Abstract
Quantum measurement of amplitude fluctuation is performed by the injection of 2.5-dB amplitude-squeezed light produced by a quantum-well laser into th e dark port of a beam splitter as the meter wave, It is shown that the meas urements satisfy the criteria of quantum nondemolition measurement. The mea sured transfer coefficient and the quantum-state preparation ability are 1. 07 and 0.8, respectively. (C) 2001 Optical Society of America.
