22. Ugh.
  23.  
  24. |Therefore, even though the "bare" inner product vanishes, i.e.,
  25. |
  26. |<1e+|1o-> = 0  (5)
  27. |
  28. |We cannot logically conclude that the "dressed" inner product (i.e., matrix
  29. |element of operator S(&)e^-i&|1&><1&| sandwiched between these orthogonal
  30. |states) also vanishes.
  31.  
  32. Call this operator S(&)e^-i&|1&><1&| of yours "U". If U is unitary,
  33. then <1e+|1o->=0 DOES logically imply that <1e+|U|1o->=0 also.
