    "abstract": "Quantum mechanics sets severe limits on the sensitivity and required\ncirculating energy in traditional free-mass gravitational-wave antennas. One\npossible way to avoid these restrictions is the use of intracavity QND\nmeasurements. We analyze a new QND observable, which possesses a number of\nfeatures that make it a promising candidate for such measurements and propose a\npractical scheme for the realization of this measurement. In combination with\nan advanced coordinate meter, this scheme makes it possible to lower\nsubstantially the requirements on the circulating power.",
