Verified Universal Breakdown of Kibble-Zurek Scaling in Fast Quenches
Xinxin Rao, Yang Liu, Mingshen Li +3
The Kibble-Zurek mechanism (KZM) predicts that when a system is driven through a continuous phase transition, the density of topological defects scales universally with the quench…
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…
Implementation of electromagnetic analogy to gravity mediated entanglement
Ji Bian, Teng Liu, Pengfei Lu +5
Recently, experiments aimed at measuring gravity mediated entanglement (GME) using quantum information techniques have been proposed, based on the assumption that if two systems ge…
Protection of quantum evolutions under parity-time symmetric non-Hermitian Hamiltonians by dynamical decoupling
Ji Bian, Kunxu Wang, Pengfei Lu +7
Parity-time (PT) symmetric non-Hermitian Hamiltonians bring about many novel features and interesting applications such as quantum gates faster than those in Hermitian systems, and…
Quantum simulation of a general anti-PT-symmetric Hamiltonian with a trapped ion qubit
Ji Bian, Pengfei Lu, Teng Liu +7
Non-Hermitian systems satisfying parity-time (PT) symmetry have aroused considerable interest owing to their exotic features. Anti-PT symmetry is an important counterpart of the PT…
Design of a novel monolithic parabolic-mirror ion-trap to precisely align the RF null point with the optical focus
Zhao Wang, Ben-Ran Wang, Qing-Lin Ma +6
We propose a novel ion trap design with the high collection efficiency parabolic-mirror integrated with the ion trap electrodes. This design has three radio frequency (RF) electrod…
