Implementation of a scalable universal two-qubit quantum processor with electron and nuclear spins in a trapped ion
Ji Bian, Teng Liu, Qifeng Lao +5
Increasing the quantum information processing power with limited number of hosts is vital for achieving quantum advantage. Here we propose a novel scheme that achieves a scalable n…

Dynamical topology of chiral and nonreciprocal state transfers in a non-Hermitian quantum system
Pengfei Lu, Yang Liu, Qifeng Lao +6
The fundamental concept underlying topological phenomena posits the geometric phase associated with eigenstates. In contrast to this prevailing notion, theoretical studies on time-…

Experimental demonstration of enhanced violations of Leggett-Garg inequalities in a -symmetric trapped-ion qubit
Pengfei Lu, Xinxin Rao, Teng Liu +4
The Leggett-Garg inequality (LGI) places a bound for the distinction between quantum systems and classical systems. Despite that the tests of temporal quantum correlations on LGIs…
