摘要：
We present temperature measurements of the back action of a low noise DC SQUID on a strongly coupled electrical resonator operating at 1480 Hz with quality factors up to Q = 1.2 x 10(6). The characteristics of the voltage noise of the SQUID current amplifier are discussed and compared with the predictions. (C) 2000 Elsevier Science B.V. All rights reserved.
