ZZ-Free bSWAP Gates under Strong Driving in Far-Detuned Fixed-Frequency Transmons
Akinori Machino, Kazuhisa Ogawa, Yuto Ikegai +9
Far-detuned frequency allocations in fixed-frequency superconducting processors mitigate spectral crowding but constrain cross-resonance interactions at practical drive amplitudes.…
QuBE/Qubex: an integrated hardware-software system for superconducting qubit experiments with broadband control
Akinori Machino, Kazuhisa Ogawa, Takefumi Miyoshi +21
Achieving high-fidelity operation in large-scale superconducting qubit systems requires not only control hardware with broad frequency coverage, low crosstalk, and tight synchroniz…
A Practical Open-Source Software Stack for a Cloud-Based Quantum Computing System
Norihiro Kakuko, Shun Gokita, Naoyuki Masumoto +10
Since the late 2010s, quantum computers have become commercially available, and the number of services that users can run remotely via cloud servers is increasing. In Japan, severa…
Auxiliary-field quantum Monte Carlo method with quantum selected configuration interaction
Yuichiro Yoshida, Luca Erhart, Takuma Murokoshi +5
We propose using the wave function generated by the quantum selected configuration interaction (QSCI) method as the trial wave function in phaseless auxiliary-field quantum Monte C…
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…
