Vibration-Assisted Multi-Photon Resonance and Multi-Ion Excitation
Wenjun Shao, Xun-Li Feng, Jian Li +1
We investigate the multi-photon resonance and multi-ion excitation in a single-mode cavity with identical vibrating ion-qubits, which enables the tripartite interaction among the i…
High precision displacement sensing of monolithic piezoelectric disk resonators using a single-electron transistor
Jian Li, Jorge Santos, Mika Sillanpaa
A single-electron transistor (SET) can be used as an extremely sensitive charge detector. Mechanical displacements can be converted into charge, and hence, SETs can become sensitiv…
Hybrid circuit cavity quantum electrodynamics with a micromechanical resonator
J. M. Pirkkalainen, S. U. Cho, Jian Li +3
Hybrid quantum systems with inherently distinct degrees of freedom play a key role in many physical phenomena. Famous examples include cavity quantum electrodynamics, trapped ions,…
Dielectric losses in multi-layer Josephson junction qubits
David Gunnarsson, Juha-Matti Pirkkalainen, Jian Li +4
We have measured the excited state lifetimes in Josephson junction phase and transmon qubits, all of which were fabricated with the same scalable multi-layer process. We have compa…
Motional Averaging in a Superconducting Qubit
Jian Li, M. P. Silveri, K. S. Kumar +8
Superconducting circuits with Josephson junctions are promising candidates for developing future quantum technologies. Of particular interest is to use these circuits to study effe…
Dynamical decoupling of superconducting qubits
Jian Li, G. S. Paraoanu
We show that two superconducting qubits interacting via a fixed transversal coupling can be decoupled by appropriately-designed microwave feld excitations applied to each qubit. Th…
