Temporal Dynamical Quantum Phase Transition in Dicke Model with Trapped Ions
Ji Bian, Wei Wu, Zihan Xie +8
Temporal non-analyticities in the rate function of the Loschmidt echo manifests a class of dynamical quantum phase transitions (DQPTs) that has emerged as a powerful framework for…
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…
Discrimination of Chiral Molecules through Holonomic Quantum Coherent Control
Teng Liu, Fa Zhao, Pengfei Lu +5
A novel optical method for distinguishing chiral molecules is proposed and validated within a quantum simulator employing a trapped-ion qudit. This approach correlates the sign dis…
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…
Zero- to ultralow-field nuclear magnetic resonance and its applications
Min Jiang, Ji Bian, Qing Li +6
As a complementary analysis tool to conventional high-field NMR, zero- to ultralow-field (ZULF) NMR detects nuclear magnetization signals in the sub-microtesla regime. Spin-exchang…
Coherence induced work in quantum heat engines with Larmor precession
Shanhe Su, Wei Shen, Jincan Chen +4
The impacts of quantum coherence on nonequilibrium thermodynamics become observable by dividing the heat and work into the conventional diagonal part and the other part relaying on…

We derive the explicit solution of the problem of time-optimal control by a common magnetic fields for two independent spin- particles. Our approach is based on the Po…
Universal Quantum Control in Zero-field Nuclear Magnetic Resonance
Ji Bian, Min Jiang, Jiangyu Cui +7
This paper describes a general method for manipulation of nuclear spins in zero magnetic field. In the absence of magnetic fields, the spins lose the individual information on chem…
