Dynamically suppressing cavity dephasing induced by frequency fluctuations of a coupled nonlinear mode
Yunwei Lu, Xinyuan You, Ziwen Huang +3
High-coherence superconducting cavities offer a promising platform for quantum information, with long coherence times and negligible intrinsic dephasing. However, cavity control ge…
Crosstalk-Robust Quantum Control in Multimode Bosonic Systems
Xinyuan You, Yunwei Lu, Taeyoon Kim +10
High-coherence superconducting cavities offer a hardware-efficient platform for quantum information processing. To achieve universal operations of these bosonic modes, the requisit…
Optimal control of large quantum systems: assessing memory and runtime performance of GRAPE
Yunwei Lu, Sandeep Joshi, Vinh San Dinh +1
Gradient Ascent Pulse Engineering (GRAPE) is a popular technique in quantum optimal control, and can be combined with automatic differentiation (AD) to facilitate on-the-fly evalua…
Completely Positive Map for Noisy Driven Quantum Systems Derived by Keldysh Expansion
Ziwen Huang, Yunwei Lu, Anna Grassellino +3
Accurate modeling of decoherence errors in quantum processors is crucial for analyzing and improving gate fidelities. To increase the accuracy beyond that of the Lindblad dynamical…
