Comment on "Probing Noise in Flux Qubits via Macroscopic Resonant Tunneling" (arXiv:0712.0838)
arXiv:0903.3575
Abstract
Expert attention is attracted to the obvious contradiction of the assumption on macroscopic quantum tunnelling and on superposition of two macroscopically distinct quantum states of superconducting loop, considered as flux qubit, with the law of angular momentum conservation and the universally recognized quantum formalism.
