A microfabricated surface ion trap on a high-finesse optical mirror
Peter F. Herskind, Shannon X. Wang, Molu Shi +3
A novel approach to optics integration in ion traps is demonstrated based on a surface electrode ion trap that is microfabricated on top of a dielectric mirror. Additional optical…
Superconducting microfabricated ion traps
Shannon X. Wang, Yufei Ge, Jaroslaw Labaziewicz +3
We fabricate superconducting ion traps with niobium and niobium nitride and trap single 88Sr ions at cryogenic temperatures. The superconducting transition is verified and characte…
Quantum codes give counterexamples to the unique pre-image conjecture of the N-representability problem
Samuel A. Ocko, Xie Chen, Bei Zeng +4
It is well known that the ground state energy of many-particle Hamiltonians involving only 2-body interactions can be obtained using constrained optimizations over density matrices…
A cryogenic surface-electrode elliptical ion trap for quantum simulation
Robert J. Clark, Ziliang Lin, Kenan S. Diab +1
Two-dimensional crystals of trapped ions are a promising system with which to implement quantum simulations of challenging problems such as spin frustration. Here, we present a des…
A surface electrode point Paul trap
Tony Hyun Kim, Peter F. Herskind, Taehyun Kim +2
We present a model as well as experimental results for a surface electrode radio-frequency Paul trap that has a circular electrode geometry well-suited for trapping of single ions…
Tensor product representation of topological ordered phase: necessary symmetry conditions
Xie Chen, Bei Zeng, Zheng-Cheng Gu +2
The tensor product representation of quantum states leads to a promising variational approach to study quantum phase and quantum phase transitions, especially topological ordered p…
