Fast readout and reset of a superconducting qubit coupled to a resonator with an intrinsic Purcell filter
Yoshiki Sunada, Shingo Kono, Jesper Ilves +4
Coupling a resonator to a superconducting qubit enables various operations on the qubit, including dispersive readout and unconditional reset. The speed of these operations is limi…
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…
Fast parametric two-qubit gates with suppressed residual interaction using a parity-violated superconducting qubit
Atsushi Noguchi, Alto Osada, Shumpei Masuda +7
We demonstrate fast two-qubit gates using a parity-violated superconducting qubit consisting of a capacitively-shunted asymmetric Josephson-junction loop under a finite magnetic fl…
Programmable directional emitter and receiver of itinerant microwave photons in a waveguide
Nicolas Gheeraert, Shingo Kono, Yasunobu Nakamura
We theoretically demonstrate dynamically selective bidirectional emission and absorption of a single itinerant microwave photon in a waveguide. The proposed device is an artificial…
Breaking the trade-off between fast control and long lifetime of a superconducting qubit
Shingo Kono, Kazuki Koshino, Dany Lachance-Quirion +4
The rapid development in designs and fabrication techniques of superconducting qubits has helped making coherence times of qubits longer. In the near future, however, the radiative…
On-demand generation and characterization of a microwave time-bin qubit
Jesper Ilves, Shingo Kono, Yoshiki Sunada +4
Superconducting circuits offer a scalable platform for the construction of large-scale quantum networks where information can be encoded in multiple temporal modes of propagating m…
