Phonon engineering of atomic-scale defects in superconducting quantum circuits
Mo Chen, John Clai Owens, Harald Putterman +2
Noise within solid-state systems at low temperatures, where many of the degrees of freedom of the host material are frozen out, can typically be traced back to material defects tha…
Characterizing temperature and strain variations with qubit ensembles for their robust coherence protection
Guoqing Wang, Ariel Rebekah Barr, Hao Tang +5
Solid-state spin defects, especially nuclear spins with potentially achievable long coherence times, are compelling candidates for quantum memories and sensors. However, their curr…
Vacuum-gap transmon qubits realized using flip-chip technology
Xuegang Li, Yingshan Zhang, Chuhong Yang +26
Significant progress has been made in building large-scale superconducting quantum processors based on flip-chip technology. In this work, we use the flip-chip technology to realiz…
Transmon qubit with relaxation time exceeding 0.5 milliseconds
Chenlu Wang, Xuegang Li, Huikai Xu +25
By using the dry etching process of tantalum (Ta) film, we had obtained transmon qubit with the best lifetime (T1) 503 us, suggesting that the dry etching process can be adopted in…
Realisation of adiabatic and diabatic CZ gates in superconducting qubits coupled with a tunable coupler
Huikai Xu, Weiyang Liu, Zhiyuan Li +11
High fidelity two-qubit gates are fundamental for scaling up the superconducting number. We use two qubits coupled via a frequency-tunable coupler which can adjust the coupling str…
Characterize noise correlation and enhance coherence via qubit motion
Jiaxiu Han, Zhiyuan Li, Jingning Zhang +11
The identification of spacial noise correlation is of critical importance in developing error-corrected quantum devices, but it has barely been studied so far. In this work, we uti…
A synthetic monopole source of Kalb-Ramond field in diamond

Magnetic monopoles play a central role in various areas of fundamental physics, ranging from electromagnetism to topological states of matter. While their observation is elusive in…
Probabilistic magnetometry with two-spin system in diamond
Raúl Coto, Hossein T. Dinani, Ariel Norambuena +2
Solid-state magnetometers like the Nitrogen-Vacancy center in diamond have been of paramount importance for the development of quantum sensing with nanoscale spatial resolution. Th…
All-optical quantum sensing of rotational Brownian motion of magnetic molecules
Changhao Li, Mo Chen, Dominika Lyzwa +1
Sensing local environment through the motional response of small molecules lays the foundation of many fundamental technologies. The information of local viscosity, for example, is…
Efficient quantum error correction of dephasing induced by a common fluctuator
David Layden, Mo Chen, Paola Cappellaro
Quantum error correction is expected to be essential in large-scale quantum technologies. However, the substantial overhead of qubits it requires is thought to greatly limit its ut…
