Researchers have demonstrated that the addition of an optimal level of such noise can sometimes make it easier to detect faint, information-carrying signals in electronic circuits and superconducting quantum interference devices (SN: 2/23/91, p.
In this research paper, the scientists show that a magnetic field-pulsed microwave transmission line containing an array of superconducting quantum interference devices, or SQUIDs, not only reproduces physics analogous to that of a radiating black hole, but does so in a system where the high energy and quantum mechanical properties are well understood and can be directly controlled in the laboratory.
