Phys. Rev. D 29, 228–234 (1984)Is the usual notion of time evolution adequate for quantum-mechanical systems? II. Relativistic considerationsReceived 17 March 1983; published in the issue dated 15 January 1984 The measurement of nonlocal properties of relativistic quantum-mechanical systems, the compatibility (or lack of it) of two or more such measurements, and various other of their characteristics are considered; and with these notions in hand an old problem (which is to produce a covariant description of the state reduction associated with the measuring process) is attacked, and succumbs. The solution requires us to depart (not as we did in part I of the present work, but in an entirely different direction) from the usual picture of the time evolution of quantum states. © 1984 The American Physical Society URL:
