Entangling Power and Symmetries in the Quantum Rabi Model
Ian Low, Jens Koch, Sahel Ashhab
The quantum Rabi model is a standard effective Hamiltonian in studies of light-matter interaction, capturing the simplest nontrivial setting in which a qubit couples to a single ha…
Randomized benchmarking with non-Markovian noise and realistic finite-time gates
Antoine Brillant, Peter Groszkowski, Alireza Seif +2
We analyze the impact of non-Markovian classical noise on single-qubit randomized benchmarking experiments, in a manner that explicitly models the realization of each gate via real…
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…
Systematic Improvements in Transmon Qubit Coherence Enabled by Niobium Surface Encapsulation
Mustafa Bal, Akshay A. Murthy, Shaojiang Zhu +37
We present a novel transmon qubit fabrication technique that yields systematic improvements in T relaxation times. We fabricate devices using an encapsulation strategy that inv…
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…
Experimental verification of the treatment of time-dependent flux in circuit quantization
Jacob Bryon, D. K. Weiss, Xinyuan You +5
Recent theoretical work has highlighted that quantizing a superconducting circuit in the presence of time-dependent flux generally produces Hamiltonian terms proportional to…
