    "abstract": "I utilize the Caves-Milburn model for continuous position measurements to\nformulate a broadband version of the Standard Quantum Limit (SQL) for\nmonitoring the position of a free mass, and illustrate the use of Kalman\nfiltering to recover the SQL for estimating a weak classical force that acts on\na quantum-mechanical test particle under continuous observation. These\nderivations are intended to clarify the interpretation of SQL\u0027s in the context\nof continuous quantum measurement.",
