Abstract

Author(s): S. Hernández-Gómez, F. Poggiali, P. Cappellaro, and N. Fabbri Knowing a quantum system's environment is critical for its practical use as a quantum device. Qubit sensors can reconstruct the noise spectral density of a classical bath, provided long enough coherence time. Here, we present a protocol that can unravel the characteristics of a more complex environm... [Phys. Rev. B 98, 214307] Published Mon Dec 17, 2018
