Manipulating complex hybrid entanglement and testing multipartite Bell inequalities in a superconducting circuit
Yuwei Ma, Xiaoxuan Pan, Weizhou Cai +9
Quantum correlations in observables of multiple systems not only are of fundamental interest, but also play a key role in quantum information processing. As a signature of these co…
Realization of two-dimensional crystal of ions in a monolithic Paul trap
Ye Wang, Mu Qiao, Zhengyang Cai +9
We present a simple Paul trap that stably accommodates up to a couple of dozens of \ensuremath{^{171}\mathrm{Yb}^+~} ions in a stationary two-dimensional lattice. The trap is const…
Experimental implementation of universal nonadiabatic geometric quantum gates in a superconducting circuit
