A superconducting qutrit link beyond the qubit limit
Xiang Li, Zheng-Yang Mei, Yang He +7
Superconducting microwave links have enabled deterministic state transfer and remote entanglement between qubits, but deterministic links have so far operated with an effectively t…
Fabrication and Characterization of Impedance-transformed Josephson Parametric Amplifier
Zhengyang Mei, Xiaohui Song, Xueyi Guo +10
In this paper, we introduce a method of using a double-layer resist lift-off process to prepare the capacitor dielectric layer for fabricating impedance-engineered Josephson parame…
On-demand shaped photon emission based on a parametrically modulated qubit
Xiang Li, Sheng-Yong Li, Si-Lu Zhao +13
In the circuit quantum electrodynamics architectures, to realize a long-range quantum network mediated by flying photon, it is necessary to shape the temporal profile of emitted ph…
Tunable coupling of a quantum phononic resonator to a transmon qubit with flip-chip architecture
Xinhui Ruan, Li Li, Guihan Liang +16
A hybrid system with tunable coupling between phonons and qubits shows great potential for advancing quantum information processing. In this work, we demonstrate strong and tunable…
