Query: Quantum speedmeter and laser interferometric gravitational-wave antennae   A new topology of laser interferometric gravitational-wave antenna is
considered. It is based on two schemes: {\em quantum speedmeter} and {\em
zero-area Sagnac interferometer} and allows to obtain sensitivity better than
the Standard Quantum Limit in wide band without any large-scale modifications
of the standard topology of the laser interferometric antennae.
