Autler-townes energy-level engineering for high-quality all-microwave qubit gate
Wan-Peng Gao, Xiao-Liang He, Zheng-Qi Niu +7
High-fidelity entangling gates are essential for realizing large-scale fault-tolerant superconducting quantum computing, yet existing approaches are limited: frequency-tuning techn…
Ultralow-power coherent qubit control using AQFP logic at millikelvin temperatures
Hiroto Mukai, Akiyoshi Tomonaga, Rui Wang +5
Qubit controllers are essential for scaling superconducting quantum processors, but implementing them at the 10 mK stage of a dilution refrigerator remains challenging due to strin…
Control the qubit-qubit coupling with double superconducting resonators
Hui Wang, Rui Wang, Daichi Sugiyama +5
We experimentally studied the switching off processes in the double-resonator coupler superconducting quantum circuit. In both frequency and time-domain, we observed the variation…

Entangling Schrödinger's cat states by bridging discrete- and continuous-variable encoding
Daisuke Hoshi, Toshiaki Nagase, Sangil Kwon +9
In quantum information processing, two primary research directions have emerged: one based on discrete variables (DV) and the other on the structure of quantum states in a continuo…
Fast generation of Schrödinger cat states in a Kerr-tunable superconducting resonator
X. L. He, Yong Lu, D. Q. Bao +7
Schrödinger cat states, quantum superpositions of macroscopically distinct classical states, are an important resource for quantum communication, quantum metrology and quantum comp…
Ultrastrong tunable coupler between superconducting LC resonators
Takafumi Miyanaga, Akiyoshi Tomonaga, Hikaru Ito +2
We investigate the ultrastrong tunable coupler for coupling of superconducting resonators. Obtained coupling constant exceeds 1 GHz, and the wide range tunability is achieved both…
