In connection with the sensitivity demands on gravitational-wave detection experiments, questions regarding the impact of quantum-mechanical limits on the efforts to detect gravitational waves were considered. Thus, Braginsky and Vorontsov (1974) argued for a limit on the uncertainty Delta x of the second measurement of position of a free mass m after a time tau. The resulting equation is called the standard quantum limit (SQL) for monitoring the position of a free mass. Yuen (1983) has pointed out a flaw in the arguments presented by Braginsky and Vorontsov. The various aspects involved are examined, taking into account discussions of quantum measurements and considerations related to SQL. A repeated measurement scheme to monitor the free-mass position to an arbitrary accuracy is constructed, and the resulting formulas are presented.
