Query: SQUIDs based set-up for probing current noise and correlations in
  three-terminal devices   We have implemented a new experimental set-up for precise measurements of
current fluctuations in three-terminal devices. The system operates at very low
temperatures (30 mK) and is equipped with three SQUIDs as low noise current
amplifiers. A SQUID input coil is connected to each terminal of a sample
allowing the acquisition of time-dependent current everywhere in the circuit.
From these traces, we can measure the current mean value, the noise and
cross-correlations between different branches of a device. In this paper we
present calibration results of noise and cross-correlations obtained using low
impedance macroscopic resistors. From these results we can extract the noise
level of the set-up and show that there are no intrinsic correlations due to
the measurement scheme. We also studied noise and correlations as a function of
a DC current and estimated the electronic temperature of various macroscopic
resistors.
