All-microwave manipulation of superconducting qubits with a fixed-frequency transmon coupler
Shotaro Shirai, Yuta Okubo, Kohei Matsuura +3
All-microwave control of fixed-frequency superconducting quantum computing circuits is advantageous for minimizing the noise channels and wiring costs. Here we introduce a swap int…
Efficient low-energy single-electron detection using a large-area superconducting microstrip
Masato Shigefuji, Alto Osada, Masahiro Yabuno +3
Superconducting strip single-photon detectors (SSPDs) are excellent tools not only for single-photon detection but also for single-particle detection owing to their high detection…
Feasibility study on ground-state cooling and single-phonon readout of trapped electrons using hybrid quantum systems
Alto Osada, Kento Taniguchi, Masato Shigefuji +1
Qubits of long coherence time and fast quantum operations are long-sought objectives towards the realization of high-fidelity quantum operations and their applications to the quant…
Deterministic loading of a single strontium ion into a surface electrode trap using pulsed laser ablation
Alto Osada, Atsushi Noguchi
Trapped-ion quantum technologies have been developed for decades toward applications such as precision measurement, quantum communication and quantum computation. Coherent manipula…
Superconducting Acousto-optic Phase Modulator
Ayato Okada, Rekishu Yamazaki, Maria Fuwa +9
We report the development of a superconducting acousto-optic phase modulator fabricated on a lithium niobate substrate. A titanium-diffused optical waveguide is placed in a surface…
Dissipation-based Quantum Sensing of Magnons with a Superconducting Qubit
Samuel Piotr Wolski, Dany Lachance-Quirion, Yutaka Tabuchi +4
Hybrid quantum devices expand the tools and techniques available for quantum sensing in various fields. Here, we experimentally demonstrate quantum sensing of the steady-state magn…
