Strong coherent ion-electron coupling using a wire data bus
Baiyi Yu, Ralf Betzholz, Jianming Cai
Ion-ion coupling over long distances represents a highly useful resource for quantum technologies, for example, to sympathetically cool or interconnect qubits in ion-based quantum-…
Precise Spectroscopy of High-Frequency Oscillating Fields with a Single-Qubit Sensor
Yaoming Chu, Pengcheng Yang, Musang Gong +5
Precise spectroscopy of oscillating fields plays significant roles in many fields. Here, we propose an experimentally feasible scheme to measure the frequency of a fast-oscillating…
Transient dynamics of parametric driving for single-electron image current detection in a Paul trap
Baiyi Yu, Andris Huang, Isabel Sacksteder +1
Nondestructive detection of single-electron motion is crucial for quantum information processing with electrons trapped in Paul traps. The standard approach in Penning traps is to…
Engineered Randomness for Ubiquitous Quantum-Enhanced Metrology in Exponential-Dimensional Manifolds
Yaoming Chu, Baiyi Yu, Hartmut Häffner +3
The exponential growth of many-body Hilbert space presents a fundamental barrier to quantum technology, obscuring the search for physically significant states within an astronomica…
Engineering artificial atomic systems of giant electric dipole moment
Baiyi Yu, Yaoming Chu, Ralf Betzholz +2
The electric dipole moment (EDM) plays a crucial role in determining the interaction strength of an atom with electric fields, making it paramount to quantum technologies based on…
Dynamic framework for criticality-enhanced quantum sensing
Yaoming Chu, Shaoliang Zhang, Baiyi Yu +1
Quantum criticality, as a fascinating quantum phenomenon, may provide significant advantages for quantum sensing. Here we propose a dynamic framework for quantum sensing with a fam…
