Optimal Measurements of Magnetic Flux in Superconducting Circuits and Macroscopic Quantum Mechanics
arXiv:quant-ph/9502001 · doi:10.1016/0375-9601(94)01020-U
Abstract
A model of repeated quantum measurements of magnetic flux in superconducting circuits manifesting tunneling is discussed. The perturbation due to the previous measurements of magnetic flux is always present unless quantum nondemolition measurements are performed. By replacing the classical notion of noninvasivity with this condition, temporal Bell-like inequalities allows one to test the observability at the macroscopic level of the conflict between realism and quantum theory.
