Measurement process in relativistic quantum theory

Yakir Aharonov, David Z. Albert, Lev Vaidman

Research output: Contribution to journalArticlepeer-review


An instantaneous nondemolition measurement technique for composite quantum-mechanical systems (those which consist of several separate subsystems) is described, and that technique is applied to the design of verification experiments for some nonlocal variables and states. Relativistic restrictions on the measurability of nonlocal properties are derived, and other, less familiar, varieties of measurement are discussed.
