Scalable Fluxonium Quantum Processors via Tunable-Coupler Architecture
Ze Zhan, Zishuo Li, Fei Wang +24
Superconducting quantum processors have largely converged on transmon-based architectures, while alternative qubit modalities with intrinsic error protection have lacked a demonstr…
Benchmarking TCL4: Assessing the Usability and Reliability of Fourth-Order Approximations
Jiahao Chen, Elyana Crowder, Lian Xiang +1
The non-Markovian dynamics of an open quantum system can be rigorously derived using the Feynman-Vernon influence functional approach. Although this formalism is exact, practical n…
Creating and controlling global Greenberger-Horne-Zeilinger entanglement on quantum processors
Zehang Bao, Shibo Xu, Zixuan Song +30
Greenberger-Horne-Zeilinger (GHZ) states, also known as two-component Schrödinger cats, play vital roles in the foundation of quantum physics and, more attractively, in future qua…
Quantum highway: Observation of minimal and maximal speed limits for few and many-body states
Zitian Zhu, Lei Gao, Zehang Bao +30
Tracking the time evolution of a quantum state allows one to verify the thermalization rate or the propagation speed of correlations in generic quantum systems. Inspired by the ene…
