Unified Flux Control Architecture for Fluxonium Qubits
Xianchuang Pan, Jiahui Wang, Tao Zhou +14
Control architectures that reduce hardware overhead while maintaining high-fidelity operations are essential for the continued scaling of superconducting quantum processors. Here w…
Dissipative Time Quasicrystals from Multilevel Interference
Kang Shen, Xiangming Hu, Fei Wang
Boundary time crystals exhibit spontaneous breaking of continuous time-translation symmetry through persistent periodic oscillations in driven-dissipative many-body systems. Here,…
Identify and Quantify Various Dissipation Mechanisms of Josephson Junction in Superconducting Circuits
Hao Deng, Huijuan Zhan, Lijuan Hu +12
Pinpointing the dissipation mechanisms and evaluating their impacts to the performance of Josephson junction (JJ) are crucial for its application in superconducting circuits. In th…
High coherence fluxonium manufactured with a wafer-scale uniformity process
Fei Wang, Kannan Lu, Huijuan Zhan +32
Fluxonium qubits are recognized for their high coherence times and high operation fidelities, attributed to their unique design incorporating a superinductor, which is typically im…
