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…

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…
