Broadband spectroscopy of quantum noise
Yuanlong Wang, Gerardo A. Paz-Silva
Characterizing noise is key to the optimal control of the quantum system it affects. Using a single-qubit probe and appropriate sequences of and non- pulses, we show how one…

Two-stage solution for ancilla-assisted quantum process tomography: error analysis and optimal design
Shuixin Xiao, Yuanlong Wang, Daoyi Dong +1
Quantum process tomography (QPT) is a fundamental task to characterize the dynamics of quantum systems. In contrast to standard QPT, ancilla-assisted process tomography (AAPT) fram…
