Heralded Leakage Detection with Preserved Computational-State Coherence in a Fixed-Frequency Transmon
Takeaki Miyamura, Zhiling Wang, Peter A. Spring +5
Leakage out of the computational subspace is a major error mechanism in superconducting quantum processors. Detecting leakage without disturbing the encoded quantum information can…
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…
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…
Realisation of a Protected Cat-Qutrit Manifold via Engineered Quantum Tunnelling
Sangil Kwon, Daisuke Hoshi, Toshiaki Nagase +8
Engineering quantum tunnelling in phase space has emerged as a viable method for creating a protected logical qubit manifold with biased-noise properties. A promising approach is t…
Probing instantaneous quantum circuit refrigeration in the quantum regime
Shuji Nakamura, Teruaki Yoshioka, Sergei Lemziakov +8
Recent advancements in circuit quantum electrodynamics have enabled precise manipulation and detection of the single energy quantum in quantum systems. A quantum circuit refrigerat…
